I'm currently raising a startup company that's using an ISP's services. All we have at this time is IMAP for e-mail. And we're using JIRA/Confluence.
I want to migrate us to a comprehensive infrastructure, using domain accounts for our Windows 10x64 machines, e-mails, shared calendars, shared contacts (i.e. Exchange Server features), Azure DevOps, MS Teams, SharePoint etc.
I did some research, but I couldn't find any information explaining on how to do that, particularly regarding using Outlook 2019 with Azure. When it's about Azure AD, I only find information on how to synchronize a local domain to Azure, but no information on how to easily utilize Azure as a replacement for a domain controller.
As a start, I would need to know what to do in order to create a domain on Azure (i.e. using Azure as a domain controller), migrate our domain name to Azure AD and to get Exchange Server features running in Azure, so we can use Outlook 2019 on their machines.
