After migrating from Exchange 2003 to Exchange 2010, when people with Outlook 2003 try to schedule an appointment, they see only free / busy information till the following month. So in august they saw information till october 1st. In september they see free / busy information till November 1st.
2 mailbox servers and 2 servers with hub transport role and one of them with CAS role.
Two mailbox databases configured in DAG. Two public folders, each one connected to a mailbox database. Replica's on both mailbox servers.
As far as I can tell the public folders are configured correctly, because there is free / busy information in there.
With Outlook 2010 / OWA there is no problem.
Is this "working as designed" and if not, how can change something to see more free / busy information in Outlook 2003?
