Hi @Amit Badgujar

According to the error information you provided above, the issue is caused by source Google Apps account is disabled or the account has a problem with Google authentication.

You may try the solution below to resolve this issue:

Please check following issues:

1. User doesn’t exist
2. User is suspended
3. Password has expired

Enable the source Google Apps account

Then restart the migration.

Hi @Amit Badgujar ,

I'm running into the same problem (see https://learn.microsoft.com/en-us/answers/questions/1025313/34fatal-error-googlepermanentwebexception-has-occu.html)
However, I can't find any error details on the GooglePermanentWebException error. How did you find the details (the full message) of this error?

Thanks for your help!
Robert

Hello

We have same problem, solved with 2 steps in this link:

OAuth Scopes

At the wizard on O365 TENAT i have choose Automated - through the New Exchange admin center, but like we now, that don't do it everything.

Also i have do 2 steps manual on the GSuite or Google Workspace Admin page site:

• Enable API usage in your project
• Grant access to the service account for your Google tenant

Hope it will helps to someone else.

Answer 4

I encountered the same issue during the migration of Google to M365. Even all the prerequisites appear met, but when I looked at the parameters found two problems.

1. Under Domain wide delegation section there were only four URLs authorized.
2. Only Gmail API was enabled while we need Calander and Contacts enabled as well.

Here's the steps to fix that problem:

• Open the Domain Wide Delegation page and add the below URLs

https://www.googleapis.com/auth/gmail.settings.sharing https://www.google.com/m8/feeds https://www.googleapis.com/auth/contacts.readonly https://www.googleapis.com/auth/calendar.readonly https://www.googleapis.com/auth/admin.directory.group.readonly https://www.googleapis.com/auth/admin.directory.user.readonly https://sites.google.com/feeds/ https://www.googleapis.com/auth/gmail.settings.basic

• Use the below URL to enable the missing APIs https://console.developers.google.com/apis/library

Answer 5

You need to ensure the calendar API is enabled.
