I am trying really hard to wrap my head around why people insist on using this program...
Where I have outlook 2013 users, I have had nothing but problems getting their mail to work with imap. my solution has been to set them up with pop, which works just like it always has. Or move them to a different program.
recently, I have a customer who requires multiple machines, all using outlook 2013, to access the same email address, so pretty much have to use imap. if I set up just one of the machines with imap, it works more less as expected, with hiccups such as mail taking an hour or two or more to show up. But shortly after I connect a 2nd machine to the same account, one or both machines start to go wonky. Symptoms include deleted items returning, read messages becoming unread again, and duplicates being constantly created and deleted. The last I can confirm by watching in webmail and refreshing the inbox every few seconds; as mail shows up and deletes in outlook, so it does in webmail too.
On my test machine connected to the same server, I have evolution, outlook and thunderbird all connecting to one account with no problems. Well, outlook hiccups, but it's not unusable. And I have other users on the system that share email accounts across a variety of other clients and platforms, including older versions of outlook.
I have tried checking message rules, there are none; removing all folder subscriptions; running scanpst, which finds errors even before the account finishes syncing and ever time I run it after that; I have looked for viruses/malware; I have confirmed there is no forwarding or some trickery happening on the server; chkdsk and similar hardware checks all come up clean, the computers are only a couple of months old; I have got certs set up with SANs and the CA installed such that outlook does not error on the certificate; and I have tried just about every combination of settings that seem relevant.
The one thing that does seem to work, at least for a few minutes or an hour or two, is deleting and recreating the accounts on one of the computers. But the problem inevitably returns in short order.
Surely people have outlook 2013 connecting via imap to dovecot without problems; is there some special trick that google is hiding from me?
