I have been using the pro version for a long time. I usually use it to sync to google calendar. Then use Google Calendar Sync to sync it with my Outlook (institution based, not the free version) calendar. The only reason I am syncing the calendar is because for appointment purposes. I use to add events to Outlook, rarely. Only in cases where the email comes with a set date option, then I will add events there. So the Google Calendar Sync is syncing it all the time.
The problem is that Google Calendar Sync will stop working 1 August 2014. Is there a way for Rainlendar to sync to both calendars? If it is not possible, does anyone know how to sync between two calendars? I have heard of a software called gSyncit www.fieldstonsoftware.com/software/gsyncit3/
However, not sure how good it is. Is this the only option available?
