MAUTHACCESSTOKENINVALID

Migration Manager could not call the Google Drive API because the access token is invalid or expired.

Why it happens

Connector authorisation failed. The API request was rejected because the access token (the credential Migration Manager uses to call Google) is invalid or expired. Microsoft links the fix to the Drive and Docs service status in Google Workspace.

How to fix it

1. 1

   Step 1

   Sign in to the Google Admin console with an admin account.

2. 2

   Step 2

   Go to Apps > Google Workspace > Service Status.

3. 3

   Step 3

   Set the service status of Drive and Docs to ON for everyone.

4. 4

   Step 4

   Return to Migration Manager and rerun the scan or migration task.
