We have a newly implemented exchange 2010 SP1 environment.
2 x exch mailbox roles (DAG)
2 x exch CAS / HT on NLB cluster
We currently have 4 mailboxes residing on the server during the testing phase, everything is working as expected aside from when two of the four users try to use the scheduling assistant within outlook (both 2007 and 2010). These users get the message "no free/busy information could be retrieved. Your server location could not be determined. Contact your administrator".
However, the two other accounts on this server can access the scheduling assistant. These two accounts hold the exchange organization admin role.
I'm hoping its a simple matter of reconfiguring permissions somewhere, but would greatly appreciate some help.
