Sharing an Excel spreadsheet under the Window heading is problematic. On the receiving end it sometimes displays as blank(white) or just a static image where participants cant see any activity like scrolling, highlighting a cell, etc. It works fine when sharing through the Desktop heading, but sharing the application (Window) itself presents the issues above.

Windows10 Enterprise
Ms Teams 1.3.00.15561(64bit)
IE and Goggle Chrome
HP Elitebook

I've already cleared those Teams cache folders under %appdata%. Also performed a re-install of Ms Teams. The Excel files are small, still KB's in size. I once tried sharing an IE browser and it was the same, so i think IE is also affected.

Please help?

Kindly,

I have Office365 Business Premium and I am using Microsoft Teams for educational work. During Teams meetings, I share my screen & give control to my pupils, so they can manipulate the application and type answers to questions (e.g. in Powerpoint).
I live in Belgium and my keyboard layout is Dutch (Belgium), the letters on the keyboard start as AZERTY.
During the "give control" screen sharing session, when the team member types (remotely from his PC), the keyboard layout is always incorrectly interpreted as English, thus an A becomes a Q, the Z becomes W, etc (QWERTY instead of AZERTY). This is very disturbing for my pupils and myself and distorts the user experience.
I have tried different methods of resolution, such as changing the option 'keyboard language overrides keyboard shortcuts' on the other user's Teams client to France, but that doesn't change anything (there are limited choices in that pick list); when the other user types A this is interpreted as Q.
I have also logged in to the Sharepoint Online associated with my Office 365 and I have set the default language there to Dutch (Belgium) with no effect.
I am using the latest version of Teams on iMac with MacOS 10.13.6 (High Sierra). My pupils are using the Windows version of the Teams client (Win 10 or Win 7).
How can this be resolved? Please help.

I have a large(ish) Team of 172 members and have at least a dozen instances of people telling me that they are getting notifications of new posts even though they have the channel notifications turned off or even have the channel itself hidden. I have verified that they have their notifications set to Off for "All new posts" and/or that they do indeed have the channel(s) hidden. They still get banner and Activity Feed notifications whenever there is a new post, even without any mentions at all.

I have provided a couple of screenshots to demonstrate. One is of the channel setting showing that the "All new posts" is Off. The other shows a notification in the Activity Feed for a post that was a reply in that channel to a post that I did not create.

We have probably around 100 Teams created and this only seems to happen in Teams that are large. I have gone so far as to create a brand new Team with a slightly different name and add the same members back in, essentially "re-creating" the Team with a brand new setup (hence the different name). That did not fix the issue either, although it affected different people after I created the new one. Some people have the issue in both Teams, some were fixed in the second one, some didn't start having the issue until the second one. This happens when using the Desktop App, the Web App, or the Mobile App so this definitely appears to be a bug on the backend rather than a client configuration.

I have performed the following steps in an attempt to troubleshoot:
1. Setting Notifications for the channel back to On, waiting about 10 minutes, changing them back to off.
2. Manually logging user out of Teams then logging back in.
3. Uninstalled/reinstalled the Teams desktop app.
4. Uninstalled Teams Desktop app, deleted the following folders manually, rebooted PC, then reinstalled Teams:

 a. "C:\Users\<user>\AppData\Local\Microsoft\Teams"

 b. "C:\Users\<user>\AppData\Local\Microsoft\TeamsMeetingAddin"

 c. "C:\Users\<user>\AppData\Local\Microsoft\TeamsPresenceAddin"

 d. "C:\Users\<user>\AppData\Roaming\Microsoft Teams"

 e. "C:\Users\<user>\AppData\Roaming\Microsoft\Teams"

Alas, nothing has worked.

Using https://www.poshtestgallery.com/packages/MicrosoftTeams/1.0.21 when I try and use the following command Add-TeamChannelUser -GroupId $groupid -DisplayName $displayname -User $username -Role Owner

I get the following error message

add-TeamChannelUser : Error occurred while executing

However if I use the GUI I can add owners to a private channel. This means that I cannot script adding channel owners but rather must add each owner the slow way through the GUI.

This has already been reported here https://github.com/MicrosoftDocs/OfficeDocs-SkypeForBusiness/issues/3753 but that ticket was closed.
