Hello all,

We are planning to change from MDaemon to an Exchange-server.

Can anyone tell me how big a single mailbox can be in Exchange 2003 and 2007 ?

There's a big possiblity we want for Exchange 2007 to come out, but I cann't
find anything about mailbox-size :-|

Greetings,
Jochen

Hi Max,
I think on a single mailbox you can set illimitate mailbox, but at
Information Store level from Exchange 2003 SP2 you have 75 GB of space.

That's 75Gig for ALL the users, not 75GB per user...

That's only for Exchange 2003 Standard.

Exchange 2003 Standard with SP2 = 1 75GB Mailbox Store (that could be one
user with a 75gb mailbox I suppose), and 1 75GB Public Folder Store
Exchange 2003 Enterprise = up to 20 total Stores per server, with each store
having unlimited capacity (limited only by hardware - theoretical limit of
16TB).
Exchange 2007 - I haven't seen what the distinctions will be yet, but at
least for Enterprise version = up to 50 Storage Groups, up to 50 Stores
total.

In any of the versions, mailbox size can be virtually unlimited - you are
limited only by the store size (in Standard), or by hardware (Enterprise).
As a practical matter though, mailboxes that are larger than a few GB
usually get unruly and you can start to have performance problems (with
Outlook).
