Each Add to Calendar creates Multitude of calendar in Outlook

Hi,

Multitude calendars in Outlook or Google calendar? Whichever calendar, unfortunately we can do anything here, it all depends on the import feature of the calendar where you import events, not our calendar.

Thanks,
Ben

And that Ben,

Belies the difference between an import process and a synchronisation process as noted elsewhere.

Import (certainly conventionally) is a one-shot addition to what is already there. Synchronisation (one or bi-directional) has inherently got some cognisance of matching up what is coming with what is already here.

Ai1EC offers inbound synchronisation.
