Issues connecting to Exchange
If problems are experienced when connecting to Exchange, check the following.
Check OAuth is enabled for Exchange online
An Exchange admin can run the following Powershell commands to determine if OAuth is enabled:
Install-Module -Name ExchangeOnlineManagement Connect-ExchangeOnline -UserPrincipalName adminEmailId Get-OrganizationConfig | Format-Table Name,OAuth* -Auto
If the result shows OAuth2ClientProfileEnabled = False, run the folowing:
Set-OrganizationConfig -OAuth2ClientProfileEnabled $true
Validate access to Exchange Web Services (EWS)
- Open a private browser page (incognito or private mode, depending on browser) and go to https://outlook.office365.com/
- Enter user credentials for the Exchange room when prompted.
If an unauthorized access error is displayed, or the username/password prompt reappears, either the credentials for the Exchange room are incorrect or the account does not have the required permissions.
Check the correct Exchange Web Services (EWS) URL is saved in Calendar Settings
