Solution 1Recommended

Use the Channel Header App Icon to Pin a Tab

Since Microsoft has relocated the Add Tab entry point for early release users, you must use the new app icon to add or pin channel tabs.

For users enrolled in Targeted Release or Public Preview, Microsoft has moved the 'Add a Tab' functionality to streamline the channel interface. The familiar plus button has been replaced by a new entry point located in the top-right corner of the screen.

1
Navigate to the channel header

Open Microsoft Teams and navigate to the specific channel where you want to insert a new tab.

2
Select the App icon

Instead of looking for the old plus (+) button, look to the top-right corner of the channel header and click the 'Apps' icon.

3
Add your required application

Search the app directory for the specific integration you need (such as Planner, Excel, or Channel Tab Group) and select it.

4
Pin the tab to the channel

Once the application is added to the channel, look for and select the 'Pin a Tab' option to secure it to your top navigation bar.

Interface Variations: The exact location and availability of the 'Pin a Tab' option may vary depending on your current Teams release build and your organization's specific IT settings.

Frequently Asked Questions

Why did Microsoft remove the plus button in Teams?

Microsoft frequently updates the Teams interface to streamline the user experience. For users in the Targeted Release or Public Preview, the functionality of the plus button has been consolidated into the 'Apps' icon in the top-right corner to better organize channel extensions and integrations.

How do I know if I'm on a Targeted Release or Public Preview in Teams?

You can check your update channel by clicking the three dots (Settings and more) next to your profile picture in Teams, navigating to the 'About' section, and seeing if 'Public preview' or 'Developer preview' is checked.

Can I revert to the old Add a Tab interface with the plus button?

If your organization's IT admin has enrolled your account in Targeted Release, you generally cannot revert the interface individually. However, if you opted into Public Preview by choice, you can switch back to the standard release via the 'About' menu in Teams settings.
