I usually go to outlook.office365.com/ecp to update my group distribution list but when I go to it, I'm getting an error #400. How do I get there now? Has it changed?

    Hi @Janine Hollingsworth

    Yes, it was replaced by (EAC).

    The Exchange admin center (EAC) is the web-based management console in Exchange Server that's optimized for on-premises, online, and hybrid Exchange deployments. The EAC was introduced in Exchange Server 2013 and replaces the Exchange Management Console (EMC) and the Exchange Control Panel (ECP).

    The currently supported versions are exchange 2016 and 2019. If your on-premises server has a lower version, it is recommended that you upgrade ASAP.

    Hi @Janine Hollingsworth

    Just adding some info, just in case.

    In the new EAC, navigate to Recipients > Groups > Distribution list.

    Use the Exchange admin center to manage distribution list groups
