Can I sync with Exchange?

BusyCal and BusyContacts are compatible with Exchange 2007 SP3 and later, but BusyMac recommends Exchange 2013, which is more reliable than older versions.

Note: This FAQ covers legacy Exchange/EWS connectivity. For outlook.com and Microsoft 365 personal/home accounts, use Office 365 (Microsoft Graph).
