Hi,
Hoping that someone can get me out of this never ending problem, that no matter what I try and do doesn't resolve it.
We have a Exchange 2010 Environment, with Outlook 2013 clients connecting to it inside our internal network. Everything seems to be running smoothly, auto mail setup for new starters, address books, OWA, Outlook anywhere for outside the office except for Out of Office.
Some of my clients can connect to exchange and setup their out of office fine using their outlook client, others can't as they get an error that the server is unavailable.
I have tried absolutely everything to try and fix this, DNS changes, permission changes, recreated my virtual directories and now at a loose end.
The only thing I can put it down to is that we have 2 exchange servers running as cas servers and maybe some are connecting to one that works and others are connecting to the other that isnt working, but im not sure how to tell which is and isnt working as they seem to connect to our exchange all using the same name.
Any help or advisse would be greatly appreciated.
Thanks in advance.
