Mailbox size in Exchange 2007

I have a user who continues to ask each new Executive Director or person I report to that I increase his mailbox size from 2.38 gigs to at least 5 or 10gigs of allotted space. I believe there were space limitations in the past with older Exchange but am having an issue finding space reccomendations for e-mail boxes for Exchange accounts. Google says that their solution is '25 times the industry standard' so I don't think I'm off with a 2.38 gig allottement.

Is there danger to allowing him more? Can it corrupt his e-mail account, the mail store at large? Any data to back me up would be great - we're an office of 35 and everyone else is fine with the allotment.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It will make outlook slower.  Considerably slower.  And there is a higher risk for mailbox corruption.  Especially if he has a remote device configured to sync email, contacts, and calendars.

You can probably do it, but make sure he knows that he is exposing himself to more risk and hassle.  It may take you a few hours to fix his mailbox when it breaks.  He'd be way better off archiving old mail.

(Also, take a peek and see if he has 1.5gb of family vacation photos that he emailed himself.  That would deflate his argument pretty quickly.)

I wouldn't increase the mailbox size limit unless you have to. You might want to consider an archiving solution if this problem gets worse and more and more users want larger mailboxes.
