palm365-mac bidirectionally syncs a Palm OS PDA's calendar, tasks, and contacts with a Microsoft 365 account. It runs automatically as a jpilot plugin -- a down-sync when jpilot launches, and a full push-up + down-sync right after every HotSync -- with no manual sync command needed day to day. One-time setup requires creating a free Microsoft 365 app registration, which /opt/local/share/palm365-mac/setup.py walks through. Not installable alongside palmgoogle-mac -- both are full-rebuild engines against the same Palm databases, and running two independent ones at once is a real hazard, not a supported configuration.
