I have a GroupWise environment and have been asked put on a project to migrate to Exchange 2003. I cannot seem to find any information on disk space requirements for the database and transaction log sizing for any size environment.

I have 2500 users and we average 30 inbound and 20 outbound per user per day. We use SAN so disk space is not an issue I just need to know how many GB to allocate for each drive.

Thanks for any help.

I work on the basis of the mailbox quota size you are going to allocate to users. For example, if the quota size is 50MB max per user then you need at most 50MB x 2500 = 125,000 MB or 125 GB max for the databases and about 10% of that for the transaction logs.

I like your math on this but sounds to easy. I can't understand why Microsoft did not put this in their docs. You are the first person to come up with an easy answer to to a difficult problem.

What about the recover drive? If you need to restore mailboxes and or datastores what I shoudl do about space?

It depends on how likely you need to use this feature. In any sizing exercise you really need as much space allocated as you can afford and need to take in consideration future expansion such as more staff or larger quotas etc.
