How big of an attachment can I email?


It depends on how big the sending email server and the receiving email server are configured for.  If the total email size with attachment exceeds either server's limit, your receiver will not receive it.  Listed below are the size limits for GTRI Exchange and MyGaTech.

Office 365:  35 MB

Email server administrators can set the size limit to what they want, but here are some common message size limits.

Exchange default:  10 MB
Gmail:  25 MB
Hotmail:  25 MB
Yahoo:  25 MB
Zimbra default:  10 MB
