Is there any simple way to keep the local On My Mac mail folders synced between two or more Macs? I have a work laptop and a home machine and I'd like to keep the local saved messages the same between both. I assume that I could use iCloud Drive to house the folders, but not sure if I move them that mail will find them (no way of doing that in preferences). The email accounts are Gmail and an MS Exchange account. I don't use iCloud to sync Mail because I found it interfered with my Exchange functions. Thanks!
