SBS 2011 CALs when having 7 domain PCs + 30 mailbox only users


A SBS 2011 std and 7 PCs joined to domain and 7 user accounts for those PCs. I need 7 User CALs for those. Right?

The customer has also 30 private resellers who need to have RPC over HTTPS Outlook mailbox. I plan to create 30 additional user accounts for them. Do I need any CALs for those? Rather not. They may use also Smart Phones to access mails. They don't use malboxes simultaneously - rather time to time.

Ultimately I might implemet SharePoint Intranet for all 37 users but that is only a option.

Yes, the 30 additional accounts are being authenticated by the domain to gain access to the server resources.  Further, CALs are by HUMAN NAMED USERS, not account names - not sure if you meant it this way, but even if the 30 shared one single logon, you would STILL need 30 CALs.

I would also suggest you to contact microsoft licensing support team ,they will give you exact details about Number of CALS required.
SBS CALs are not concurrent and are based on user access. So you have 37 users you need 37 CALs.
SBS licensing is per user OR per device. Since all users log on (via Outlook or whatever) from different machines, per device licensing does not apply. You must purchase 37 user licenses

With the majority of accounts being outside of the local network, I would recommend to look at hosting all exchange users in the cloud. You could also consider a mixed model where the resellers have their own subdomain such as and host that in the cloud with the 7 users on being run on the SBS server.
