Hey everyone,

I have a client who is using skype for business 2015 on premise server and there exchange is in Office 365. They been running on this for a few years now and no problems. All of a sudden then noticed that the voicemail is not working when call another user from skype to skype, but it is working when calling there direct number (DID).

Any ideas on what to look for or anyone with a similar issue.

thanks

Hi ageless40,

What do you do before this problem appearing?

Does everyone have the same problem?

In my research, Unified Messaging (UM) has been deprecated in Exchange 2019.

If you've deployed the UM role in Exchange 2013 or the UM service in Exchange 2016 and you want to upgrade to Exchange 2019, you'll need to migrate your voicemail to the Microsoft Cloud Voicemail service in Office 365.

For more information, please refer to:

https://docs.microsoft.com/en-us/skypeforbusiness/hybrid/plan-um-migration#exchange-2013exchange-2016-and-skype-for-business-2015-to-exchange-2019-and-skype-for-business-2019

Make sure that your client is the latest version.

In addition, please check if there any error event in Skype for Business server.

Best Regards,
Sharon Zhao
