I am experiencing issues intermittently with screen sharing.  During a call when I am sharing my screen, users frequently report that the screen has frozen and they are no longer able to see my updates.  The screen is still being shared on my end (i.e. red box around screen) and screen share icon still showing screen being shared, but it won't recover.  I have to stop the screen share and start again.  Often I have to change to Skype for Business where it always works.  

 

The issues is not specific to me, I also have users who report the same problem from various locations.  We have checked into connectivity and bandwidth issues, but cannot see an issue.  I am able to use any other screen sharing service without issue (i.e. Skype for Business, GotoMeeting, Webex, etc.).  Issue is specific to Teams.

 

Anyone have an idea?

Thanks

I've had a few reports with video doing the same, maybe even screen sharing haven't gotten the report back from my support guys. I've been trying to get a call date/time so I can run through the call analytics on the new Teams admin for the call to see if it shows anything there. But can say we are getting some reports.

My screen share on Teams (sharing desktop) has frozen or never fully rendered for viewers for the past month.  I have used this extensively for months previously with no issues whatsoever with screenshare.  Experience on the viewers' side has been:

- Screen share freeze occurs within 30 seconds from when I start sharing

- Screen share is blurry and never comes into focus

- Some experience screen share where mouse movement is seen, but if I scroll down on a Google Chrome browser window, they do not see the scroll.

 

I have pulled most recent updates as well as uninstalled/reinstalled MS Teams to ensure I have the latest application to no avail

 

Any help would be appreciated as I use this feature very often.

We tried using Team meeting today for the first time and 7 people on the meeting, two were consistently having issues with the screen not keeping up with what the presenter was presenting. Those two were in the same office as 4 others who did not have this issue. Others have similar problems but less consistently. 

 

If this is not resolved, it could affect pickup of this technology in our company.

Please log these with Microsoft support through your admin centre, you won't be getting detailed support through this forum. I would also start checking that there isn't anything that might be limiting your network connection, like a firewall with only some of the required ports available. Try using the Network assessment tool (it support both Teams and Skype) ...

LOL--- Tried support through the admin center and got a call back from a 1st level who said...paraphrasing...
Tech: yeah, there are problems with that that we know about. 

Me: is there a ticket or problem number where I can find the status?

Tech: no, but you can go on UserVoice and put something there.

Me: so there is no one there that can help me with troubleshooting or resolving this.

Tech: no, this is first level support and we can't do that.

Me: so can you transfer me to 2nd level or someone that can actually help

Tech: no, they wouldn't take the call

 

 

 

This continues to be an ongoing issue for random users (occasionally at specific locations) at my organization.  Either they get a black screen, or the share will freeze up as someone is scrolling through, say, an Excel spreadsheet.  Reverting to RDP is not an option since VBSS is, well, amazing.

 

I had a chat with some of my network guys, and they found at one of the sites that the "burst traffic" setting on the network wasn't handling the UDP screen sharing, which kindof makes sense based on the behavior.  In those cases, once UDP loses sync, it never catches up.  They adjusted that setting and the users in that location stopped having the issue.  But now I'm hearing it's happening to them in that same location again.

 

Edit:  Just noticed this is for Teams - it's happening to us in SfB.  I was hoping that moving to Teams would fix it, but apparently not.  :(
