Exchange Mailbox Migration not Working
At one of my sites, we have recently installed a new 2013 exchange server to replace the existing 2010 box. We have successfully setup the mailboxes and new mail is arriving as we would like. Now for the old mail, we are trying to run Microsofts recommended new-mailboxexportrequest. This has given us the PSTs but we are struggling to import them. They sit queued with no errors for hours and never complete.
We have tested the PST and all look OK, Outlook can open them fine. The files are unicode . We have also tried PST Capture which completes but only seems to import the deleted mail for some reason.
Does anybody have any ideas? We have DPM for backup and thought we could restore the database from old server to new one and migrate, or we could export new mailbox, restore old mailbox database and replace it?
