1 min read

Answer

The default attachment size limit in Outlook is 20 MB for most accounts.

Workarounds:

  1. Compress Files: Use a zip tool to reduce file size.
  2. Use OneDrive: Upload large files to OneDrive and share a link.
  3. Split Attachments: Send multiple emails with smaller attachments.
