To use a custom domain you need more steps and knowledge. I recommend getting a consultant near you. He or she will setup your environment in about 1 to 3 hours. Depends if all the functionality you need. More on reddit.com

People also ask

Is Outlook email free for business?

Microsoft Outlook offers a free plan, but it doesn’t come with a custom domain (only an @outlook.com one), which may not be suitable for business use. It also only accommodates one user. Microsoft 365’s business plans start at $6 a month and let you use a custom email domain (e.g., [email protected]) and add multiple users to your organization. It also comes with the Microsoft Office productivity suite, including Word, Excel, and PowerPoint.

Should I use Outlook or Gmail for business email?

Use Outlook for your business email if you need a lot of email and cloud storage. Microsoft provides up to 50GB of mail storage and 1TB of cloud storage on all its Business plans. It’s also a good option for more productivity tools like a collaborative workspace or online video editor. Choose Gmail if you want an easier setup process and beginner-friendly interface or are more familiar with the Google Workspace productivity suite.
