We are a non-profit with approx. 650 users and are in an unfortunate situation. We hired a vendor to get us off our failing on-prem 2010 Exchange server, which they did, but now we have Exchange Online and no connection from our on-prem AD to Azure. We did not find out until after the the fact that our domain level not at a level to connect to AZURE. We are stuck and need direction. Thank you for any information that may help us move forward to moving our environment to O365.
@Lisa K Welcome to the Microsoft Q&A forum, Thanks for posting your question.
This is an AAD issue and requires to properly synchronizing AD with AAD using Azure AD Connect tool ( see Directory synchronization with Azure Active Directory - Microsoft Entra | Microsoft Learn)
