If you are running a previous version of macOS, such as Big Sur, Catalina or Mojave, you should not need to do anything.

MsgFiler Engine 1.5.2 and MsgFiler Classic 2.5.2 plugins have been updated for support with M1-powered Macs running macOS Big Sur.

The MsgFiler Engine and MsgFiler Classic Mail Plugins currently do not work on M1-powered Macs running Big Sur.

I’m awaiting my M1 Mac Mini in mid-December and hope to have new versions of the plugins by the end of the month. Stay tuned!
