TL;DR summary
- Microsoft Teams Wiki data is stored in SharePoint in a document library at Site contents → Teams Wiki Data
- Each Teams channel with a Wiki has its own subdirectory in the Teams Wiki Data document library.
- Each Teams Wiki page within a channel subdirectory is stored as a .mht file in SharePoint.
- Backing up the contents of the entire Teams Wiki Data document library is the best way to back up Microsoft Teams Wiki pages.
Where are Microsoft Teams Wikis stored?
Teams Wikis are stored as .mht files in SharePoint at Site contents → Teams Wiki Data.
To get a better idea of how this all works, let us take a look at what happens in SharePoint when you create a Teams Wiki page. If you are an administrator within your organization, you can follow along with us.
In Teams, we can see our organization has five channels.
Each channel has at least one Wiki page, and our “Bakery” Wiki has two pages.
Now, let us take a look at the SharePoint site for the same organization. First, we need to log in to our SharePoint account. Then, from the Home page, click Site contents.
Next, we click Teams Wiki Data.
Now we can see there is a subdirectory for each of our channels with a Wiki page.
Clicking into the General directory, we see one .mht file with a name that matches the title of the General Wiki.
If we move back up to the Teams Wiki Data document library and click into our Bakery directory, we can see it has two .mht files. This makes sense because there are two pages in the Bakery Wiki.
Additionally, if we make an edit to a Wiki page, we can see that SharePoint updates almost instantly. That is great news for those of you with RPOs measured in seconds!
About .mht files
Now that you know where Microsoft Teams Wikis are stored, what exactly are those .mht files?
MHT files — which are also known as MHTML files — are a type of web archive. They include all the HTML and resources on a page in a single file. Because they are plaintext files, they can be opened using standard text editors like Notepad. Additionally, some browsers can open MHT files directly, while others require an extension.
When you open Teams Wiki .mht files (we used Internet Explorer in the screenshot example below) you will notice a message indicating changes made in the file will be overwritten.
That message makes it clear that you cannot edit or create Teams Wiki pages simply by uploading new .mht files in SharePoint.
