Hi,
I'm doing a migration from Gmail to O365. Created IMAP migration points, but for some users and after a few days the sync fails with the following error: "Transient error RemoteNetworkErrorTransientException has occurred. The system will retry". It will retry for 60 times and then it stops the sync and no resume on the next day. This error happen often on the users with biggest mailboxes, but mailbox size does not reach 50GB, the biggest one in O365 is 33GB. For me this error network error is a bit strange, because the migration point is a connection between cloud services.
Also, I do not understand why, but mailbox size in O365 is doubled when compared with Gmail, I've noticed there is mail duplication on O365 archive folder, and this could explian the double size. How to avoid the fill of archive on the migration?
