Hey We have a special requirement. A customer want to use outlook to as a scheduling tool for their 5000 "candidates". The employees must be able to book meetings, add vacations etc. to these users to provide a effective and unified scheduling using outlook experience. The thing is - these external users / candidates will never be accessing their account, getting notifications or anyother interaction with their AD account in exchange - the account is purely needed as a effective planing tool. Obviously buying 5000 CAL for this is not reasonable. Buying external connector license (though im not sure where this is needed for all servers AD/DC/Exchange) might be an option - but is this necessary in our scenario? Do we even need any kind of CAL when no users is using the account? Best regards Anders Reinholdt

Hi Anders, This isn't the best place for licensing discussions as most of us aren't qualified to talk about your specific licensing agreements or the interpretation Microsoft might have. If you want to create mailboxes for these users Exchange's tools will show these in the reports it can generate which would indicate you would need CALs.. However you may get something in writing from Microsoft Licensing or your licensing vendor to say otherwise. As another option, though, would the use of Mail Contacts work? This would allow the appointments to show in the employee's calendars (or shared calendars perhaps) and associate the candidates email address, if required, with the mail contact.

Agree with Steve. Suggest you call Microsoft representative about license directly. Exchange Server Licensing http://www.microsoft.com/exchange/en-us/licensing-exchange-server-email.aspx Frank Wang
