Exchange CAL licensing

[yizhar]

HI.

As far as I know, Exchange Client Access Licenses are "Per Seat" which means that it counts how many client computers are running Outlook, but it does NOT matter how many users are using those computers, and it does NOT matter how many mailboxes are defined at the server.

This means that if for example I have 3 users that use the same computer but have 3 different profiles and mailboxes, all need a single Exchange CAL.
This also means that if I define at the server a resource mailbox (like meeting room), this does not need additional client.

However, many of my colleagues are insisting that the license count is by mailbox.

So I'm looking for the following:
* Am I right or wrong?
* Do you have a link/document from Microsoft that will answer those questions once and for all?
* Is it the same for Exchange 5.5 and Exchange 2000?
* What about OWA - does it need any CAL?
* What about POP3 & IMAP users?

I have visited the

http://www.microsoft.com/licensing

and did find some answers but not to all questions.

Thanks

Looks like from this document EACH mailbox needs a CAL. I'll be ordering more licenses tommorow...

HI.

I have read this article, and the phrase
"A CAL is required for each workstation or client device with authenticated access "
means that the device needs the CAL, not the mailbox - so in a typical 1 to 1 relation it is the same count, but the cound is for devices - i.e. client computers count.

This is what I understand.

The per seat licensing means that the connecting device needs the CAL so if you have 100 workstations you need 100 CALS. (If only the various license schemes were that easy)

Now does OWA require a single CAL? So if we have 20 users that only use OWA to access their mailboxes and 5 desktop clients running Outlook we would only require 6 CALs for Exchange 2000? Thank you,

Nope... 25.

This was actually on my certification test for 224.

CAL - Client Access License. OWA is a client so if users use it you need a CAL for each user. Dan

A CAL for each user or each machine in regards to OWA
