Starting October 2022 we introduced a new option for the mailbox type, called Microsoft Exchange / Microsoft 365 / Outlook. All of these refer to the exact same thing: the email service provided by Microsoft to the subscription product families Microsoft 365 Business, Microsoft 365 E3/E5/F3 and Microsoft 365 Education for Schools (as per the names used at the time of this writing: October 1st, 2022). This email service is called Exchange which is not to be confused with the product also called Microsoft Exchange which refers to the self-hosted email server and is typically accessed through the online service called Outlook which is not to be confused with the product also called Microsoft Outlook and which refers to the mobile or desktop email application. If this sounds insanely confusing blame Microsoft for using the same name for radically different, unrelated, and incompatible things — and not sticking with a name for more than 2 years.

OK, here's how to figure out if this feature is for you. Are you a business, enterprise or educational institution? Are you paying Microsoft for some Office and email? Do you have access to the online versions of Word and Excel in office.com? Can you read your business, enterprise, or school email through office.com from the sidebar tab called Outlook OR through the domain outlook.office.com? Are you an administrator for that Microsoft subscription? If you answered Yes to everything: this is the feature you need to use to integrate Akeeba Ticket System with your business or school email.
