What is the maximum email size and attachment I can sent out at a time? Print

The maximum email size, which includes the message and any attachments, is 50 MB.

 

You may attach as many files as you like as long as it does not exceed the 50MB limit. This limit applies to all forms of connections, whether the user is using the webmail interface, or an email client such as Outlook or Thunderbird via POP/IMAP.
