Need your help asap! We have an SBS 2008 box and the exchange 2007 is fully patched. We recently added a new user who has 2 mobile devices (iphone and iPad) as well as a laptop.
Both iPad and iPhone receive a message in mail app that they cannot connect to server. Whilst this happens calendar, contacts and sent items sync fine. Inbound/inbox does not sync however. If he removes the account and re-adds it, sometimes it will work for a while and then stop, and sometimes it will not work at all.
I thought i had cracked it as his user was occasionally appearing in the event log in the event "mapi session exceeded the maximum of 16". I adjusted this to 50 and no longer are receiving these events, however the user still has the syncing issue.
I have run the https://testconnectivity.microsoft.com/
and it didnt seem to come back with any issues.
Can anyone shed any light here?
