I can't use that method! What to do next...

You may not be able to use some of the "native" methods to record meetings (you are not a Teams admin, you are never the host etc etc).  

We have put together a number of other alternatives for you, that might help:

Windows 10:

Use the Myna recorder:  We have a great app that records audio and video, and starts and stops when your meeting begins and ends. Download from here. Instructions on the  install are here, and the setup instructions are here

Use the Windows native recorder: Quick to run, but it uses up a lot of space.  Instructions are here

Mac:

Use the screen capture tool: Again, it uses up a lot of disk space, but it is effective.  Instructions are here

Linux:

At this point, all suggestions gratefully received!
