Limit size of EDB, stm file in Exchange 2000 Ent.???

Dear all,

We have an Exchange 2000 Ent server which mailbox store houses 130 employee.
We set mailbox limit to 1.5GB. We've using Mailbox Item Delete Retention
for years.
(but not using Delete Retention for Public Folder), we currently now have:

1. priv.edb = 105GB
2. priv.stm = 51GB
3. pub1.edb = 31GB
4. pub1.stm = 608MB

Our backup runtime is about 4h to backup this mailbox store, and restore is
around 4h30

So the backup/restoration time length are still acceptable per our guide
line, however my
concern is how big we can say "enough" for these edb, stm file? Our physical
storage is
1TB for this mailbox store.

(In future, we plan to split users on the 1st mailbox store to 2nd mailbox
store or 3rd mailbox
store in order prevent the aggressive growth of the db files)

Regards,
J.H

Hi,

The size limit for these databases are much bigger than what you storage can
accomodate - several TB's.

I would recommend that you started splitting the databases into several
stores ASAP. This would decrease the restore time the a more user friendly
value.

Thanks for your response Leif.

Will it be more difficult when we have multiple mailbox stores in a storage
group and
trying to perform off-line defragmentation (since multiple mailbox stores in
a storage group
sharing a checkpoint file)?

Regards,
J.H

Hi,

If I remember correctly the best practice in Exchange 2000 was to create new
storage groups and then start with one mailbox store in each new storage
group. If that was not enough one would then create a second mailbox store
per storage group. In Exchange 2003 the recommendation is to create one
storage group, fill this group with all possible databases before creating a
new storage group.

mailbox store stops due to size - how to reduce I have a store that has grown too large and cannot get it running long enough to clean out mailboxes. I have done the reg hack to allow for a 17G mailbox size and ran an offline defrag and nieither worked. The defrag ran for twelve hours then failed. I

IS size limit I'm running Exchange server 2000 on Windows Server 2000. I understand the size limit for the IS is 16 GB and I am getting very close to that. I don't want to force people to copy important company emails to a PST that would be harder to back up. I'm wonde
