Frequently asked questions
You can share files in a one-on-one chat, a group chat, or a team channel. Select the paperclip icon below the box where you type a message to upload a copy of your original file. You can also upload a file by going to the Files tab of a chat and selecting Share.
Files you share in a channel are stored in your team's SharePoint folder, which is found in the Files tab at the top of each channel.
Files you share in a private or group chat are stored in your OneDrive for Business folder, which is found in the Files tab at the top of a chat. These files are only shared with the people in that conversation.
Learn more about how SharePoint Online and OneDrive for Business interact with Microsoft Teams.
Because Teams file sharing runs on a SharePoint Online backend, SharePoint limitations apply to the Files section within a Team. Learn more about applicable storage limits for SharePoint Online.
Only team members can see team files. You can share a file with people outside your team, if they are also using Teams, by sending it to them in a chat.
If you want to share a file with someone outside your organization, open the file in Office Online or an Office app and share it from there.
Files uploaded and shared to a team are accessible to every member of the Team. In Office for the web, Office for Android or iOS1, or the latest applications from Microsoft 365, you and your team members can coedit Word, PowerPoint, or Excel documents, or comment on Visio files. You don’t need to check files out or worry about colleagues having the document open. Just open the file you want to edit, and if other team members are also editing it, your changes will be seamlessly merged as you work.
Learn more about using and sharing documents in Teams in the Microsoft Support website.
