The storage location of Microsoft Teams files depends on the usage scenario: 1. Private chat files are stored in OneDrive, located in the "Microsoft Teams Chat Files" folder, and counted into personal storage quotas; 2. Channel files are stored in the SharePoint site document library of the corresponding Team, supporting collaborative editing by multiple people; 3. Storage restrictions are determined by the organization's Microsoft 365 license type, OneDrive is allocated by users, and SharePoint is an organization's shared pool, both of which need to pay attention to quota management.

When you upload files in Microsoft Teams, they don't just live inside the app itself — they're actually stored in connected services like OneDrive and SharePoint. This setup helps keep things organized and makes file management easier across Microsoft 365 apps.

Files in Chats Are Stored in OneDrive

If you send a file directly to someone in a private chat, that file gets saved in your OneDrive account. Specifically, it goes into a folder called “Microsoft Teams Chat Files.” This folder is shared with anyone you send the file to, so they can access it too.

• You can find these files by going to your OneDrive website or desktop app.
• These files count towards your OneDrive storage limit.
• If you delete the file from the chat, it also gets removed from OneDrive (and vice versa).

This is useful to know if you're trying to clean up space or recover something later.

Files Shared in Channels Go to SharePoint

When you upload a file in a Team channel , it's actually stored in the associated SharePoint site for that Team. Each Team has its own SharePoint site collection, and each channel has a document library within that site.

So, for example:

• If you upload a PowerPoint to a "Marketing" channel, it's stored in the Marketing channel's document library in SharePoint.
• Anyone with access to that channel can view and edit the file through either Teams or SharePoint.

You can go directly to the SharePoint site by clicking the “Files” tab in any channel — this shows the full document library with extra tools like sorting, filtering, and version history.

File Storage Limits Depend on Your License

How much you can store depends on the type of Microsoft 365 license your organization has:

• OneDrive storage: Each user typically gets a certain amount — often 1 TB or more for business licenses.
• SharePoint storage: The entire organization shares a pool of storage, which can scale up if needed.

If you hit your limit, you might need to archive old files or ask your admin for more space.

Basically, where your files end up in Teams depends on how you use them: one-on-one chats use OneDrive, team channels use SharePoint, and both tie back into your organization's overall Microsoft 365 storage plan.
