To summarize, I am no longer able to sync messages from Exchange
2 Win 10 devices going to a GoDaddy hosted Exchange account
Both were working
Performed a clean install on my Surface Pro
Will not DL or sync email messages but empty folders show up
I have removed device registration using OWA/options and added account and reboot many times
I removed my account from second device and now that one will not sync
Active Sync test connectivity test is ok
Log from OWA shows the following
--- Exception start ---
Exception type: System.InvalidOperationException
Exception message: Operation is not valid due to the current state of the object.
Can anyone suggest additional steps I can take to resolve this issue? Outlook 2013 works fine from both devices but I need a more tablet friendly app on the Surface Pro.
