I waited for the 5.0 OTA for my Nexus 5 and anxiously upgraded last night. Suddenly my Exchange calendar items were missing and I didn't even have the calendar in my viewable list.
Account settings showed a sync error on the calendar. Couldn't establish connection with the server.
I tried deleting my Exchange account and re-add it. But now I get the same "Connection" error message and I cannot complete the wizard.
Anyone else's Exchange sync busted since going to 5.0 official release?
