Does anyone know if it's possible to move a "Mailbox" in Apple Mail to an external drive? I have a relatively small SSD drive, and I'd like to create an Archive mailbox on an external drive.
I don't want to move the entire
~/Library/Mail folder - just the Archive mbox.
If I create a MailBox called
MyArchive, I can see the .mbox structure in
Is what I'm trying to achieve do-able? I know there's "proper" mail archiving utilities, but if I could just store the native emails on an external disk, it'd be good enough for me ...
EDIT: As discussed below, I've tried moving this folder to the external drive and creating a symbolic link to it, but with this in place Mail.app doesn't see the mail content in the folder - I can see the list of mail items in the mailbox, but opening any mail in the folder results in a "blank item". I also see the error
kernel: Sandbox: Mail(99229) deny file-read-data /Volumes/External HD/MyArchive.mbox/ (followed by the path to the .emlx)
Is there any way to "override" Mail.app's sandbox settings to allow it to read mail from the external path?
