Hi @RPollina, I just came across this issue, too.
Users experience this only within the Teams Client on Windows, it is not occurring if the users join a Teams online meeting by using the browser.
Did you try to join a meeting via browser?
I opened the task manager during an online meeting however the utilization of CPU/network/RAM/... was very low, so I guess it's not a client hardware topic. Altough I cannot exclude this for 100 % right now. Maybe wrong or "outdated" system device drivers could cause this issue... e.g. wrong NIC drivers, wrong audio ... drivers...
I've checked network connectivity towards Microsoft SFBO/Teams by using the SFBO network assessment tool https://www.microsoft.com/en-us/download/details.aspx?id=53885
Results were ok.
I also checked the firewall/proxy (SSL / packet interception ... were off).
As a next step I'll test to temporarily turn off the thirdparty antivirus scanner on a Windows PC to exclude the AV scanner as issue source.

Hi @RPollina , I'm not yet sure. I'm still investigating this issue.
I'll also try to set up a new clean Windows machine, not domain joined, update it with the latest updates for Windows as well as Office. Than I'll check if the issue remains if the user joins a meeting via this (test) Windows client.
As far as I figure out something new I'll also answer to this thread but I'm not sure when this will be.

Hi @RPollina, still on it, we're investigating towards firewall because the issue does not occure if I test this on a "unmanged" internet connection, i.e. if the user/s are located remote at home without VPN/DA... And the network monitoring/reporting did not show such bad network metrics towards O365...

Hi @HaydenMoulds, sorry, I don't have any further details on what the FW admins did to fix it. I only provided the Office 365 URLs and IPs list which need to be accessible by Microsoft Teams clients. I'd guess that they had not set up these URLs/IPs correctly or had some packet inspection or interception configured. Best Regards Erik

There seems to be an ongoing issue with Teams cutting off during meetings. This can be pretty embarrassing. Ever since the COVID-19 lockdown, I have had to tutor remotely using Teams. My camera also constantly dies and will not switch back on again. The audio drops and network error messages keep popping up. Microsoft, as usual specialise in avoiding customers. They have launched this Skype Business Network Assessment Tool, but as typical of Microsoft, it's just another useless fob off to keep customers off their back. I don't see a great future for Microsoft Teams since it is beset with bugs and communication problems, so I am thinking of moving to Zoom instead.
