Server: Exchange 2007,
Clients: 2007, 2010, 2013, some older computers – 2003, all using cashed mode.
Everything was working fine up to this Monday (at least we have noticed this problem at this Monday).
Last Monday user with Outlook 2013 on Windows 7 64 bit was able to use “Out of office assistance”.
Yesterday, he has got the message: “Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later”.
This is only happening on 2013 Outlook clients. 2007 and 2010 Outlook clients are fine.
Outside and inside OWA is fine. Nothing has changed, only some MS updates were installed since last week.
More info: What is strange; if I will delete the Outlook 2013 profile for the user and create the new one, it sets up using autodiscover just fine, more, when Outlook starts updating the new *.ost file the “Out of office assistance” is working for about a minute or so, and then stops again.
I’ve ran the “Test e-mail AutoConfiguration…” test locally and its passing.
I’ve checked the local DNS and we have Exchange server, OWA and Autodiscover entry there.
Like I’ve said before, nothing, but updates, has changed. And 2007, 2010 clients are fine, that is only affecting 2013 clients, which use to work just fine until this week.
I’m lost. Please help.
