In testing I've done with Outlook I've never seen it "auto-subscribe" to IMAP folders. Not saying it didn't happen for you, or that it can't be configured; I've just not found it to be the case.
As far as putting it into the Wiki, subscribing to folders is a fundamental step of using just about any e-mail client with any IMAP server; nothing really Zimbra-specific about it. At least that's my opinion. |
