Title
ODM: Public Folder migration error: "Error occurred while executing the request. InternalServerError (Internal Server Error)" -
Description
I have tried every troubleshooting steps but I just can't seem to get public folders to migrate this is the error we receive:
Reason: 'Error occurred while executing the request. InternalServerError (Internal Server Error) '
-
Cause
This behavior may occur if a "new" the first PF mailbox is created on the target and not enough time is given for propagation, then the Public Folder migration is kicked off instantly via ODM. -
Resolution
Steps to resolve this issue:
- Regrant consent to both source/target tenant.
- Confirm your migration account has global admin access on both source and target tenants.
- Confirm you have proper root-level permission set in the Exchange admin panel for Public folders.
- Confirm these permissions are set at the Public folder and sub folder levels
If the above steps still do not fix the issue the please proceed to do the following:
- Delete the "QuestTempFolder" which ODM creates during provisioning and to make sure it was propagated correctly within outlook.
- To confirm please execute PowerShell cmdlet like Get-Publicfolder -Recurse if you still see the folder then remove this folder.
- Run migration, the QuestTemFolder should be created again during provisioning and this time the Public Folder should migrate successfully.
