How to share availability in Outlook (when you use Google Calendar)
Many threads mix Google Calendar on your side with Outlook or Microsoft 365 on theirs. You do not need them to open a Google appointment page, and they do not need access to your calendar.
Plain-text availability in the email body works in Outlook the same way it works in Gmail: they read the times, check their calendar, and reply. After they pick, either of you can send a meeting invite from your own calendar product.
Steps
- 1
Generate free times from Google Calendar
Stay in your source of truth. List only times that are free on Google Calendar for the range you are offering.
- 2
Write the email for an Outlook reader
Use a clear timezone label and day-per-line formatting. Outlook users often scan on desktop mail; keep the list easy to quote in a reply.
- 3
Send from whatever mail client you use
Whether you send from Gmail, Outlook, or another client, the body content is what matters. The recipient’s Outlook calendar does not need a special link to understand “Tue 2–4pm Eastern.”
- 4
Let them reply with a choice
Ask them to reply with one slot. They can check Outlook availability on their side without you sharing free/busy permissions.
- 5
Send a calendar invite both systems understand
After agreement, send a normal meeting invite (Google Calendar or Outlook). Standard calendar invites interoperate widely; you do not need a third-party booking page for a single meeting.
Example message to an Outlook user
Example only — sample times, not live calendar data. Copy and adapt.
Hi Jordan, Here are some times that work on my calendar (all Eastern): Tue (3/4): 9–11am Wed (3/5): 1–3pm Fri (3/7): 10am–12pm If one of those works for 45 minutes, reply with your pick and I will send a calendar invite. Best, Sam
Frequently asked questions
Do I need to share my Google Calendar with their Outlook?
No. Sharing calendars across organizations is often blocked or overkill for a single meeting. Pasting free times avoids permission setup.
What about Microsoft Bookings or scheduling polls?
Those tools help when you want self-serve booking or group voting inside Microsoft’s ecosystem. For a simple “here are my openings,” text in the email is enough.
Will my timezone abbreviation confuse Outlook users?
Spell out the zone once (“Eastern Time / ET”) and keep all listed times in that zone. Consistency matters more than which product they use.
Can they still send the Outlook invite?
Yes. Either side can create the meeting once the time is agreed. Decide who owns the invite in your closing line if that matters for rooms or dial-in details.
