One booking page, two calendars: Google and Outlook together
Got a work Outlook calendar and a personal Google one? Connect both so clients only see times that are free in each.
Lots of people need to schedule across Google Calendar and Outlook. The day job lives in a Microsoft 365 work calendar, while the side business, the kids' sport and the gym sit in a personal Google calendar. Neither calendar knows about the other, so a client who books from one view can land right on top of a commitment in the other.
This guide shows how to run one booking page across both: connecting both calendars, checking both for conflicts, deciding where new bookings should land, and keeping work and personal details appropriately separate. It suits sole traders with a day job, portfolio workers and consultants who hold client accounts.
How does scheduling across two calendar providers work?
Google Calendar and Microsoft Outlook are separate systems. Out of the box, your Outlook calendar can't see your Google busy times, and Google can't see Outlook's. Colleagues checking your availability in Outlook only see your work commitments, and the same goes the other way.
A booking tool can bridge the gap by connecting to both. Calenix lists Google Calendar and Microsoft Outlook among its calendar integrations, where enabled. When both are connected, Calenix checks each for busy times and only offers slots that are free in both. That's the core of it: one booking page, two sources of truth, no clashes.
What your plan allows
- Free: one connected calendar. You'd need to choose Google or Outlook, so this plan suits people who can consolidate.
- Individual: up to six connected calendars, which comfortably covers a work Outlook, a personal Google and a couple of extras.
Checking versus writing
Two separate questions come up with more than one calendar. First, which calendars should be checked for conflicts? Usually all of them that hold real commitments. Second, which calendar should new bookings be added to? Usually the one that matches the work, such as your Google calendar for a side business. Check your Calenix settings for which calendar new bookings are added to, and make it a deliberate choice rather than a default you never looked at.
What gets shared
Checking a calendar for busy times isn't the same as publishing its contents. Clients see available slots on your booking page, not what you're doing the rest of the time. Your employer's policies still apply to connecting a work account, and your IT administrator may need to approve it. For each side on its own, see our guides to syncing Outlook with your booking page and syncing your booking calendar with Google Calendar.

Why two unconnected calendars cause trouble
With two calendars, most clashes come from the gap between them. A colleague books a 3pm meeting in Outlook, and an hour later a client books 3pm through a booking page that only checks Google. Neither person did anything wrong; the systems just didn't talk.
People try to patch this by hand. The usual trick is copying events across as 'busy' blockers. It works for a week, then a meeting moves in Outlook and the blocker in Google doesn't. Another approach is subscribing to one calendar inside the other using a calendar feed. That shows events, but subscribed feeds can refresh slowly and aren't always treated as busy time by booking tools, so it's not something to rely on.
Connecting both calendars directly removes the manual step. Conflict detection runs against both sources, so the booking page reflects your real day, and changes made in either calendar flow through without you lifting a finger. Our guide to syncing bookings with Google Calendar automatically explains what happens when events move or get cancelled. For how this works under the hood, including all-day and tentative events, see our explainer on how calendar sync prevents double bookings.
There's also a relationship benefit. When clients can see accurate times and pick one themselves, you stop the back-and-forth of offering slots you then have to withdraw. Our guide to scheduling meetings without email ping-pong covers the wider habit change.
Benefits of connecting both calendars
No clashes between work and personal: slots only appear when both calendars are free.
No manual blockers: you stop copying events between Google and Outlook by hand.
Bookings land where they belong: choose a calendar that matches the work being booked.
Privacy kept intact: clients see free times, not the contents of either calendar.
Room to grow: Individual allows up to six calendars if you add a shared or team calendar later.
Less mental load: you trust the booking page instead of double-checking two apps.
How to schedule across Google Calendar and Outlook in 6 steps
List every calendar that holds real commitments — Write down your work Outlook, personal Google and any secondary calendars, such as a family or on-call calendar, and note which ones should block client bookings.
Check your plan and your employer's policy — Free covers one connected calendar and Individual covers up to six. If one account is a work Microsoft 365 account, check whether IT needs to approve the connection.
Connect both accounts in Calenix — In your Calenix settings, connect your Google account and your Microsoft account, approving the access each provider asks for.
Choose which calendars are checked — Make sure every calendar with genuine commitments is included in conflict checking, and leave out calendars that only hold reference information such as public holidays.
Decide where new bookings are added — Check your Calenix settings for which calendar new bookings are added to, and pick the one that matches the work, such as Google for a side business.
Test from both directions — Add a busy event in Outlook and another in Google, then check both times disappear from your booking page. Book a test slot and confirm it lands in the calendar you chose.

Best practices for scheduling across two calendars
Check every calendar that holds real commitments, not just the one you look at most.
Add bookings to the calendar that matches the work, not whichever was connected first.
Use Outlook's 'Free' or Google's 'Available' setting for events that genuinely shouldn't block you.
Set availability rules in Calenix that reflect your real working pattern across both jobs.
Keep time zones consistent across both accounts, especially if you travel or work interstate.
Review connected calendars whenever you change jobs or add a new account.
Common mistakes to avoid
Connecting only your personal Google calendar and forgetting your work meetings.
Staying on a one-calendar plan and hoping manual blockers will keep up.
Letting side-business bookings land in your work calendar where colleagues can see them.
Connecting a work account without checking your employer's policy on third-party apps.
Leaving a former employer's calendar connected after you move on.
Relying on subscribed calendar feeds for conflict checking.
Example: a part-time bookkeeper in Brisbane with a day job
Take a bookkeeper in Brisbane who works three days a week for a Sydney-based firm and runs her own bookkeeping clients on the other two days and some evenings. Her employer uses Microsoft 365, so her work diary is in Outlook. Her side business, family life and netball training live in a personal Google calendar.
At first she used the Calenix Free plan with only Google connected. It worked until a client booked a Tuesday lunchtime call that clashed with a team meeting her manager had moved in Outlook. She'd been copying work meetings into Google by hand and had missed that change.
She moved to Individual and set things up properly:
- Both calendars connected: her work Outlook, with IT's approval, and her personal Google calendar.
- Both checked for conflicts, so work meetings and family commitments block her booking page.
- New bookings added to Google, keeping client names out of her work calendar.
- Availability rules offering Monday, Friday and weekday evenings from 6pm to 8pm.
Time zones needed one extra thought. Queensland doesn't use daylight saving, so from October to April, Sydney on AEDT is an hour ahead of Brisbane on AEST. Invites from the Sydney office are created in Sydney time, so she made sure both accounts and her Calenix availability were set to Brisbane time.
Illustrative maths: if a clash costs her one A$120 client session a month, that's A$1,440 a year, and more in goodwill. Since connecting both calendars, she hasn't copied a single blocker, and her clients only ever see times she can genuinely do.
