An error occurred while attempting to establish an SSL or TLS connection during using SMTP or IMAP

Send SMTP Mail Message: An error occurred while attempting to establish an SSL or TLS connection.

One possibility is that you are trying to connect to a port which does not support SSL/TLS.

The other possibility is that the SSL certificate presented by the server is not trusted by the system for one or more of the following reasons:

  1. The server is using a self-signed certificate which cannot be verified.
  2. The local system is missing a Root or Intermediate certificate needed to verify the server’s certificate.
  3. The certificate presented by the server is expired or invalid.

See MailKit/FAQ.md at master · jstedfast/MailKit · GitHub for possible solutions.

which version of UiPath you are using ?
Try wiht port 587
Set startTLS option in “options” under properties.

Also, check if you are able to succesfully test telnet to that host and port

telnet hostname port

Thanks,
Arun

Not sure why, for me it is asking host nand port. Not as HostDisplayName and PortDisplayName.
Can you try updating the package once.

Is there any problem on UiPath installation?
Do I need to download or install something else?

8

just the package needs an update , not complete installation,

Did you try if telnet is working.
Execute below command in command prompt

telnet <<Host_Name>> <>

This is mainly due to installation to of the any Antivirus software in your system. Neither you can uninstall the antivirus or change the setting of certificates in your antivirus.

Firstly Open gmail account of your credentials and go to security settings and “Turn On” in Less secure app access
