If you haven’t used this method to sign in, you will still be able to use Microsoft Teams but will be unable to schedule Teams online meetings through the Outlook add-in.

Save these settings and then you should be able to use the Teams add-in for Outlook to schedule private meetings.

Some considerations

While the Microsoft Teams add-in for Outlook is a really useful feature for many users, it is important to bear in mind that there are some limitations to its usage.

Firstly, Microsoft Teams is a young program and the Outlook add-in is even more recent. As a result, it is still building functionality and is not perfect just yet.

Users should also be aware that the Teams add-in for Outlook allows users to schedule private meetings. It is not able to schedule meetings in a channel. Channel meetings have to be scheduled within the Teams app itself.

You also cannot use the add-in to schedule live events. These also have to be scheduled within the Teams app at the moment.

Microsoft also cautions that the Outlook add-in will not work if an Authentication Proxy is in the network path of the user’s PC and Teams Services.


The popularity of Microsoft Teams is growing rapidly and one of its big attractions is the way it can be integrated into other popular Microsoft software programs.
