Hello I am currently running microsoft exchange 2010 service pack 1. We have configured active sync and for the most part is working on all of our mail accounts that have access to mobile phones. When I go into the mobile device console, I usually see the phone or mobile device the person is using to connect to the mailbox. However ,on one of the accounts, when I choose the mobile device option it doesnt show any device connected in the mobile device window and the person cannot sync from there iphone to the mailbox. The phone starts a sync with the account but disconnects and does not allow the phone to synce. This is only happening to this exchange mailbox account. Is there anything I can look at on there account to see why they cannot connect. We setup a test account and the phone was able to connect to the test mailbox. Thanksvisualbasicfrustrated

I enabled the security inheritance feature and it still does not work. The account is also not a part of any protected group. The accounts primary group is "domain users". In fact some accounts do not have that inheritance feature checked and they can still sync there account.visualbasicfrustrated
