Activate the compatibility mode for Microsoft Teams
One of the most common problems during the installation of Microsoft Teams is incompatibility with third-party applications. This happens because Team Services uses different APIs to communicate with Office 365 products like Outlook, Word, Excel, PowerPoint, etc. When you install Microsoft Teams, it automatically checks whether your current version of Office is compatible with the latest release of Teams. If it detects compatibility issues, it tries to fix them by running some commands. Unfortunately, sometimes those fixes don’t work correctly and cause additional problems.
In order to avoid such issues, try running Teams in “Compatibility mode.” When you use this mode, Teams will not attempt to update Office 365 components, but will instead use the old versions. The error messages will look slightly different, but they’ll still be the same. For example, you might see something like, “A component is missing from the application ‘Microsoft Office 2016’.”
Make sure you have at least 1607 installed on your computer if you are using Office 365 ProPlus. If you are getting similar errors, ensure there are no errors before moving on.

When prompted, click Yes.

The computer should be restarted.
