Email migration may experience some exceptions due to the original email service settings.
Learn how to avoid issues from such settings and how to troubleshoot some common problems.

Example, ad emails of a special format
Cautions for email migration
- 1.During email migration, your original mailbox will receive a notification of login from a different location. This is caused by the email migration. You can just ignore it.
- 2.Don't change your email account password. Otherwise, the email migration will fail.
- 3.During the email migration, don't move emails to other folders. Otherwise, some emails may be omitted for migration.
