Hello @Davidn,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
Regarding your questions, I understand that you are seeking to transition your church's email system from Outlook and Microsoft 365 to Google Workspace while retaining the Microsoft 365 subscription and email services. You also aim to continue managing emails through the Microsoft Admin Center and inquire whether they need to purchase another domain for this transition.
Yes, it is possible to use Google Workspace for email while keeping Microsoft 365 subscription and email for other purposes such as file storage, collaboration tools, etc. You can configure your domain's DNS settings to route email traffic to Google Workspace for email while keeping other services associated with Microsoft 365.
I enlist few outlines of what you can do:
- Set up Google Workspace for email by signing up for Google Workspace and configure your domain's MX records to point to Google's mail servers. This will ensure that emails sent to your domain are routed through Google Workspace.
- Keep Microsoft 365 subscription to maintain your subscription for Microsoft 365 and continue using other services like SharePoint, OneDrive, Teams, AD, etc.
- Manage emails from Microsoft Admin Center though, your primary email service will be through Google Workspace, you can still manage other aspects of your domain, including user accounts, DNS settings, etc., from the Microsoft 365 admin center.
- No need to buy another domain, continue using your existing domain with both Google Workspace and Microsoft 365. You'll just need to configure the DNS settings appropriately to ensure that email traffic is routed correctly.
- Regarding managing emails from Microsoft Admin Center, while you can manage some aspects of your domain's email settings, such as DNS records, user accounts, etc., you'll primarily manage email accounts, settings, and configurations within the Google Workspace Admin console for the email accounts hosted on Google's servers.
I hope this is helpful! Do not hesitate to let me know if you have any other questions.
