If one of our staff adds a comment to a ticket, and uses @thomas or other user to send a email message to another staff member. 

Once the other staff gets the message and clicks on View they sometime receive the following error:

Insufficient Privileges to perform this operation. Contact your Administrator.

Is this an issue you have seen before? Can you please advise how we might correct this issue.

Thanks,

Thomas Pursifull
