Hi Team,
I am in process of migrating 200+ user mailbox to Office 365. Where most of all user mailbox got migrated except 2. One is in synced state and another one is still in migration (due to huge size). For these 2 mailbox all of the sudden i noticed that the EAC gives the error message as "
The subscription for the migration user ****@keyman .com couldn't be loaded. The following error was encountered: A subscription wasn't found for this user.." For the synced mailbox the license was unassigned (not sure how) and so I have assigned it and resumed the migration but still the same.
Please help

@Eric Yin-MSFT Issue is still there. I have 2 mailboxes which are still not completed.
For Mailbox 1, the completion is given last week but still not completed and the user is using G-Suite.
For Mailbox 2, the status in the migration batch is synced whereas the user started receiving the emails in Office 365 and all emails are also available. But still the migration status isn't getting updated as completed.
I have contacted the migration support but no proper response for almost 7+days.
Still same error inforamtion this time?
Is mail flow working for mailbox1 ?
Looks like there was some issue at Microsoft backend. The Gsuite term was changed to Google Workspace. I have created a new migration end point with new JSON file and that have fixed the issue.

Hi @Sabarish Natarajan ,
Based on the Troubleshooting guide it looks like you may need to stop and restart the migration batch again to get this resolved.
Resolution
Another solution you can try if that does not work is this suggestion in this blog post by Tech Trainer.
If the GUIDS are not matching, that would be the problem.
The resolution is to run the command below and rerun “Complete-Migrationbatch” cmdlet:
Set-RemoteMailbox UserB -ExchangeGUID 4a502e5e-5064-4f60-b691-845bdaf94113 #Online MailboxGUID
If the “Get-RemoteMailbox” does not return anything for the user it means that it wasn’t migrated successfully.
In that case, you have to remove the online mailbox for the user as described in the post.
I would recommend checking this post as well.
@MarileeTurscak : I have tried that multiple times also the remote mailbox command works only for Exchange On-premises to Online migration. Currently I am performing Gsuite to Office 365 migration.
