Using Teams to Replace Skype


Hi There, 


I am having trouble figuring out how to use Teams as my only client and shut down Skype. I know that if I do not have Skype running I will get the notifications in Teams. But I only want 1 client. 


So my first big question is how do I send a message to a Skype user from Teams?

I am getting some private messages basically implying people don't believe me when I say external access is half-turned-on :)






UPDATE: Microsoft Product Group contacted me on this. It was a small mistake. It only impacts users that were in Azure AD already, not "new" external guest users. It still fails, but it seems this will be fixed soon.


@Josh SullinsTeams is built on groups, groups allow guest access, that's what you are seeing and has been there since the start. It's useful to know that when uploading a file using Teams that this might be seen by a guest accessing SharePoint.


Guest access to Teams conversation is coming, it's been talked about on the roadmap for a long time, and I'm sure we'll get all the details about it at Ignite.



You are right @Steven Collier, but this morning we got a message in all our Teams based on O365 Groups that already had externals in them, that the externals were added in the Team. So, I think something happened today, maybe it was possible before, and it is a little bug, but the message was an issue.


Again, MS PG contacted me (appreciated) and I know it will be addressed.

Yes, I have seen this in a couple of tenants so it seems Microsoft is already rolling out something...I was worried about the fact that external users had already access to my Teams, but I checked that's not the case...I hope they release both private channels and external guests support at the same time or at least provide granular controls for guests users at the Team Level
What is the most appropriate response now that it has been announced the teams will "take over" for S4B? I heard that we will be setting up and taking phone calls using Skype but am not sure where info is for the path forward. I also read that there will be the ability to call in via regular phone (without needing special PBX PSTN add-ons). Any news?

Well worth checking the FAQ, along with the other resources, if you haven't seen it yet.  It mentions, amongst other things, Inbound and outbound calls to PSTN numbers, as well as basic calling features (hold, call transfer, speed dial, voicemail) are to be added plus support for USB & IP phone hardware.  Also, audio conferencing is being added to Microsoft Teams.  There is a roadmap update due in October for Teams, that might add some further clarity.

Please , Do not hold your breath waiting on clear details. I think the automatic enabling caught a lot of Admins by surprise. I have turned off Teams until we can determine how the interaction with Groups, SharePoint, OneDrive are securely managed. We already had lots of problems with people creating custom share invitations breaking our SharePoint security.

I am following and advising customer UC and/or Microsoft since the OCS days.


For me Skype is going from a majority of 1-1 communications with easy escalations to a group. Now there is teams which is focussed on (larger) groups.


I know there is a roadmap to take all Skype online functionalities towards teams, which will take plus one year and not even the more advance communications will be included.


I am afraid of the following: items not working anymore between Teams and Skype for Business (federation, videoconferencing, desktopsharing, file transfer etc). A lot of investment need to be made into adoption of a new client.


Less support of Skype for Business 2019. If i look at the roadmap announcement at Ignite, only items i see is removal of silverlight and some connection to O365 dashboards. I am just not getting why trying to port a 13 years product towards something completely new (1year). Too difficult to manage Skype Online??


I know there is room for team communications. Funny part is that persistant chat never took off on Lync 2010/2013 and Skype. It was supposed to be used in the financial area, but my last customer was an international bank and they did not use it.  


If I look at my majority of clients with 5000+ users they should stay on Skype for Business On-premise or actually in most of the cases still in the proces of migrating away from the old PBX-es, Analogue connections, PZI integrations, Video integrations, Contact Center integration, Voice recording etc. All those items are already difficult for Skype On-Premise, impossible for people going to the Cloud. Why even consider Hybrids. So Microsoft is focusing on their Cloud-First initiative because it's in their benefit, I see little benefit for the customers (note: just the Skype for Business workload, the rest is has a better business case).


In the meantime Microsoft should deliver on their cloud roadmap and also fully invest in the On-Premise product. Otherwise there will be an opportunity again for Cisco, Avaya, Mitel etc. to take over again in the UC space. Cisco has already passed Microsoft in the Gartner MQ for UC.


It seems we have nothing to use right now. I cant even use Skype?? There's no way to setup video calls in teams? All of the people I work with have their own emails outside of the organization. I need to have meetings with people outside of the organization. I hope Microsoft's Teams becomes Skype or a "GoToMeeting" service for anyone (outside organization or in)!


Joseph, this is an old thread, Teams now supports both guests and people joining individual meetings who are anonymous. If you've turned on the ability to use Teams for meetings you can create a meeting in a channel, or schedule one through outlook.


Your guests can join using Edge for a full video experience, Chrome for audio and screen only, or install the Teams desktop app on Mac or PC for full experience (no need to log in for he anonymous join to work).


If you invite them to your channel they can log in using their email as a Microsoft Account, then join your chats, file sharing and meetings as well.


We are using both Skype and Teams, I have had no issues with Teams , even with conferencing both audio and video. Most of these are with external people. I have Teams set up for various projects and include the third parties in them so everybody is kept up to date and have to say, the video conference part is far superior than any I had used before. Even the mix of some video and some audio(usually because they have poor internet connection) works very well


Just picking up on this thread.


I too want to shutdown the use of Skype For Business in my organisation and move to Teams exclusively.


However, during testing I have not been able to get the SFB client to join a meeting organised by a MS Teams user and vice versa.


At the backend, the I set co-existence to Islands mode but I still have no joy.


By the way, with OWA, are there plans to update the SFB icon with the Teams one at some point?




You must use Skype to join Skype Meetings and Teams to join Teams Meetings. With Islands mode the two solutions run totally independent. When you go Teams only mode the interop improves, but not for Meetings.


For us, we will move the org to Teams only and keep the Skype client on the PC just to join meetings that were created in Skype (all our execs have their meetings planned 3-15 months in advance...). At the end of 2019 we will remove Skype from the PC.


Hi Josh,


I really appreciate the response. 


Another reason I want to move off SFB is that the client does not play well with Office 2013 installed, hence the pure Teams route.


I did open a ticket with MS, but they advised that there would be no issues using a disparite client in a meeting but obviously this does not work.


Sounds like there is no getting out of using SFB when the organiser has instigated it in this format.



It is a challenging situation. We are using Skype in conjunction with Office 2010. It is not an ideal situation.


I have asked Microsoft for a feature that lets a user CONVERT their Skype meetings into Teams Meetings when they are upgraded to Teams Only.


Right, one more thing.


For your Office 2010 client PCs, did you end up using the Basic SFB or 2016 SFB client?




We are already in the process to move Lync 2013 on premise users to Skype for business online.

Now the question is that can i just move the users to SFB online first from on premise then i can move them to Teams later on.What would be the good approach?as i can already see teams and Skype for business are together in O365 Admin center.



Not trying to be snarky, but someone might want to inform Microsoft about this. From their documentation:


"As an existing Skype for Business customer, you’re invited to upgrade to Microsoft Teams, to experience this full suite of communication and collaboration capabilities in a single client experience."

Not sure if this will be relevant at this stage but we have built a Microsoft-certified Cloud Connector that delivers voice services for Teams calling directly to the O365 Tenant. Our geo-redundant solution also completes the missing PBX and legacy feature-set, provides full integration capabilities to Call/Contact Centers and CRMs and handles extension dialing, DID /TF number porting, as we are a Tier1 Cloud UC carrier. Our cloud dial-plan allows for legacy PBX or Skype4B to Teams extension dialing during migration as well.
