Exchange 2013 licensing question.

Exchange 2013, there will 500 users. Not all 500 will login at the same time, three shifts here - the largest shift is 300 users. Can we do "per user" license of 300 since there will never be more than 300 concurrent connections or do we have to do the full 500 since there will be 500 accounts?

There will be some mobile phones, tablets and laptops for each account.

I agree with Sembee that you should ask twice and get it in writing but Disagree that the most expensive is the correct one.

As PeteLong said, you will need 500 Client Access Licenses.

A Standard CAL is required for each user or device connecting to Exchange 2013.
An Enterprise CAL is required for the advanced features such as Unified Communications.

Each user who is using an Enterprise CAL must also be using a Standard CAL i.e. you need both CALs for that user.

If you plan to do some advanced features with ActiveSync you may need Enterprise CALs for that.

You may need more CALs for the extra Tablets/mobiles. Ask your vendor to organise a call with a licensing rep from Microsoft to nail down your exact requirement.
