I noticed you can select “Status = Starred” in this search message function, but you can only apply it to one account, so you would have to repeat it for each account : defeating the purpose of having starred in one place.
The only way I can find to view starred messages is to go to each account folder individually & locate the starred folder.
Its baffling that TB provides a STAR on every email & then no way to see a list of starred messages. & doubly baffling that its a 17 year old issue.
