Post migration you might start having issues with mobile devices using ActiveSync not synchronising correctly with Exchange Server 2010. It might work for a couple of days and then stop working. During this time users don’t receive any email to their mobile devices, but they can send email.
You might also get an error on the iPhone Cannot Get Mail, The connection to the server failed.
You might be using Quest Migration Manager for Exchange v8.7, and in the mail source and target agent logs you might see entries similar to this.

What is happening here is Quest Migration Manager for Exchange is synchronising the ExchangeSyncData folder from the source mailbox to the target mailbox. The entries are not needed on the target as fresh new sync partnerships will be be created by the mobile device.
Download an application called MFCMAPI from http://mfcmapi.codeplex.com/ and use this to connect to the user’s mailbox having the problem.
- Get the user to delete the mail account from their mobile device
- Open MFCMAPI > click Session > Logon and display store table
- Create a new profile and add the user’s mailbox
- Expand ExchangeSyncData and delete all the folders that exist under here.
- Get the user to re-create their mail account on their mobile device.
