Aside from my inbox, I have other folders I use to categorize my mail. For example, one folder "ProjectA", which has subfolders "Subfolder_IssueA" and "Subfolder_IssueB".
I would like to click on the folder "ProjectA" and see all mails contained in the various subfolders. Is this possible?
Maybe relevant information: I have to move the mails manually to the subfolders, I don't see any way to create a rule for a search folder that can automatically categorize this.
