Email Attachment Limit

Email size limits.

These are the email size restrictions:
  • 25 MB external emails to an internal email
  • 25 MB internal email  to external email
  • 50 MB, in theory, from internal email to another internal email
    • Don't expect 50 MB all the time. If an email between 25 MB and 50 MB isn't sending, use OneDrive to share attachment/email.

Note: Please keep in mind external email hosts may have their own email size limits lower than ours. 

Summary: Expect a 25 MB e-mail size limit except for a email to another email, where in theory, the limit would be 50 MB.
