I was doing a blog yesterday on system-preferred MFA. And during the writing of this blog I needed to clear the cache since the new Teams 2.1 desktop client wouldn't allow me to completely sign out. It was still trying to sign in to an old tenant which was previously linked and which I had removed after it had entered a grace period prior to it's expiry. At this point signing in wasn't possible. It wasn't possible to get the desktop client back to the sign in page either. So this is the kind of issue which - historically, clearing the cache is ideally suited. But what was weird about this scernaio was that when I cleared it from the usual location, closed down explorer and restarting the client clearing it didn't seem to resolve it. So I am now trying to a few different things, clock-watching and running out of time to do this blog. And what suddenly clicked in my head was to check the cache again. So I went back in explorer and the cache didn't re-populate when the Teams 2.1 client was reopened. Therefore, the cache for Teams 2.1 desktop client is actually in a different location than the classic desktop client. So I rooted around a bit. I found it. I actually found a way to it through the client itself, but I am sure it's going to be easier to simply use Run as most do today. Now, clearing the cache is part of the repotoire of pretty much anyone who supports Teams. Better we all know where it is. But will it go back to the usual place when we transition over fully? Who knows!
