O365 Calendar – Troubleshooting Meeting details not appearing on the Hub

When you integrate the O365 calendar with Zoapi, you might sometimes not see calendar events on the Zoapi Hub. This issue may occur because, by default, O365 configures all room resources to:

  • Remove meeting details
  • Replace the meeting subject with the organizer’s name

As a result, the Zoapi Hub does not receive any calendar details and cannot display meeting information.

To solve this, you need to run a few powershell commands on Exchange:

1. Open a PowerShell(as administrator) with the Account/Exchange Admin account:
Sign in to the Exchange Admin console ( and click on the Cloud Shell Icon on the top right:


Sign into Azure Portal ( and open the cloud shell from the top right icon:

If you don’t have an account, create a free account with the Account Administrator login.


You can also access Exchange Online Powershell from a Powershell console on your local computer. Follow the instructions provided in the Microsoft Article Connect to Exchange Online PowerShell | Microsoft Docs

2. On the shell, enter the following commands one at a time (Replace <roommailid> with the room resource email id):

Install-Module -Name ExchangeOnlineManagement

Import-Module ExchangeOnlineManagement


Set-CalendarProcessing -Identity <roommailid> -DeleteSubject $False – AddOrganizerToSubject $False -DeleteComments $False

For more information, please review the Microsoft documentation available at Exchange Online PowerShell
