SMTP Mail Message: The operation has timed out

The SMTP Send Mail Message Activity did work before and now I see the timeout error. I tired “delay”, Updated Packages and also checked if the SMTP connects works. Still see the error.

Firstly are you able to perform any other SMTP activities?

if yes, Try increasing the timeout.

Are you attaching anything huge?
