The free/busy availability services roars it's ugly head again !
When clients are inside of the firewall, free/busy and suggestions inside of Outlook work. When clients go outside, the availability information is being retrieved (I see that someone is available or not) but suggestions cannot be provided because free/busy data could not be retrieved (I SEE the data being retrieved for crying out loud !).
Now even the remote connectivity analyzer tests all report success, so I have no idea what to do now. The only thing left is blame forefront TMG, although I run this exact same setup for another few companies with the same TMG setup and here it does work correctly.
What is especially mindbreaking is the fact that free/busy information is being picked up, (I can see people's availability inside the planner), it is just that suggested times is not working. No idea why this one claims it can't retrieve data as it is clear that data is being picked up ?
Now as I said, all the remote connectivity analyzer test report success (including Synchronization, Notification, Availability, and Automatic Replies test) I clearly see data being retrieved, yet the client still won't load suggestions, is this functionality
looking at something else ?
