Smart Mailbox not refreshed automatically

You might want to also read what Apple says about using Smart mailboxes at Mail for Mac: Use Smart Mailboxes to organize messages

It talks about creating Smart Mailboxes as well as Smart Mailbox Folders which are special folders that contain Smart Mailboxes.

Good luck...

Perhaps you could take a screen shot of the smart mailbox you created showing the rules? To take a screen shot of an area of the screen, you can use the Command+shift+4 shortcut, and when the cursor changes to a bulls-eye with screen-coordinates you can sweep out an area (click and hold at top left corner and then drag to bottom right of area) of the screen and when you release the screen shot will be written to your default location (by default this is your Desktop but it's possible to change this, so is system dependent).

Good luck...

Well, that certainly looks like it ought to do the job.

But a funny thing happened when I tried to create one just like it. When I said 2 weeks, it only found messages dating back thru Mar 27 (which is a little less than 2 weeks), but when I chose 14 days, I got what I thought I should (back thru Mar 23), so maybe "week" is defined in an odd way (like everything this week and last week???). Try 14 days and see if you have better results.

Good luck...

See if something like this works. List all the mailboxes you want checked.

Think that Eric Root has an excellent suggestion. I hope that you have success with that.

Good luck...
