Hello,

I’ve had this issue twice in the last year, the first time I couldn’t remember how it got resolved.
The same code worked on a another physical or virtual machine but not my machine.

I noticed that if I tried sending mail using the Exchange UiPath activity the email would be sent but not with the SMTP activity.

In the end I rebooted my machine connected back into the office over the vpn and it started working. I think it was something to do with my VPN connection being on for days (possibly the company enforcing something or the other or a timeout has occurred).
