Send a file that is too big for email
Share a link from OneDrive instead of attaching the file.
Most email systems reject messages over about 20 MB. A link works better, and it keeps you in control of who can open the file.
- Save the file in OneDrive, or open OneDrive in your browser and upload it.
- Right-click the file and choose Share.
- Pick who can open it. Choose Specific people and enter their email addresses, rather than Anyone.
- Choose Can view unless they need to edit, then select Send.
Good to know
For files with private information, always pick specific people. See Share a file safely.
