Your PennyPerfect sessions can be easily synchronised with other applications in just a few clicks.
Outlook can be synchronised both ways. You can import sessions from Outlook and have them created in PennyPerfect, and you can also export your sessions from PennyPerfect and have them created in Outlook.
Maintining multiple calendars is not recommended. You should edit a 'master' calendar and only export from that to the other calendars. Trying to edit and maintain multiple calendars quickly creates calendar conflict.
