Do resource accounts use up CALs (on Windows Server 2003 AD)?

Posted on 2008-10-14

We were going to use them instead of public folders just to help end users avoid the tedium of Folder List, scroll all the way down, expand [+] All Public Folders, look for the right one and open it from the Nav Pane, only to have to go back to Mail or Calendar mode where they normally work every single time they need to use a public folder. It's much easier to have an always-handy checkbox in your list in the Navigation Pane

However I read somewhere that each resource account takes up one CAL. Does that mean if we have 100 cals, and there are 30 resource accounts, that only 70 people can log in at a time?

Well, my real question is simply if resource accounts use up licenses or not. Any official documentation stating such would be a HUGE help

I think its 'per user' not 'per resource' for exchange.

So no your resource mailboxes wouldn't take CALs

per seat/user is explained 1/2 way down and it says those are expectable licensing models for exchange.

It depends how it's used.

If the mailbox is shared between licensed users then no additional CAL is required (because no additional user is connecting to the system). If it is used by a third-party system and not shared then a CAL is required.

This is the best article I found for client access licensing, it's actually moderately clear about what's needed:

You can log in as the conference room as well, as long as it isn't accessed by someone or something that isn't covered by a license.

You could have a hundred user accounts and mailboxes and only one user and you would still be licensed if you had a single CAL provided that the user (as a person) is the only one accessing each (which is quite impractical).

Yes, if you access the service as a user you must have a license. It doesn't matter what the user accesses if they're licensed.
