Hi,

Can some one let me know that what is the maximum number of concurrent connections in exchange server 2013 for a single user using outlook 2013?

Actually one of the client is using outlook 2013 with Exchange server 2013 and he wants to access his mailbox from more than 20 outlooks at the same time.

Regards,

Nawaz

How many connections does he want to make and why? 

The default I believe is 20 max connections. This can be changed by creating a throttling policy and applying it to that user.

To make things easier the Parameter you are looking for is RcaMaxConcurrency.

Thanks Hinte,

One more question.

What if a user connect from 4 different outlooks  with his single mailbox so it will be count 4 connections or more?
