We're experiencing an odd issue, specific to free/busy information being unavailable in Outlook and OWA for select mailboxes. Our environment:
All Exchange 2010:
Site1: 3 Mailbox Servers (mailbox database mounted on each server), 2 HT Servers, 3 CA Servers
Site2: 2 Mailbox Servers (mailbox database mounted on one server, the second server maintains only database copies), 2 HT Servers, 3 CA Servers
Bearing in mind that all configurations have been validated to be correct (at least what I have seen) and that free/busy was working, here's the scenario with which we're faced. Free/Busy info on all mailboxes on any mailbox databasein Site1 is available. Free/Busy info on all mailboxes on the database mountedin Site2 is unavailable in Outlook or in OWA. Remember, this was working previously. As a test, I went as far as moving the mailboxes in question to a database in Site1, free/busy information then became
available.
After an extensive search I found that any free/busy issue out there was either only related to Outlook or only related to OWA. In our case, free/busy isunavailable in both Outlook and OWA for any mailbox mounted in Site2. I have found a viable solution (link below), but this only works if the end-user or admin runs through the steps on the client machine itself. Clearly, I can't ask end-users to run through the steps without being on the receiving end of some backlash and/or expect them to run through the steps correctly.
Can someone offer some advice?
