How to read Teams.msrtc files (uLog format)

Super Contributor


Playing with Teams folder and found from %appdata%\Microsoft\Teams\media-stack files which might share a bit more what Teams does. When opening files they seems to be "ULog" formats(?).


Is here anyone else playing with these files, and have ideas if there could be something useful in them?

You can't read them , only SEEs in Microsoft Support have the proper tools to  decrypt and read them.


Yes, I have noticed that. But I wish Microsoft see how valuable that would be for them if we could do the troubleshooting and find out simple FW rules issues, for example.


Do you know that those are really encrypted? As I thought that is only a binary ULOG2 format.
