The problem
This is the single most common calendar conflict: your work runs on Microsoft Outlook / 365, your personal life runs on Google Calendar, and neither knows about the other. Your partner books a family dinner at 6pm, but your boss just scheduled a late meeting at the same time. You find out when it's too late.
Common issues
- Your work Outlook doesn't see personal Google Calendar events, so meetings get scheduled during personal commitments
- Your personal Google Calendar doesn't know about work meetings, so you accidentally double-book personal time
- Microsoft and Google don't offer native cross-platform calendar sync
- Subscribing to Outlook's iCal feed in Google (or vice versa) is slow and one-way
What people try
People try subscribing to their Outlook calendar in Google, publishing their Google Calendar and subscribing in Outlook, using third-party tools like Zapier or Power Automate, or manually creating busy blocks in both calendars.
Why manual approaches fail
Cross-platform subscriptions refresh too slowly (hours, not minutes). Zapier and Power Automate add complexity and cost, and still have latency. Manual busy blocks are the most common approach but they're tedious, error-prone, and the first thing you forget when you're busy.
How iambusy solves this
iambusy connects your Outlook and Google calendars via their iCal feeds. Publish your Outlook calendar's iCal URL and grab your Google Calendar's secret iCal address. Paste both into iambusy and busy time flows between them in seconds. Use Busy-only mode to keep work details private from your personal calendar and vice versa.
Connect your calendars
Paste the iCal URL from each calendar. Takes 30 seconds per calendar, no passwords required.
Set your sync rules
Choose what to share — full details, titles only, or just Busy blocks to keep things private.
Stay in sync automatically
Changes propagate in seconds. No manual work, no double bookings, no missed meetings.

Frequently asked questions
Will my employer see my personal Google Calendar events?
No. iambusy's Busy-only mode only shows 'Busy' blocks. Your employer sees that you're unavailable but not why.
Will my personal Google Calendar show work meeting details?
Only if you want it to. You can choose Busy-only mode, title-only mode, or full details for each sync direction independently.
Do I need my IT department's permission?
Usually not. Most Microsoft 365 organizations allow users to publish their calendar's iCal feed. If your org blocks this, check with your IT admin.
How fast does the sync happen?
Changes typically sync within seconds — fast enough to prevent someone from booking a slot that was just taken.
