Helped a cohort out troubleshooting a new Unity Connection 11 and Office 365 Unified Messaging integration today. A couple quick notes to help you out:
- It's recommended to use Search for Hosted Exchange Servers.
- The Active Directory DNS Domain Name has been outlook .office365.com at the last few sites I've dealt with or deployed.
- The username to access Exchange must be in the username@domain.com format.
- As usual, Unity Connection errors can be misleading. Here we were being returned a "Searching the network Failed to locate a Domain Controller via DNS." error. Despite looking to be a network access or name resolution problem, it's actually a symptom of a bad password on the Exchange access account.
Good job, Cisco.
