Hello Pierre,
Generally, sharing delay issue in meeting can be more related with network conditions. I recommend you confirm with let presenters as well as impacted participants about their network environment including connections, firewall and antivirus. If convenient,
you may try to change to a better network environment to hold and join meetings and perform sharing for test.
As far as I know, Teams client itself won’t block any meeting and sharing traffics, according to your issue symptom, I recommend you let presenters as well as impacted participants try to use Teams web app to see if issue exists. In the meantime, you may
let all impacted users try to clear caches:
Windows:
------------------------
Close Outlook and other apps that have integrated features with Teams, go to File Explorer and type %appdata%\Microsoft\teams. Then delete the following files. You can move the files to another place to avoid the data loss:
· In Application Cache -> Cache folder, delete all files in it.
· In Blob_storage folder, delete all files.
· In Cache folder, delete all files.
· In databases folder, delete all files.
· In GPUCache folder, delete all files.
· In IndexedDB folder, delete the .db file.
· In Local Storage folder, delete all files.
· In tmp folder, delete all files.
· Delete the file “settings".
Mac:
------------------------
1. Quit Microsoft Teams.
2. Delete files in following folders.
“~/Library/Application Support/Microsoft/Teams/Application Cache/Cache”
“~/Library/Application Support/Microsoft/Teams/blob_storage”
“~/Library/Application Support/Microsoft/Teams/Cache”
“~/Library/Application Support/Microsoft/Teams/databases”
“~/Library/Application Support/Microsoft/Teams/GPUCache”
“~/Library/Application Support/Microsoft/Teams/IndexedDB”
“~/Library/Application Support/Microsoft/Teams/Local Storage”
“~/Library/Application Support/Microsoft/Teams/tmp”
3. Restart Microsoft Teams.
Kind Regards,
Anna
