Exchange Online Kiosk is Microsoft 365’s most limited email licence, designed for simple email use on a phone or tablet rather than full desktop Exchange functionality.
What works with Kiosk
If you use Microsoft’s own Outlook app on your phone or tablet, the Kiosk licence works well via Exchange ActiveSync, which synchronises email, contacts and calendar – giving you an experience similar to a regular Exchange account, but only on mobile devices.
If you want to use a Kiosk account on a computer, or on a phone or tablet without the Outlook app, you can add it manually using POP3 and SMTP settings instead. Note that this limits synchronisation to email only – contacts and calendar will not sync.
You cannot add a Kiosk account as an Exchange account in desktop Outlook. For full desktop functionality, including calendar and contact sync, you need a more complete licence such as Microsoft 365 Business Basic.
