Microsoft Teams News: Wiki Page Retiring in January 2024 & There Are Things You Must Do

Thanks for starting this informative blog Teresa_Cyrus! 

I may be stating the obvious but wanted to maybe give a couple of discovery pointers to anyone that may need them. I am an admin and did not want to rely on users to complete the discovery work. I had a total of 112 sites with teams and was able to get through these discovery steps over the course of 3 days while still completing other duties.

Start with producing a SharePoint list of Sites with Teams in the SharePoint admin center.

Download it and use it to document what you find/do.

For each Team:

1. In the Teams admin center add yourself to the team and to any private channels
2. Check the tabs for Wiki content. Don't just check the tab labeled Wiki as the tab may have been renamed.
3. If the tab is a Wiki and it's empty, remove it.
4. Check every Channel's tabs. Make sure you expand any hidden channels too.
   1. Optional steps: Open the site in SharePoint. Private channels create their own Sites so make sure you open them too.
   2. Navigate to and open Site Contents.
   3. Open library 'Teams Wiki Data'.
   4. Check under each folder for content.
   5. Delete empty folders or if there is only 1 or 2 'untitled' .mht files.
   6. If nothing is found of value, delete the Library 'Teams Wiki Data'.
   7. It's important to note that I did find folders in the Library that didn't have a folder by the same name as channels for the team with content. I suspect these were from channels that were removed. You may want to keep this content.
5. In your SharePoint spreadsheet, make a note for what you did and if there are any Wiki's present to migrate.
6. Remove yourself from the Team.

Does anyone know how to exclude the Wiki App from being used in Teams? I would love to not allow anyone to add a Wiki now that I completed my research to find all the Wikis!

I did a little test too for new sites getting created.

When you create a New Teams SharePoint site and add a Team or create a new Team in Teams, the Wiki tab was not included and the library 'Teams Wiki Data' was not created. That was a relief! I hope that experience is the same for everyone.

Hope this helps folks to prepare for the next steps!
