Search function doesn't work in mailbox

Ladies and gentlemen - issue:

When viewing the mailbox:

User types a keyword, hits enter. I can see the keyword before I type it but when I hit enter, we don’t ‘jump’ to it.

When viewing another database:

User types a keyword, hits enter. I can see the keyword before I type it and when I hit enter, we ‘jump’ to it, confirming the search function works.

Any help is appreciate - thanks in advance.

Subject: read the box…

it says: "Starts with…"If you start typing it searches the text that begins with the typed text in the first sorted column.

In your mailfile this is usually the Date-Column. If you sort the view by ‘Who’ you can start typing the name, if you sort it by subject then it looks for the subject starting with the typed text.
