We have an on premise Exchange 2013 system and use Outlook 2013.
We are having an issue where folks that are connected to a VPN and using Outlook on their desktop cannot set an Out of Office message, MailTips also fails, but I suspect they are tied together.
The failure states: Your automatic reply settings cannot be displayed because the server is currently unavailble. Try again later.
In the network everything works fine, using Outlook web app also works. It only seems to effect those that use a VPN to connect to our network.
Just looking for anything I can try to resolve it
