I am attempting to setup ActiveSync for Android\iphones and am experiencing a couple of issues. I have gone through the recommended setup and am able to connect to OWA (SSL\Forms based access required) and OMA through IE on a pc and on a mobile device.
I can add\verify the account but when attempting to sync it displays an error of "Cannot get mail. The connection to the server failed."
When I test the account through testexchangeconnectivity.com, I receive the following:
"An HTTP 401 Unauthorized response was received from the remote Unknown server. This is usually the result of an incorrect username or password. If you are attempting to log onto an Office 365 service, ensure you are using your full User Principal Name (UPN)."
Looking at the eventviewer, I see the following error:
Event ID: 3005
Unexpected Exchange mailbox Server error: Server: [sbserver.xxx.local] User: [email@example.com] HTTP status code: . Verify that the Exchange mailbox Server is working correctly.
Steps taken to troubleshoot:
1 - rebuilt IIS virtual directory
2 - Disable\renabled activesync in user account
3 - deleted\recreated MS Activesync in ESM
4 - Verified SMTP ExchangeVDir in registry.
and a number of items also that escape me at this point.
Any help is appreciated.
