Mailbox quotas?

I’m curious to see what most companies standards are on mailbox size quotas.  Here at my workplace we have a 200 MB limit on mailboxes.  You can of course archive to your heart’s content, but once you go over 200 MB in your server based email file, you are effectively locked from sending out email.

For me, 200 MB is MORE than generous.  I cannot imagine why anyone would need more space than that, even if they dealt in large images and PowerPoints all day long.  My users act like we’re some kind of evil bastards for imposing the limit.  I just want to know what everyone else experiences.

What are your limits?  And how do your users react?  I’m really curious about this…
