Quoting Bob Miller <bob@computerisms.ca>:
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.
I have no idea what your doing to cause this issue :(
I have a normal install of dovecot running, and I have 3 webmail pages
open, 2 phones using imap, and a thunderbird connected to it. I
started with outlook 2007, then 2010, and now 2013 for the last 2
years or 3years (I upgraded to it in beta at first). I haven't had any
issues at all, I can delete emails, move emails, ..., and they
instantly change in the other programs.
I just use the normal outlook2013 config options for the account,
besides making sure the ssl settings are right.
I think I have only used it on the 2.2 branch though, what dovecot
version are you using?
