ODBC Connection To MS Access Failing After Upgrading to (Build 19426.20186)

[sjm334]

After updating PCs to the 9 Dec 2025 released build Version 2511 (Build 19426.20186), we began having trouble refreshing our data from an ODBC connection to Microsoft Access.  We receive the following error:

We had a few machines that had not yet taken the upgrade and we continue to be able to refresh data through the same connenction on those machines.  I believe it has to do with the version of the Access driver, which after taking this update is Build 19426.20186.

Has anyone else experienced similar problems?  Is there a fix in place that I may have missed?

The issue remains in Build 19530.20138 installed 1/12/2026.

Have Microsoft resolved the issue with the patch yet? Whenever my computer is restarted I am having to downgrade the update each time, so could do with this being fixed to resolve the issue.

Microsoft released an update to 19426.20186. However, we were still having problems with the update 19426.20218.  We rolled back on our gateway server and our ODBC connections began to refresh again. 

I have not tried these steps from another post, but it seems like Microsoft released a post with another possible solution.

@sjm334 This is an known issue reported by other users as well for this Dec version. But It didn’t happen on older builds.  Suggesting to re-install older version and try.

As @Praful_Potphode mentioned, you can roll back to previous version till the time the issue is fixed. This is the command which you can run in your command prompt to roll back to the old version.

Please note you might need system admin permissions in order to run this command 

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.19426.20170

@tharunkumarRTK While I do not have admin priviledges on my machine, I was able to have our end user device team apply this and it was successful.

Hi @sjm334 ,

this is a known issue introduced by the December 9, 2025 Office/Access update (Build 19426.20186, KB5072033). After this patch, ODBC connections to Access databases began failing with the error HY000 [Microsoft][ODBC Microsoft Access Driver] Operation is not supported for this type of object. Microsoft has acknowledged the regression, and the current guidance is to either roll back/uninstall the December update or wait for the fix in a subsequent Office patch
