This means your Jira has not got the certificates needed to connect to your mail server.

You'll need to talk to your mail server admins about getting a valid certificate to allow access.

Hello Nic,
We are using outlook.com SMTP for mail functioning.

SMTP Server : imap-mail.outlook.com

We need to import its certificate at Jira keystore.

Yes, that's what you need to do, that will allow Jira to offer a certificate to the server asking for one.
