Microsoft made it simple for the users to switch from one product to another. The perfect example is the Microsoft-Outlook integration. With simple procedure by doing one-two mouse click, you can quickly access to Microsoft Teams directly from the Outlook email client. All that you need to do is to add Microsoft Team add-ion for Outlook. Once you do that, you will find a new icon appears on the ribbon at the top of the Outlook page associated with it.
Lately, people have reported about Teams add-in not showing in Outlook error. Even when the people install the add-on to the Outlook, they can’t see this option. This frustrates them while scheduling group discussion or meeting as they now have to go with the old and tedious method – to start Microsoft Teams separately and then schedule the meetings and work.
What causes the issue under discussion?
People reported about the problem when they see Teams add-in not showing in Outlook Toolbar. While in some cases, it is just that the toolbar is not placed in the visible location, Outlook may disable the add-on and its toolbar because of conflicts caused by third party add-on or because of add-in performed such actions that caused the Outlook to stop responding.
Some of the possible causes what could lead to this issue include:
- Outdated Office: The problem could occur because you are using older, incompatible version of Office. You should require having Office ProPlus or Microsoft 365. You can check it manually from the applications like Word and then by selecting File> Account and then within the Product Information.
- OAuth Exchange Authentication: Microsoft Exchange stores the add-in manifests within the organization’s tenant. Add-ons deployed by admin and the one received by users must have a version of Exchange server that supports OAuth authentication.
- Nested Groups: Users might remove the add-ins from a group that the add-in is assigned to. Currently, centralized deployment does not support nested group assignments. It supports users in top-level groups or groups without parent group and not any nested groups or group with parent groups.
- Authentication Requirements: To use the Add-on on Outlook, you require signing into Terms and using Modern Authentication. Microsoft prefers using multi-factor authentication.
Possible fixes for Teams add-in not showing in Outlook
After understanding the nature of the issue and the possible reasons what could cause, we are now at the position to discuss its fixes. But, before that we have shared below what are pre-requisites to follow the troubleshoot steps:

- Install MS Team Apps with Admin Privileges: one requirement for successfully using the add-on is to run it as administrator. This is required so because COM add-ins to Outlook writes to Windows registry and only administrators can modify the registry.
- Run Outlook in Normal Mode: When starting Outlook, instead of running it as elevated permissions, run simply as it may interfere with identifying registered COM add-ins.
