I have an issue with all my users not being able to set their OOO. They get an error message saying "your out of office settings cannot be displayed, because the server is currently unavailable. try again later".
This happens for all our users who use Outlook 2007, 2010 & Outlook 2011 for Mac even though all users can set their OOO using the OWA.
I used the testoutlookconnectivity tool which throws up no errors. I've even reset the Virtual Directories for EWS & Autodiscover.
Also after resetting the Virtual Directory for EWS I can no longer configure Outlook 2011 for any new users and also my current MAC users can no longer connect to the Exchange server.
I've also configured the internalurl & externalurl for each of the EWS & Autodiscover Virtual Directories, but still not luck.
Can anyone shed any light on what I am doing wrong or anything that I may have missed?
Your help is much appreciated.
