Hi we're trying to run a test migration from Exchange 2007/SBS 2008 to Zentyal 3.5.. so far we've managed to get across our AD users/groups without too much hassle.
Where we're falling down is getting mailboxes over for our users -- this is an absolute requirement for us due to regulatory constraints.
There is a built-in tool (a technology preview feature), that you can access via a "/Migration/" URL on the server. Whilst this does claim it has connected, it then reports no mailboxes were found.
I've seen other possibilities for extracting the emails alone via imapsync but this would leave out Calendar entries.
We've also (successfully) extracted someones mail into .PST and then imported it back into Outlook on the new server. This, is fairly impractical given the ~70 users we have though.
Is anyone aware of another approach to this we could take to get our old mail/calenders out of Exchange?
