What does Microsoft Forms Error 800a01a8 mean? - excel

Picture of Office Applications Sync Turned Off Picture of Error Received at Workbook Close and Save I have a workbook that is an "Import Sheet" for our users to enter information either via manual entry, data validation drop downs, or userform. Everything works great until I close the workbook and tell it to save. I receive this error:
"Microsoft Forms (<- Title) Could not complete the operation due to error 800a01a8."
I thought originally it might have something to do with interrupting the OneDrive/Sharepoint sync but based on my internet sleuthing I've discovered that you can prevent the sync from happening by going into the OneDrive settings and unchecking the "Use Office applications to sync Office files" option and it doesn't seem to be syncing upon close anymore, however my problem persists. I am unable to find much on this specific error, if anyone has any ideas please let me know. I would be willing to provide code if someone could point me in the right direction of which code could be the problem (i.e. - BeforeClose sub, BeforeSave sub, etc.) If someone is so inclined to dig deep enough I'd provide the whole workbook purely in the interest of resolving this issue.

User unable to open or save workbook with VBA code

This has me stumped. The user is able to work with workbooks containing the same code that were produced previously. Just recently new workbooks with the same code in them cannot be opened or saved. There are a range of error messages depending on where the workbook is opened from - we have tried safe locations, local folders and Dropbox folders. We have also tried with code signed and unsigned workbooks.
Error messages include:
'Excel cannot open the file Test.xslm because the file format or extension is not valid...' (not true, as I can open the same workbook and run the code without problem).
'Your changes to Text.xlsm could not be saved due to a sharing violation...' (followed by more errors to do with not finding a temporary document).
I have also tried removing ActiveX references which might flag as a security issue, (e.g. VBIDE) and commenting out blocks of code. No joy. Microsoft Defender reports no issues. There are no other antivirus programs running. There are no problems with the same workbooks with the VBA modules removed completely - so it definitely looks code related.
Anyone have any ideas?
This might be because of ASR.
If you check your "Windows Security" --> Virus & threat protection --> Protection history, you should find an event of "Risky action blocked" that shows your file has been "Blocked by: Attack surface reduction" Rule: Block Win32 API calls from Office macro".
I'm currently facing a very similar issue but I'm on the other side (I am the one that enabled ASR rules).
If that is the case for you as well, I wonder whether the problem depends on the identity that you use to save the file through your macro. Are you using the same security context of the user executing Excel?

Macro Enable Workbook is creating new file with SaveAsUI instead of saving itselft

I have to call the below line to save my workbook from another file:
Application.ActiveWorkbook.Save
For the needs of my project, this code needs to be and run in a different file than the one I have open and active.
When this code runs from another workbook, the file that I have it open and actived calls the SaveAsUI to save the file again, even if he was already saved.
Afther run of the code above, the original workbook is losted. I cannot save anymor the active workbook, manually or by macros, and I don't want to save as my original file. Several errors occur, such as:
random filename in the SaveAsUI
Unespected Error, AutoRecover Disabled
Share Rule Violation (PT/BR)
Sorry, I cannot catch this erro in english. Here its translation:
"Your changes could not be saved in 'File' due to a sharing violation. Try saving to another file."
I noticed that this error started after I enabled auto-save for the first time*. I don't know if it is something related to the cloud and Excel gets lost when saving. Also, testing saving the original file outside the network the problem did not appear
I haven't found anything like it on the internet and it has never happened before either.
PS: The workbook with I have enabled AutoSave has nothing to do with those that are giving error. That was a workbook without macros for a much simpler project.
I was able to find what was causing the problem. I initially thought it was the VBA macro part and the "ActiveWorkbook.save" command, but in the end the problem was much deeper.
It turns out that in the same macro that contained the save command there was a call to another function that updated the queries.
the error would stop when going into PowerQuery Editor, going into the spreadsheet query that would later give the share violation error, and in the steps remove the action of promoting the headers.
I have no idea why this is the error. But I tried several other ways in several other places (like every tip in this link1, or this link2, or this link3), the only way that resulted in the solution was this above (that I don't find in any place).
But the promotion of the headers is necessary, so to continue without giving problems I needed to go into the advanced editor and change the second parameter of the line below from "null" to "true" (which is basically to promote headers at the query stage).
let
Source = Excel.Workbook(File.Contents(FilePath), true, true),
With this, everthing now is working fine.

Add ActiveX component to Excel Spreadsheet [duplicate]

I have some Excel worksheets that use ActiveX checkboxes to control certain activity. They worked recently but today started to give errors. I was alerted to this by a colleague, but it was still working on my computer. I checked his version of Excel against mine and his was newer. I noticed there were new Windows updates, so I did the update. After I applied pending updates, it now no longer works on my computer. I cannot check the ActiveX checkboxes any longer, and, as a part of trying to debug, it appears I cannot even add an ActiveX control to any worksheet, even a new worksheet, any more. I get an error dialog that says, "Cannot insert object." (I can still add form controls, just not ActiveX.) Anyone else experiencing this after a recent update? Any suggestions?
Thanks,
Mike
From other forums, I have learned that it is due to the MS Update and that a good fix is to simply delete the file MSForms.exd from any Temp subfolder in the user's profile. For instance:
C:\Users\[user.name]\AppData\Local\Temp\Excel8.0\MSForms.exd
C:\Users\[user.name]\AppData\Local\Temp\VBE\MSForms.exd
C:\Users\[user.name]\AppData\Local\Temp\Word8.0\MSForms.exd
Of course the application (Excel, Word...) must be closed in order to delete this file.
Here is the best answer that I have found on the Microsoft Excel Support Team Blog
For some users, Forms Controls (FM20.dll) are no longer working as
expected after installing December 2014 updates. Issues are
experienced at times such as when they open files with existing VBA
projects using forms controls, try to insert a forms control in to a
new worksheet or run third party software that may use these
components.
You may received errors such as:
"Cannot insert object" "Object library invalid or contains references
to object definitions that could not be found"
Additionally, you may be unable to use or change properties of an
ActiveX control on a worksheet or receive an error when trying to
refer to an ActiveX control as a member of a worksheet via code.
Steps to follow after the update:
To resolve this issue, you must delete the cached versions of the
control type libraries (extender files) on the client computer. To do
this, you must search your hard disk for files that have the ".exd"
file name extension and delete all the .exd files that you find. These
.exd files will be re-created automatically when you use the new
controls the next time that you use VBA. These extender files will be
under the user's profile and may also be in other locations, such as
the following:
%appdata%\Microsoft\forms
%temp%\Excel8.0
%temp%\VBE
Scripting solution:
Because this problem may affect more than one machine, it is also
possible to create a scripting solution to delete the EXD files and
run the script as part of the logon process using a policy. The script
you would need should contain the following lines and would need to be
run for each USER as the .exd files are USER specific.
del %temp%\vbe\*.exd
del %temp%\excel8.0\*.exd
del %appdata%\microsoft\forms\*.exd
del %appdata%\microsoft\local\*.exd
del %appdata%\Roaming\microsoft\forms\*.exd
del %temp%\word8.0\*.exd
del %temp%\PPT11.0\*.exd
Additional step:
If the steps above do not resolve your issue, another step that can be
tested (see warning below):
On a fully updated machine and after removing the .exd files, open the file in Excel with edit permissions.
Open Visual Basic for Applications > modify the project by adding a comment or edit of some kind to any code module > Debug > Compile
VBAProject.
Save and reopen the file. Test for resolution. If resolved, provide this updated project to additional users.
Warning: If this step resolves your issue, be aware that after deploying this updated project to the other users, these users will
also need to have the updates applied on their systems and .exd files
removed as well.
If this does not resolve your issue, it may be a different issue and
further troubleshooting may be necessary.
Microsoft is currently working on this issue. Watch the blog for
updates.

It was KB2553154. Microsoft needs to release a fix. As a developer of Excel applications we can't go to all our clients computers and delete files off them. We are getting blamed for something Microsoft caused.
I'm an Excel developer, and I definitely felt the pain when this happened. Fortunately, I was able to find a workaround by renaming the MSForms.exd files in VBA even when Excel is running, which also can fix the issue. Excel developers who need to distribute their spreadsheets can add the following VBA code to their spreadsheets to make them immune to the MS update.
Place this code in any module.
Public Sub RenameMSFormsFiles()
Const tempFileName As String = "MSForms - Copy.exd"
Const msFormsFileName As String = "MSForms.exd"
On Error Resume Next
'Try to rename the C:\Users\[user.name]\AppData\Local\Temp\Excel8.0\MSForms.exd file
RenameFile Environ("TEMP") & "\Excel8.0\" & msFormsFileName, Environ("TEMP") & "\Excel8.0\" & tempFileName
'Try to rename the C:\Users\[user.name]\AppData\Local\Temp\VBE\MSForms.exd file
RenameFile Environ("TEMP") & "\VBE\" & msFormsFileName, Environ("TEMP") & "\VBE\" & tempFileName
End Sub
Private Sub RenameFile(fromFilePath As String, toFilePath As String)
If CheckFileExist(fromFilePath) Then
DeleteFile toFilePath
Name fromFilePath As toFilePath
End If
End Sub
Private Function CheckFileExist(path As String) As Boolean
CheckFileExist = (Dir(path) <> "")
End Function
Private Sub DeleteFile(path As String)
If CheckFileExist(path) Then
SetAttr path, vbNormal
Kill path
End If
End Sub
The RenameMSFormsFiles subroutine tries to rename the MSForms.exd files in the C:\Users\[user.name]\AppData\Local\Temp\Excel8.0\ and C:\Users\[user.name]\AppData\Local\Temp\VBE\ folders to MSForms - Copy.exd.
Then call the RenameMSFormsFiles subroutine at the very beginning of the Workbook_Open event.
Private Sub Workbook_Open()
RenameMSFormsFiles
End Sub
The spreadsheet will try to rename the MSForms.exd files when it opens. Obviously, this is not a perfect fix:
The affected user will still experience the ActiveX control errors when running the VBA code the very first time opening the spreadsheet. Only after executing the VBA code once and restarting Excel, the issue is fixed. Normally when a user encounters a broken spreadsheet, the knee-jerk reaction is to close Excel and try to open the spreadsheet again. :)
The MSForms.exd files are renamed every time the spreadsheet opens, even when there's no issue with the MSForms.exd files. But the spreadsheet will work just fine.
At least for now, Excel developers can continue to distribute their work with this workaround until Microsoft releases a fix.
I've posted this solution here.
With Windows 8.1 I couldn't find any .exd files using windows search. On the other hand, a cmd command dir *.exd /S found the one file on my system.
Advice in KB and above didn't work for me. I discovered that if one Excel 2007 user (with or without the security update; not sure of exact circumstances that cause this) saves the file, the original error returns.
I discovered that the fastest way to repair the file again is to delete all the VBA code. Save. Then replace the VBA code (copy/paste). Save. Before attempting this, I delete the .EXD files first, because otherwise I get an error on open.
In my case, I cannot upgrade/update all users of my Excel file in various locations. Since the problem comes back after some users save the Excel file, I am going to have to replace the ActiveX control with something else.
The best source of information and updates on this issue I could find is in the TechNet Blogs » The Microsoft Excel Support Team Blog (as mentioned):

Simplified instructions for end-users. Feel free to copy/paste the following.
Here’s how to fix the problem when it comes up:
Close all your Office programs and files.
Open Windows Explorer and type %TEMP% into the address bar, then press Enter. This will take you into the system temporary folder.
Locate and delete the following folders: Excel8.0, VBE, Word8.0
Now try to use your file again, it shouldn't have any problems.
You might need to wait until the problem occurs in order for this fix to work. Applying it prematurely (before the Windows Update gets installed on your system) won't help.
I did finally find this answer on the official Microsoft KB:
http://support.microsoft.com/kb/3025036/EN-US
No new information here than what we have in previous answers, but at least it acknowledges that Microsoft is aware of the issue.
I know many answers have already been posted for this, but neither one answer independently worked for my site. So here is what worked for me:
Step 1: Uninstall the following updates - KB2920789, KB2920790, KB2920792, KB2920793, KB2984942, KB2596927
Step 2: Hide these updates so they do not get installed on subsequent reboots
Step 3: Delete folder Excel8.0 from C:\Users\<>\AppData\Local\Temp
Step 4: Restart workstatiion (I would also make sure the above mentioned KBs did not inadvertently get applied)
I want to provide an answer that worked as the only thing for me (I realize that I might be the only one ever). I had in one macro that I was calling using the ribbon. It had the following code:
colStore = new Collection
I wasn't aware that it throws an error so I was baffled and tried everything in here. The button just stopped working and I couldn't get it to work. When I noticed the error and corrected it to:
Set colStore = new Collection
It started working again. Absolutely strange if you ask me but maybe it helps someone out there who was as desperate as me.

Expanding Custom Class node in Locals window silent crashes excel

The issue:
Similar to this issue but unable to find a solution I am trying to figure out how to fix this bug:
Viewing an object in Locals or Watch window causes excel to crash
The custom class is as wrapper for ADO execution allowing us to use a separate class to maintain our SQL code and execute it within the wrapper to keep error handling for MS Access ADO execution in one neat place.
This has been great for logging and debugging purposes until a few days ago I noticed trying to expand the node for the custom class in the Locals or Watch windows in the VBA editor cause Excel to silent crash after a 5 second hang and restart with the file recovery window.
Unfortunately the code is company sensitive so I may not be able to paste any in but if there are any ideas as to what might cause it I may be able to find the source and report back.
Has anyone else experienced this issue?
Update: New symptom - During debugging and comparing the text between an older build and the new one I found that the Locals window goes empty (clears of all objects) just after the hang stops and before the crash occurs.
Fixes I have tried:
Rebuilding VBA project and fixing all known compile errors (to eliminate simple vba errors)
Exporting all classes and modules - reimporting into new workbook (to eliminate the workbook file being corrupt)
Copying class and module text into notepad and clearing all formatting - pasting into new workbook (in an attempt to remove corrupt class data)
Disabling any reference to other custom classes to narrow down to a single class.
I appreciate your help and hope my issue can shed some light on it for others.
You can try below things. I hope any one of them work for you. If it still it does not works i request you to
simulate the similar issue for demo and share the code.
Possible issues with add-ins. Try to remove your addins (uninstall
the com addins) and run the code and check if you are still having
the issue.Disabling add-ins is a good test because it let you narrow
the choice of which add-in is causing the crash.
Check whether your antivirus software is up to date or is conflicting
with Excel. If your antivirus software is not up to date, Excel may
not function correctly.
Kindly run the macro on single instance of excel and check if you are
still having the issue. By single instance i mean when you go to task
manager processes tab where only one image name with excel.exe should
appear.
Verify/install the latest window updates
Try to run the same macro on other pc or other version of excel
Use mztools andin and review your code
