When do you know when a mailbox has finished migrating all mail?
The Quest Migration Manager does not display a real-time progress indicator.
There are different ways to determine mail migration progress depending on your configuration.
1. If you have configured your collection to "auto switch" mailboxes, then once fully synchronized the mailbox will switch and you will see a "check" icon next to the mailbox in Migration Manager for the target mailbox.
2. Secondly, you can use your Exchange System Manager (Exchange Management Console for Exchange 2007) to compare email counts between your source and target mailboxes for particular users. If you are not using "auto switching" then this method will be a more practical method.
3. Statistics Agents can also be used to show progress in this regard. Please see the Migration Manager User Guide for further Information.
4. Viewing agent log files at any time will provide much information (hints) around collections experiencing trouble, progressing normally, or have completed successfully.
