The maintenance is now complete. Thanks for your patience.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

We would like to inform you that from June 15, 2023, Microsoft will only accept connections with at least ExchangeOnlineManagement Module version 3.1.0 from Powershell. For more general information about this, see:

• https://learn.microsoft.com/en-us/powershell/exchange/exchange-online-powershell-v2?view=exchange-ps

• https://www.codetwo.com/admins-blog/update-exo-v3-powershell-module/

• https://www.powershellgallery.com/packages/ExchangeOnlineManagement/3.1.0

Powershell is used in combination with the ZorgMail Domain Book script that is set up on your mail server. The ZorgMail Domain Book script ensures that the domain book transport rules on your mail server remain up-to-date.

What does this mean for me? You must update the ExchangeOnlineManagement Module to at least version 3.1.0. See instructions in the link https://docs.enovation.io/zorgmail/exchange-online-management-module-update
