Why am I not able to mention an user in a conversation?

Why am I receiving an error message when mentioning a user?

If you're receiving below error message when mentioning a user, it may be because the system is checking the user's access to a specific feature or resource before allowing the mention to go through.

Winmore implemented an API to check access permissions for users before mentioning them in a conversation, particularly regarding access to ES (Enterprise System) resources. If the user being mentioned does not have the necessary access to the ES resources, an error message may appear to notify you of this restriction.

What to do if you receive an error message when mentioning a user?

If you encounter an error message when mentioning a user, ensure that the user you're mentioning has the appropriate access permissions to the resources being referenced in the conversation.
