Bookem allows a one-way sync to let your Bookem calendar show up on your Outlook and Google calendars, and a one way sync vice versa, i.e. for your external calendar to show up on Bookem. External calendars are read-only.
The synchronisation of your external calendar depends on the update schedules of systems. Google syncs every 24 hours while Outlook syncs every 3 hours. Bookem, however, syncs every 5 minutes with your external calendar - so what you see on your Bookem calendar will be mostly up to date.
Firstly, you need to find your Bookem calendar URL. Go to Settings > Team Members
Select the team member whose calendar you want to sync
Scroll down and click 'Sync with other calendars'
A pop-up window will appear. Focus on the first section: View your bookings on Google Calendar, MS Outlook, and other apps.
Follow the steps, copy your Bookem calendar URL, and paste it into your 3rd party calendar app.
On your browser, go to calendar.google.com
Under 'Other calendars', click the '+' to 'add other calendars'
Select 'From URL'
Now, paste your Bookem iCal export URL and click 'Add calendar'
Here is Microsoft's article on how to do it. Otherwise, here's a quick how-to:
Go to your Outlook calendar in your browser or use the Outlook App
Select the calendar icon in the left column
In the navigation pane, select 'Add calendar'
Select 'Subscribe from web'
Now paste your Bookem URL link to sync your calendar
