We've enabled MS Teams on our 365 business account and have been investigating its suitablility for communications between our teams. One of the features we're most interested in is the live video/audio calling.

 

When we schedule a meeting in a channel and then attempt to join we're having issues. Essentially, the only way for users to successfully connect is to click the "Join Microsoft Teams Online Meeting" text-based link in the meeting details pain. Clicking the main "Join online" button within this panel launches the meeting, but immediately kicks users out with no error message (just says "leaving" on screen).

 

Please see the attached screenshot for reference.

 

We're using the Windows app (32bit and 64bit) on both Windows 10 and Windows 7 machines. The behaviour is consistent across these desktops.

 

Has anyone experience this issue, and found a fix for this?

Thanks, Adam

escalated internally for investigation.. sorry about this!!

this is an issue on our end. working on rolling out a fix ASAP!! thanks for your patience.

the service fix has been rolled out to all customers and it requires a desktop client update that is being pushed out as well. If the issues persists after ~ 15 minutes please let us know on this thread. thanks again for your patience!!

It's fixed! I'm very impressed with the speed with which you addressed this. Thanks so much.

Is there a new build number to confirm?  When I click "About" in Teams this is what I see below.  Also when I check for updates it says this is the latest.

 

You have Microsoft Teams Version 0.7.00.403 (64-bit). It was last updated on 1/13/17.

Highlighted

That is the version I have.  You have Microsoft Teams Version 0.7.00.403 (64-bit)

Sorry about the confusion! Actually it required a client refresh (exit and sign back in) and the fix also inserted a logic for min version requirement check.

I can't connect to an ongoing meeting and I have already done everything you said.

Product: Teams
Issue: Not be able to join to an ongoing meeting,
Description: I click on Join, Its say connecting and after a few seconds says Leaving
OS: Windows 10 Enterprise
Teams Version 0.7.00.5203 (64-bit)

Any idea how to fix this issue?

I'm still having this same issue also.  We are consistently unable to use Meetings.  Strangely it does work inside the "Chat" pane with 1:1 meetings.  For reference I'm using build 0.7.00.5203 (64-bit) on Windows 7.

Highlighted

Meeting chats are different than 1:1 chat. In a 1:1 chat, media will flow dirrectly between clients as long as a firewall isn't blocking that trafffic. For meetings, all media flows through online infrastructure. If media flow cannot be established for meetings, this is due to network proxies and or firewalls blocking the traffic. Please see here for listing of FQDN's and IP's that must be accessible from network to connect to all Microsoft Teams services: https://support.office.com/en-us/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-ab....

Note that all IP's must be accessible in addition to required FQDN's.

Thanks Carolyn!  Just to clarify - I'm talking about VOIP calls in Teams where we see them consistently failing using the "meet now" or "scheduled" features but work fine when initiated from the "Chat" pane.  Note we also use Skype for Business in our organization and those meetings (whether scheduled or ad-hoc) work flawlessly.

 

Having said that would you still suspect the issue is on our firewall side?  We would have expected that if SFB scheduled meetings work then so should Teams and have assumed it is an issue with the beta nature of the product.  

 

Lastly are there any tools/utilities specifically for Teams that can scan and confirm the connectivity is correct?

Highlighted

You're welcome Ryan. Yes I understood you meant VOIP calls. When calling from Chat pane, that is typically a 1:1, or Peer to Peer call. When using Meet Now or a Scheduled meeting, you are connectin to the online Meeting Processors for the call. This is most definitely a firewall issue. Please take a look here https://support.office.com/en-us/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-ab... for Teams specific FQDN and IP addresses that must be accessible. 


Teams and Skype for Business have differences in how/where meetings are setup.

No there is no Teams specific tools and utilties available at this time.

I have one of the employees that I am working with who is receiving the same message when he is using the desktop based version.  We have him using 1.0.00.28451 x64 and on our company VPN.  In the meantime I'm also asking him to attempt to join his group/team meeting through teams.microsoft.com while we wait.  Let me know if there is anymore information that you would like me to get for your to properly investigate.

I had this issue only last night. While all other aspects of the desktop app are working, I couldn't join a meeting. No other participants experienced problems. I'm on an MS Surface Pro using Windows 10. I see that an update fix was posted last year but I'm guessing I'm running a current version or near to it.

I don't have a join button on my laptop. I had to switch to another computer and then the join button showed up. The only button I saw on my laptop was the team button with an eye emoji. Please help me as soon as possible. I need this for school.
