I'm having a very strange issue that some users are unable to view Free/Busy of any other user and mail tips don't seem to work for everyone either. I'm not sure if these issues are related but just putting them both out there.
We're currently running an Exchange 2013 Standard Edition on Windows Server 2012 and the clients are all running Outlook 2010
Any suggestions on going about troubleshooting this would be great,
I found a good article about a similar issue but the resolution was shown using Exchange 2010 but 2013 has a considerably different interface..
Hope someone could assist.
