Hi,

We have a client using Hosted Exchange 2010 email platform. They have one mailbox which multiple users have access to helpdesk@....

Recently, the mailbox disconnected randomly on different machines at different times. The Host came back to say they have hit the limit on connections they can have to 1 mailbox at once (32)

They have about 10 devices connected using Outlook and thats it. I sent the connection status (Right click Outlook icon whilst holding CTRL - Connection status) which showed 5 separate connections to helpdesk@ on one machine.

Can anyone tell me what these connections represent and do these count as 5 RCP connections to the mailbox as the numbers dont really add up if what our host is saying is true.

Hi Ryank85,

Yes, there would be atleast 4-5 connections to your mail server from a single workstation; however the number of connections may increase based on other Outlook Add-ins or other shared mailboxes.

You can request your hosted service provider to use https://technet.microsoft.com/en-us/library/dd876852(v=exchg.160).aspx and see how many connections are connected to a particular mailbox.

You can also place an request to setup new throttelling policy for your shared/helpdesk mailbox so that it can have optimum number of connections https://technet.microsoft.com/en-us/library/jj863577(v=exchg.160).aspx
