Why Does Google Data Migration Stuck at 99?

Sometimes, you will see that the status bar is not progressing. It mostly happens at 0% or 99%. Whenever you encounter the Google mailbox data migration stuck at 99% issue, it is because of either of the reasons:

• Migration of Gmail email that already existed in the destination mailbox. It happens when you have the same email in more than one folder of the source email account and one of these emails is already migrated. The Google Data Migration service is trying to label the emails and hence is stuck at 99%.
• When the number of migrated emails is greater than the number of emails discovered for migration. You will see that the progress bar is not moving.
• It also happens that the migration process has already failed or stopped but the status bar is not updating. When you hover the cursor over the status bar, you will see “Mailbox estimation failed”.
