Frequently Asked Questions

Can I view my Google Calendar and Outlook business calendar side-by-side?

Yes. Once you add both your Gmail and business accounts to Outlook on Windows 11, navigate to the Calendar view. Check the boxes next to both calendars in the left pane. You can leave them side-by-side or click the left-facing arrow on the calendar tab to overlay them.

Why are my Outlook calendars not syncing to my iPhone?

Ensure that background app refresh is enabled for the Outlook app in your iPhone settings, and that you are actively connected to the internet. If you are using the native Apple Mail/Calendar app instead of the Outlook app, verify that the 'Calendar' toggle is enabled within iOS Settings > Mail > Accounts for each specific account.

Can I manage multiple Microsoft 365 Family accounts on the same computer?

Yes, Outlook allows you to add multiple Microsoft 365 accounts to the same Outlook profile. You simply navigate to File > Add Account and enter the credentials for each additional Microsoft 365 account you wish to manage.
