Hi,
I have a handful of Mac Mail users connecting to our Exchange 2013 server using the client (lion and mountain lion). It seems that across the board the syncing of the accounts with IMAP is HORRENDOUSLY slow (10kb/s at times). One user who has a 4gb mailbox has had apple mail syncing IMAP for days and still is not finished, same witht he other user...after a full day it had downloaded a mere 600mb.
If these users use the 'exchange' acount option in apple mail it syncs relatively quickly (couple hours) but they have other connection issues (separate item for another day/thread).
So it seems pretty consistent that mail application users on lion and mountain lion experience dialup speed syncing over IMAP and I would like to find out why, or if there is anything that can be done about it.
Thanks!
