Issue: Calendar Events and Appointments not syncing

If events from external calendars (Outlook365/Google/Zoho CRM/Zoho Calendars) are not syncing with Zoho Bookings calendar and appointments are not syncing with external calendars, you can reauthorize the calendar sync.

You might have to reauthorize the O365 calendar sync for any of the following reasons:
  1. No sync activity for 90 days
  2. User hasn't logged into O365 for 90 days
  3. Password change in O365
  4. Organization policies in O365
  5. Change in location
  6. Changing MFA/TFA
You might have to reauthorize the Google calendar sync for any of the following reasons:
  1. No sync activity for a long period of time
  2. Sync access for Zoho Bookings has been revoked in Google services
  3. Password change in Google services
You might have to reauthorize the Zoho calendar/Zoho CRM calendar sync for any of the following reasons:
  1. Access revoked for Zoho Bookings under Connected Apps in Zoho accounts
  2. Access revoked for all the connected apps while changing the password

Solution: Reauthorize Calendar sync

What does it do? Makes sure idle connections are refreshed and changes made reflect in Zoho Bookings.
The missing items? Reauthorizing makes sure that the sync happens uninterrupted from then on.
Click the more icon next to the desired calendar accounts and select Reauthorize. 


If the sync isn't working yet, try disconnecting the calendar account and adding it again.     
If the appointments and events still don't sync, please reach out to support@zohobookings.com.

 Issue: Unable to authorize Zoho CRM calendar   

There may be instances when your staff will not be able to add their Zoho CRM calendar.

This could happen because of the following reasons:

  • You changed your Zoho account password from Zoho Accounts (https://accounts.zoho.com) and opted to remove device sessions.

  • You terminated an active session from Zoho Accounts.

  • If the admin has not integrated Zoho CRM calendar in his Bookings.

  • If the staff is not added to the Zoho CRM organization.

What do I do?

If you are a Super Admin:

  1. Navigate to Integration > Calendars.

  2.  Disable Zoho CRM calendar integration.

    • If you also have Zoho CRM contact integration enabled:Navigate to Integration > Others

    • Disable Zoho CRM Contact integration.

  3. Once both the integrations are disabled, you can re-enable Zoho CRM calendar integration, and the integration should work.      

If you are a manager or staff, reach out to your super admin to get this corrected.
