As typical this was a thoughtful post today. You make me want to preserve coming back again and forwarding it my followers…….

I’ve actually had to embark on a Zarafa -> Exchange migration (personal project gone arwy :-/) and thus far (with your original pointers) this seems to be working and has the plus of not duplicating messages for every run (useful for large mailboxes with 200K+ messages specially when you’re sharing Virtualbox hosts ):

imapsync –fast –subscribe –noauthmd5 –skipsize –syncinternaldates –host1 [sourcehost] –host2 [desthost] –password1 [sourcepassword] –password2 [destpassword] –skipheader ‘^Content-Type’ –user1 [sourceuser] –user2 [destuser] –regexflag ‘s/receipt-handled//’ –regexflag ‘s/$Forwarded Forwarded//’ –regexflag ‘s/\Answered//’ –sep1 “/” –prefix1 “” –useheader ‘Message-ID’

Hopefully we’ll all be good now as I cowtow to the missus saying ‘to just give me my mail/calendars/contacts!’

About the migration – I’m not happy with it but there was so much resistance to a non-MS solution even after the Zimbra trial, that it was impossible to keep the Zimbra server. Most likely it had something to do with our first few attempts at email server which were all F/LOSS based and were all flops to some degree or another, so much that even though Zimbra had delivered, people still wanted their MS fix.

And sorry for the forced migration to Exchange. We’ll be here for you if and when your workplace reconsiders their choice of mail server…
