Blackberry Desktop Manager and Windows 7 - Spiceworks Community

Modern wireless sync is slow and unreliable. In 2012, RIM allowed you to sync your Outlook calendar and iTunes playlists over local Wi-Fi without a BES server. DM 7.1 B042 is the last version where this feature functioned without requiring a BlackBerry ID login (servers that are now mostly defunct).

Open Desktop Manager. If it detects your device PIN, you’re done. If not, try a different USB port (USB 2.0 ports work better than USB 3.0 for legacy devices).

If you are using Microsoft Outlook 2013, 2016, 2019, or 365 (even 32-bit), this version of Desktop Manager will not sync using the native MAPI protocol. You can still use it for backups, application loading, and media transfers, but calendar/contact sync requires an intermediate solution (like exporting to CSV and using legacy Outlook 2010 in a VM).
