Running exchange 2010 with half my users on Entourage WSE and the other half on a mix of outlook 2003/2007.
Some of the outlook users are unable to see the free/busy information for ANY entourage user. Some of the outlook users are able to see the free/busy information for ALL of the entourage users.
I suspected it was a problem with outlook 2003 and I started moving those folks over to outlook 2007 only to find the problem still persists. However, they are able to see free/busy from the OWA.
If I have one of the users who cannot see the free/busy info log into the machine of one of the users who can, then all of a sudden they can see the information.
So, anyone have any ideas?
