Unity Connection with Office 365

Hassan Alodaini

Level 1

Hello!
Our Cisco Unity is connected to Office 365 (Unified Messaging Integration), we used to get emails when someone left us a voice message, but it stopped a few weeks ago.
We got this error "Failed to locate a Domain Controller via DNS".
The Active Directory DNS Domain Name is correct: outlook.office365.com.
The username and password to the account to access Exchange is correct: username@domain.com, our office 365 license is still valid and we are subscribed to "exchange online (plan 2)"
Any ideas?

It seems unity connection is unable to find the server through DNS.

Try Specify an Exchange Server is selected instead of Search for Exchange Servers.

What type of authentication do you use for the O365 integration? If you use Basic that was deprecated by Microsoft on the 1:st of October. You’ll need to use OAuth2 for the authentication. There are quite a few posts about this in the community, recommend you to use the search option and read up on this.
