The Wiki Tab or App in Microsoft Teams is a webpage using the smart-text editor to communicate information to your public or private channel. It is like Wikipedia, where the content originators provide information and allow others to add or edit content. So, in Microsoft Teams, the Wiki App gives users another collaborative workspace where you can add hyper-rich text, images, and tables onto a webpage.
A Wiki webpage can include multiple Pages and Sections. A Page is the top-level subject matter that may contain various sub-topics grouped into Sections. In addition, you can toggle the Table of contents menu by clicking on the three horizontal lines. The TOC menu also controls the behaviors for a Wiki Page, like adding a new page or reordering pages and sections. The Conversation pane appears when you start or review existing discussions.

When to use a Wiki in Microsoft Teams
Although there is no limit to how one can use the Wiki webpage, it is a misunderstood app resulting in an underutilized application in Microsoft Teams.
Here are several suggestions. However, I recommend that the content only be relevant to a specific team channel.
- Onboarding/Welcoming. Create a webpage for all new team members. You can provide a welcoming message, team channel purpose, where to find content, address frequent questions for newbies, and post links.
- Frequently Asked Questions (FAQ). Create a FAQ page to reduce questions about policies, processes, who to contact, or meeting schedule. This webpage can increase productivity for all members since you are not wasting time searching or answering the same questions. Besides, now you can send the link to a Wiki Page or Section.
- How To’s / Knowledge Transfer. If you already have a SharePoint site containing information, do not duplicate the content on the Wiki Page. Instead, post links to the how-to guides, processes, policies, or manuals. Now, you have created a quick links page.
In my opinion, I would use a Wiki Page in Microsoft Teams as a Quick reference to the detailed information, especially if you are using a SharePoint site. Take advantage of the Wiki App if you do not have a SharePoint site. Share how you plan to use the Wiki App in the comments below.
What are Wiki Page Limitations?
Every app has limitations, and the Wiki app is no exception.
- Can not copy a Wiki page to another Page or Channel.
- No Wiki Templates. For consistency, you would like to create a reusable template for other channels within your team or even for a Page within the Wiki Page. No can do!
- Can not change font attributes in the Page and Section headers. Although you can change the font color, size, and emphasis in the section’s content area, it is blocked for the titles.
- Recover a Deleted Wiki Tab. Microsoft warns the user that removing the Wiki Tab is permanent. And it is gone forever. So, make sure you want the Wiki Tab and all its content permanently gone.
- No Recycle Bin for deleted Wiki Page and Section. Usually, when content is deleted, the items are moved to a recycle bin. Well, that is not the case for Wiki pages and sections. Oh yea, Microsoft provides a warning saying it is permanently deleted, but they are saved in SharePoint. In a separate blog post, I will show you a workaround on how to retrieve deleted pages and sections from SharePoint.
Here is my encouragement message to you. You can influence change by adding or voting on Wiki Page improvements on the Microsoft feedback portal.
How to Add a New Wiki Tab in Microsoft Teams?
You must add the Wiki App to generate a tab in the top menu.
Starting in mid-August 2022, Microsoft announced that the Wiki App is not a default tab in the top menu when a new team channel is created. For existing channels, the Wiki Tab will remain in the menu regardless of if it is blank or used.
- Click on the plus sign located at the top menu.
- From the Add a Tab menu, locate and select Wiki.
- Name your Wiki Tab and press Save.
Tip: Give your tab a short name so it will not take up a space in the top navigation. Remember, you can give your Wiki Page a more descriptive title later.
- A blank Wiki page will appear.
Editing a Wiki Page
The Wiki Page is a rich-text smart editor. Most of Microsoft’s standard fonts and paragraph attributes are available. You can also insert quotes, hyperlinks, horizontal lines, images, and tables.
Headers
Place your cursor in the Page and Section headers and begin typing. As I had mentioned earlier, you can not change the font size or color.
Content area
Place your cursor beneath the Section header to launch the editor. A purple vertical line will appear to the left of the section where you are typing.
Content area
Place your cursor beneath the Section header to launch the editor. A purple vertical line will appear to the left of the section where you are typing.

Reordering Wiki Pages and Sections

Wiki Tab: When you remove a Wiki Tab, it is bye-bye forever. So, make sure that it is what you want to do.
- Click on the Wiki Tab drop-down menu and select Remove.
- If you are sure, click Remove in the warning dialog box.
Wiki Pages and Sections: As a reminder, only the SharePoint owner can recover deleted Wiki Pages and Sections, getting them back is not a fun task. The steps to recover a Wiki Page and Section from SharePoint are covered in a separate blog post. Here are the steps to delete these items.
- Show the Table of Contents Menu by toggling on the three horizontal lines.
- Click on More Options, the three dots, next to the Wiki Page or Section you want to move. Click on the Delete
