For some reason, my contacts/calendar are not syncing after the recent update. In my settings, I have the account set to sync contacts and calendar, however, under the "Accounts and Sync" section, my exchange account says "Sync is OFF" and I cannot change this. I have gone into the "Account Settings" for this account multiple times to confirm that the box is checked for sync contacts/calendar, and it is checked. I am getting very frustrated! Email works just fine.
