Hello. As I explained in another question, I use filtering rules to move the incoming emails to their definitive place in a tree of folders, and I look at them through a set of permanent Saved searches using specific criteria this is very handy. I created the set of saved searches at once (all in the folder _Vues = Views in French), but they don't all work the same, as visible in the attached image: - all properly turn to bold, like other folders, when having messages in unread state, - but some of them don't turn to blue, while others do, when having new messages, - the real folders don't appear to have any problem, they do turn blue when the new messages are moved to them. This looks like a little cosmetic problem, but it is very annoying as it forces to look at all the searches instead of only the relevant ones. All the accounts use the option to share a single input and output box in the Local Folders. There is no structural difference between the saved searches (names etc.). Some emails meet the criteria so should appear in multiple saved searches. I suspect this is the key of the scenario, where for a given incoming email, only the last saved search found matching it would turn to blue, then the global result would depend on the set of incoming emails... Understanding this would require to know the exact algorithm used. Can someone explain what happens ? Thanks, Best regards.
