It's time to migrate off of SBS2003 to isolate the domain controller and Exchange. I am looking for resources to size my environment.
Our Exchange 2003 mailbox store is around 62GB, for approx. 60 users, however, my goal is to absorb dozens of PSTs into the mailboxes.
Any suggestions on how to calculate this would be helpful. I am about to place an order for new storage and servers and I need to understand the requirements.
Thanks in advance,
