Dear All,

We are currently running HP Openmail with MS Mail as our email system
and are looking at migrating to Outlook 98/Exchange 5.5.  We will have
about 2500 registered users and up to 1500 concurrent.

I would like to make contact with anybody who has a similar (or larger)
Exchange environment succesfully running on a single box (we plan to
use HP Netserver).  If anybody has any practical experience on how many
users a single box can support that would also be useful.

Why post on ADSM list?  Well it is a useful method & I know there are
many Exchange users out there.  We plan to use ADSM Connect agent for
Exchange and anticipate about 100GB of central storage.  We already use
ADSM V3 backing up about 1.5 TB of data (R40, AIX 4.2.1, 3494 with 2
3590 drives).

Any horror stories would also be useful!

Appreciate any feedback.  Please respond directly to me and if anything
interesting for this list crops up I will summarise and repost.

Regards,
Simon
