Hi @136 Kishore Thammisetti ,

Welcome to the community !!

As @John Funk  mentioned, user needs the right permissions in the project. Minimum required is Browse project permission. If a user has the required permissions, then you can add that users to watchers list or directly share the issue with. You can also mention/tag the user in the comments.

Hi Kishore - Welcome to the Atlassian Community!

You share issues by granting the appropriate permissions in the Permission Scheme for the project.
