Office 365 tenant must be version 15.0.000.0 or higher for the hybrid deployment to function correctly with Exchange 2013.
To verify the version and status of your existing Office 365 tenant, do the following:
- Connect to the Office 365 tenant using remote Windows PowerShell
- After connecting to the Office 365 tenant, run the following command:
Get-OrganizationConfig | Format-List AdminDisplayVersion,IsUpgradingOrganization
3. Verify that your Office 365 tenant and status meet the following requirements :
- AdminDisplayVersion parameter value is greater than 15.0.000.0
- IsUpgradingOrganization parameter value is False
For example, “0.20 (15.0.500.5)” and “False”.
Good Luck!
