Exchange Server Access over WAN
Hi!
We are using Outlook2003 in Cache Mode to access our mailboxes, hosted on a
Exchange 2003 server. The connection is over a 1 Mbit/s WAN link, and without
Cache Mode, the performance is lame. Cache Mode covers this for the mailbox
folders. The real problem are the Public Folders, where thousands of
documents are stored. Caching them too, will produce gigs of cache on every
client and pulling their overall performance to the ground when searching
through the gigs of cache, especially on notebooks. We monitored the WAN
link, the line is not really busy, about 30% are used during the dayly work.
But searching through a few hundreds of messages stored in a public folder
freezes Outlook for several minutes! Has anyone a clue? The only thing i can
imagine, is a Exchange 2003 server in our office, holding only the Public
Folders our CO's employees have access to.

If you do have an enormous number of public folders and are working
cross-site I would have to suggest that an Exchange server be located
in the other building.
However, you don't have to have all the mailboxes there and you don't
necessarily need to backup the server as long as you're happy that
replication of additions on the remote server are replicated to the
main server where they are then backed up.
