Outlook 2011 on MAC – issues with Imap, when multiple users log in we are constantly being asked to re-enter the passwords and keep getting logged out.

Hi Guys,

For the last 4 years I have run several mailboxes through Outlook using IMAP settings, some of these mail boxes are monitored by more than 1 person at any given time.

I recently upgraded all the computers to mac's and since then have had nothing but issues.

The emails keep dropping out and asking us to log in and re-enter our passwords relentlessly,

We also keep finding that when one machine is logged in it knocks another off, we are finding it really difficult to get any thing done:

The error message we are getting the most is this:

The server for account returned the error "[UNAVAILABLE] Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10)." Your username/password or security settings may be incorrect. Would you like to try re-entering your password?

This seems bazaar as the mailbox with the most connections would never exceed 5/6 and some mailboxes affected nobly have 1 or 2 connections,

I have tried to call Microsoft, raised the issue with my email host and have spoken to Apple, as yet i have got nowhere to finding a solution.

Please advise.
