Teams cannot commuicate to Skype personal after upgrade. How to rollback to Skype for Business?

Occasional Visitor

After upgrading from Skype for Business to Teams, the pre-existing external Skype users (personal) cannot be communicated anymore.  It's now affecting our business.

1) Is it possible to use Teams to communicate to external Skype user (personal)?

2) How to rollback to Skype for Business?

normally you should be able to use teams to chat with externals. But you need to readd the people you previously contacted with skype.

with powershell you should be able to set the mode you want to work in:



AFAIK you can't communicate with personal Skype users from Teams.. This was on the roadmap but was later cancelled


You could change your co-existance mode with powershell and via the teams and skype admin portal


If it is personal as in outlook you are right if it is personal as in another office365 organisation you should be able to do it.

Another blog about externals in skype



I found this setting in a client's Teams admin console today.




@Craig Arnoldt 

I have this setting too but we are still unable to chat with skype Consumers

Skype Consumer is not supported in Microsoft Teams. This is just a new topic that has gone from rejected to Thinking about it status in User Voice.

@Craig Arnoldt that setting relates to Skype clients, not Teams currently.


@Sam_Sam Looks like your answers are finally on the horizon.  See the following link on the Office 365 road map.  Although i'm guessing the feature probably wont be available until the end of this month....assuming they don't push the release date of this feature back...



This was placed in the Office Admin message center today.


 has shared this Office 365 message with you:


New Feature: Teams/Skype Consumer chat and calling interop


Your Teams and Skype for consumers users will soon be able to chat and make Voice over IP (VoIP) calls to one other.

  • We'll be gradually rolling this out the end of March 2020.
  • The rollout will be completed by the end of April.

This message is associated with Microsoft 365 Roadmap ID 53935


How does this affect me?


Teams users in your organization can chat with and call Skype users by using their email address and vice versa.


What do I need to do to prepare for this change?


Teams-Skype interoperability is disabled by default.

Admins who wish to enable this feature will need to go to Microsoft 365 admin center > External access and Enable users to communicate with Skype users.



You might also consider updating your user training and notifying your help desk.

We have the option enabled in Teams Admin (for a few days) but it doesn't appear to work for us.


Tried from both directions, Skype Consumer to Teams and Teams to Skype Consumer.


In Skype Consumer it just comes back and says the other person isn't online, and in Teams you type in the external email address and it is very hit and miss whether it shows the "search externally" option. You have to keep deleting and typing the last few characters of the domain name and eventually it will show the option. Once it does show the option, you click Search Externally and nothing happens, no message, no error.


This is not yet pushed to production. Next Month I believe roadmap said.
