"Unable to retrieve Exchange Online Mailbox properties." when attempting to view Exchange Online properties in the Active Roles Web Interface -
설명
When attempting to view Exchange Online properties in the Active Roles Web Interface, the following error message is displayed:
Unable to retrieve Exchange Online Mailbox properties. The possible reasons may be:
- The current user does not have the Exchange Online License.
- Modern Authentication is not enabled for the tenant.
- Exchange Online PowerShell v2/v3 module is not installed.
This error is showing for all users.
The users are licensed.
Modern Authentication is enabled for the tenant.
The necessary Exchange Online PowerShell module is installed. -
원인
CAUSE 1
There is a protocol mismatch in .NET.
CAUSE 2
There is a custom script module that is using the Disconnect-ExchangeOnline cmdlet.
CAUSE 3
Certain versions of Active Roles support Exchange Online PowerShell v2 module and other versions of Active Role’s support v3 Exchange Online. (v7.5.5 and newer versions) Microsoft are deprecating Remote PowerShell (RPS) in Exchange Online, urging a shift to REST cmdlets via the Exchange Online PowerShell v3 module for enhanced security. -
해결 방안
RESOLUTION 1
Add the necessary registry keys on the Active Roles Administration Service host so that .NET leverages the correct protocol.
RESOLUTION 2
Remove the Disconnect-ExchangeOnline cmdlet from custom script modules.
RESOLUTION 3
Exchange Online PowerShell v2 modules may not work in your environment due to changes implemented by Microsoft. If you receive an error message when running the ‘Connect-ExchangeOnline’ cmdlet via PowerShell, please reach out to Microsoft (to extend support for v2) or upgrade to a newer version of ARS that supports v3. -
