Outlook user with 13 shared mailboxes open in profile


Outlook version

Exchange Server
Hi all,

I have an Outlook 2010 user (mailbox on Exchange 2010) who has 13 additional shared mailboxes open in their email profile besides their default mailbox. This user is complaining that they don't see new messages arriving in these shared mailboxes and have to manually send/receive to see new messages in those mailboxes.

I suspect this has something to do with the sheer number of open mailboxes but I was wondering if anybody has any tips on troubleshooting/working around this? If I have to tell this user that it's because of the number of open mailboxes then I suspect that any kind of article/public document would be very helpful too.

Thank you,

Diane Poremsky

Are they all Exchange mailboxes? Are they added as accounts or as shared/managed mailboxes? He won't get desktop alerts for shared mailboxes, but opening the folder should show the new mail, he shouldn't need to use Send and Receive.
