Hi Tony,
Email systems can be very confusing as there are essentially 3 different technologies available and also a big difference between personal email and business email. Finally Microsoft have made things even more complicated with their branding of Outlook and Office.
Personal email generally doesn't allow multiple email accounts. So if you have a personal gmail account then you will only be able to have the 1 account.
However, Google offer a business suite called Google Workspace. This is designed for teams.
Microsoft offers 2 products called Outlook. Outlook the email client is a program that is installed on the computer and allows you to access an email account provided by almost anyone including Google.
Microsoft also offer, confusingly, a free personal email account at Outlook.com. But this is very much aimed at the personal market and not designed for business.
For businesses, Microsoft offer a package called 'Microsoft 365 for Business'. Like the Google Workspace this is designed for teamworking and collaboration.
Of course, you could simply have multiple personal email accounts for your team but you wouldn't get any collaboration features such as calendar sharing, shared mailboxes and so on.
I hope that gives a good overview of the email systems out there. Email systems can be very overwhelming which is why most small businesses use experts like us to make it all work for you.
Regards,
Abe
