How can I run the new Microsoft Teams on macOS Monterey 12.7.6 if it's now marked as incompatible?

With all due respect, stopping support and stopping something from functioning are two completely different things.

When Microsoft stop supporting Windows 10 in Octopber it will still work on people's computers. It will stop recieving security updates and it will be up to the user what they do. Support ends, it still functions, the user makes the choice.

What you're saying makes perfect sense for an application like Word that functions almost entirely just on your device. Or for an application like Outlook that uses a standard network protocol. But Teams uses a dedicated Microsoft system. It's not just the app that needs to be supported, it's that back-end system. And supporting older versions of Teams on that system will almost certainly stop being practical or profitable at some point.

The Age of this computer will Govern what newer version of macOS it will Qualify to install.

Thing is, we don't need or want to run the latest version.

The last compatible version of Teams for Monterey no longer boots even though we have not changed either the OS or the version of Teams. It worked yesterday, it does not work today.

Microsoft have deliberately blocked it from working. If I am on Catalina, I can still run Teams Classic with one warning when I boot it. It's something MS have put server-side to block it. We have 8 Macs here that are unable to go any higher but this is absolute nonsense from MS. I have trawled through the code but it is at their end so we are stuck.

They don't need to support it but they also don't need to purposely block it either. If anyone has any ways around it I'd love to hear from you.

I'm still able to use Teams Classic on Monterey. In fact I only updated that system to Monterey last year long after Apple dropped support for Monterey. I never installed or used the new Teams app on that system.

I also a system running Big Sur which does have both the Classic & new Teams on it, but Classic Teams is still working there as well and Big Sur is a year older than Monterey.

I haven't tried any video calls with either system, but all the Teams channels & chats are all there.

Well, thing is, we don't know what is going to happen in July. We shouldn't be able to run Classic in Monterey but we can. A lot of the frustration from users is MS not being clear on what is or is not actually going to happen.

I'm using a very very old Outlook on one of my Macs and it is working fine. It has been unsupported for a very long time. I suppose it comes down to can Microsoft scupper the usage from their end? With Outlook it still has to connect via imap or pop, those protocals are set, so we may not get all the new features but it still works.

First thing Teams does, is it contacts to the MS Teams servers and that is where they are crippling the application usage. Classic still works as it physically cannot switch to the new version because it realises the newest version won't run on Monterey and it cannot push the 'locked out' splash screen to Classic. It'll be interesting to see what happens in July but MS should just stop blocking the last compatible version for Monterey and let it run with a 'You may not be getting the newest features' and let us decide. Afterall, we are paying for it.

Nope. The app has been programmed to "die" once your OS passes the age that they will support. We're not talking about updates or support. It literally will not allow you to launch any more.

Hi Octopi,

I tried everything you suggested but I still get a pop-up that states Classic is not supported and to use the web.
