Troubleshooting problems with remote operations in PowerShell (specifically regarding about_Remote_Troubleshooting)

Resolution:

Important Note:
We have introduced a new and improved method for automatically configuring Exchange Online connectors in Sigsync. This updated approach eliminates the use of the legacy RPS protocol

The issue arises due to an unexpected policy update by Microsoft for Exchange Online. This update affects all Microsoft 365 tenants created on or after April 1, 2023, as it now blocks Remote PowerShell (RPS) connections. It's worth noting that our connectors configuration wizard relies on the RPS protocol, which explains the compatibility issue.

To resolve this issue, you can restore the functionality of Remote PowerShell (RPS) in your Microsoft 365 tenant by following the steps outlined below.

Re-enable Remote PowerShell (RPS) in the Microsoft 365 admin center

To restore the Remote PowerShell (RPS) protocol for your tenant, follow the steps provided below:

1. Click on the below link provided by Microsoft to access the self-service tool for Remote PowerShell (RPS).

   Link: https://aka.ms/PillarEXORPS

   Note: If you are not already signed in, sign in using your global admin credentials when prompted.

   

2. When accessing the Microsoft 365 admin center, you will find the RPS self-service tool displayed in the right pane. To check the RPS status for your tenant, click on 'Run Tests' as illustrated in the image below.

   

Additional details regarding the deprecation of the RPS protocol are as follows:

Initially, Microsoft had planned to retire the RPS protocol for all Microsoft 365 tenants by June 2023. However, on March 27, 2023, Microsoft released information stating that starting from April 1, 2023, they would block RPS connections for tenants created on or after that date. Despite this, it is still possible to reactivate RPS in those specific tenants* by utilizing the RPS self-service tool (as explained earlier). It's important to note that the self-service tool will be retired on September 1, 2023, and Microsoft will commence the process of disabling RPS in all Microsoft 365 tenants starting from October 1, 2023.

Sigsync is presently in the process of developing a new approach to automatically configure Exchange Online connectors within the Sigsync dashboard. This upcoming method will no longer rely on the RPS protocol and will be implemented well before the scheduled RPS deprecation.

Please be aware that tenants created after July 1, 2023, will have RPS permanently disabled, and it will not be possible to reactivate it using the self-service tool.
