I agree with Jason. You'll need the Enterprise version for stores larger then 75GB, or since your end users are either using IMAP or POP3 and selecting to save the mail on the server, it's best to just drag their mail to a local PST and then reconfigure the Outlook client for MAPI mode to the new Exchange server. With only 45 users, SBS Premium edition is a good value and can grow to 75 users. Also I would just tell your Mail clients that all their mail prior to the mail server migration will remain local and all new mail will be accessible on the server. It doesn't sound like you were using a group ware solution for Calendaring so your free and busy information should not have to be imported.

It is also limited to 75GB. I don't recall if this is a total limit or 75GB for mailbox and another 75 for the public folder store. To support more DBs and over 75GB you will need the enterprise edition of Exchange. I highly suggest you limit what data you migration over from the Linux system, having an average mailbox size of 4.4GB is absurd! To support this amount of data is going to require good planning for backup/restore, DR, and for your storage system. While there is no "hard" limit to mailbox size in Exchange the general recommendation is 200MB/user. If users are working in cached mode in Outlook their entire (4GB+ mailbox in your case) in stored locally in a OST file. If Outlook crashed or a user just shuts off their machine it will take a VERY LONG time to check this file for errors, which cannot be skipped, the next time Outlook starts up. In addition, any type of desktop search software (Lookout, Google, MSN, etc) will put a big load on the server as it tries to index this amount of mail. If most of the space is due to attachments then get them out of your mail system and store them in SharePoint or a file share.
