Question

Failed to parse element: VersionOverrides error logged after 365 update

Jak22 45

Starting after updating to version 19628.20106 or newer, several times a day there is Error Event 300 logged

Failed to parse element: VersionOverrides

DisplayName=Microsoft Forms

It might start after using desktop Outlook Classic

In this past fixes involved apps/add-ins that could be deselected but DisplayName=Microsoft Forms seems to be something new

I checked into this. The reason for getting Event ID 300 is because the teams that develop the Microsoft add-ins do not include versionOverrides element in the manifest of the add-ins. This element is optional, and the teams do not us use it, so they omit it. This event does not indicate an issue with the add-in, and you will not encounter any errors when using it.

The error message Failed to parse element: VersionOverrides typically indicates an issue with the manifest of an add-in, particularly after updates to Microsoft 365 applications. This error can occur if there are changes in the structure or required elements of the manifest that are not being met by the current version of the add-in.

In your case, since the error started appearing after updating to version 19628.20106 or newer, it may be related to how the Microsoft Forms add-in is handling the new version requirements. Here are a few steps you can take to troubleshoot this issue:

Check for Add-in Updates: Ensure that the Microsoft Forms add-in is up to date. Sometimes, add-ins need to be updated to be compatible with new versions of Outlook.
Review the Manifest: If you have access to the add-in's manifest file, review it for any discrepancies or missing elements, especially the VersionOverrides section.
Disable Conflicting Add-ins: If you have other add-ins installed, try disabling them to see if there is a conflict causing this error.
Repair Office: Running a repair on your Office installation can sometimes resolve issues related to add-ins.
Contact Support: If the issue persists, consider reaching out to Microsoft support for further assistance, as they may have insights specific to the recent updates.

This error is not uncommon after updates, and it often requires adjustments either to the add-in or the environment it operates in.
