Combining mail boxes

How exactly do you combine emails from different mail boxes? Thanks.

  1. You can combine whole mailboxes by selecting them and using the Merge Mailboxes command.
  2. You can combine individual messages for display purposes by assigning them the same tag and then using the tag source as a kind of virtual mailbox.
  3. You can create an actual mailbox file containing individual messages from different mailboxes by selecting the messages and choosing File > Export…. The mbox file could then be imported into the library. This would not preserve tags and notes, however, as they are not supported by the mbox format.

Thanks
Thanks, Michael. The Merge Mailboxes command did the trick.
