Environment: Exchange Server 2003 (single server), Outlook XP & 2K3 clients

Issue: Nearly all of our users have their free/busy scheduling set to
publish the 2 month default, updating the server at 15 minutes intervals.
We've noticed two oddities -
  1. Outlook apparently considers the current month as "month 1,"
regardless of the current date. Therefore, if we're looking at a users
schedule on July 29th, we can still only see the schedule through August
31st, not through late September, as one would intuitively expect. Is this
behavior by design?
  2. As of 3PM on July 2nd, the schedules of at least two users in the
organization still only display through the end of July, even though their
free/busy schedule setting is at the 2 month default. I've verified that the
users have logged into the network and have been actively using their Outlook
clients today. Why is this happening?

Thanks for any imput!
