Email attachment and recipient limits

This document outlines the size limits for UW-Green Bay emails and the maximum number of recipients.

The maximum number of recipients is 249.

These are the email size restrictions:
  • 25 MB external email to an internal email. 
  • 25 MB internal email to an 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.
