Reasons Why Microsoft Teams Keep Reinstalling

The reason Microsoft Teams continues reinstalling is simple: it was never entirely removed in the first place.  This can occur with certain Office Software App installations, particularly when it is packaged and deployed as part of an organization-wide Office subscription.

If this is the case, Microsoft Teams will come with two pieces of software installed. The first, Microsoft Teams, is what most people will search for and remove.

The second, Office Software App Machine-Wide installer, is software that is used in Microsoft Office enterprise deployments to automatically install Office Software App across multiple PCs. If you have the Office Software App Machine-Wide Installer installed, Microsoft Teams may continue to install even after you have uninstalled it.

If you wish to prevent Office Software App from reinstalling, you must delete this when you uninstall it.
