Thankyou!

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!’
