Basically got a new Exchange 2003 server up and running so that makes two. Intending to migrate all the mailboxes over and remove the old server as its just has old hardware and all that.
So everything seems to be going well BUT … the Free/Busy data seems to be only replicating one-way.
The test user on the new mail server CAN see all other staff members free/busy data when booking them for a meeting or whatever but other staff CANNOT see the test users free busy. The Test users Freebusy data isn’t hashed out though (as in cannot access free/busy etc etc) it is just clear… showing no meeting when there are in fact meetings there.
