I would like to Sync my Microsoft Outlook Calendar to Google Calendar, this is now possible with Version 1.8.1.
I created this small workflow and it works, but the Problem is it will recreate the Calendar Items every Time the Workflow will run (Once a Day) i am not sure how to create a Workflow to check before if the Item already exists and only create it if it’s there.
Building a two way sync can be somewhat complex, but should be possible (as long as there is a unique identifier for each event in your calendars which you can use for de-duplication).
Perhaps you want to take a look at How to synchronize data between two systems – n8n Blog for a possible approach? This article is about CRM systems, but the basic process would also apply to other entities of course.
