Frequently Asked Questions

Why isn't my calendar syncing when I use my AOL email address?

If your Microsoft 365 account utilizes an AOL email address as an alias, ensure you are selecting 'Microsoft Exchange' or 'Outlook' when adding the account to your phone, rather than selecting 'AOL'. Selecting AOL will only sync standard emails, not your Microsoft 365 calendar data.

Can I view my Microsoft 365 calendar without downloading the Outlook app?

Yes, you can use the native calendar apps on both iOS and Android. By adding your account through your device settings and selecting 'Microsoft Exchange', your calendar data will populate directly into Apple Calendar or Google Calendar.

How do I force my iPhone calendar to sync updated Microsoft 365 events?

To force a sync, open the Apple Calendar app and tap 'Calendars' at the bottom. Swipe down from the top of the screen to refresh. If it still doesn't sync, go to Settings > Calendar > Accounts > Fetch New Data, and ensure the schedule for your Exchange account is set to 'Push' or 'Fetch'.

What is the difference between Microsoft 365 Family and Business for calendar syncing?

The syncing process is largely identical on mobile devices. However, Business accounts connect to Microsoft Exchange servers via organizational credentials, while Family accounts use personal Outlook.com servers. Both are natively supported by the Outlook mobile app.
