Guides for syncing Google Calendar, Outlook, and iCloud. Setup walkthroughs, comparisons, and answers to questions people actually ask us.

Calendar sync sounds like it should be simple, and then you try to do it across two providers and discover a dozen small ways it goes wrong. An event edited on one side that won’t update on the other. A duplicate that appears every time a meeting moves. A personal appointment that shows up, title and all, on a calendar your whole team can read. The posts here are written to fix the specific problem you searched for, not to sell you on the idea of sync in the abstract.

They fall into a few groups.

Step-by-step setup guides walk through connecting two specific providers and getting events flowing the right direction. If you came here to sync Google Calendar with Outlook, sync iCloud with Google Calendar, or sync a shared Outlook calendar with Google, start there. There are also guides for the smaller jobs that trip people up, like subscribing to an ICS feed in Google Calendar or in Outlook.

Honest comparisons put Hetk next to the tool you might be choosing between, including the best calendar sync tools in 2026 and head-to-heads like Hetk vs SyncGene and Hetk vs Cal.com. Where another tool does a job better, the post says so.

Troubleshooting covers the errors that stop people mid-setup, like the admin-approval message when connecting Outlook, which looks alarming and is usually a two-minute fix.

The thinking behind Hetk is here too, including how we keep work and personal calendars separate but synced and why Hetk has no AI features even though we build it with AI.

Most of these started as a question someone emailed support, or a thread we found where people were stuck. If your situation isn’t covered, write to support@hetk.io. Good questions tend to become the next post.
