Add Multiple Email Accounts to Outlook on Windows 11
Configure your business and personal Gmail accounts in the desktop version of Outlook to view all calendars in one place.
Microsoft Outlook for Windows allows you to connect multiple email addresses into a single profile. This feature enables you to manage your business domains and personal Gmail calendar simultaneously without needing to switch between different applications.
Open Outlook on your Windows 11 PC, click on the 'File' tab in the top left corner, and select 'Add Account'.
Enter your first business email address, click 'Connect', and enter the password when prompted. Repeat this process for your second business domain.
Click 'Add Account' again, enter your Gmail address, and click 'Connect'. A Google sign-in window will appear; follow the prompts to grant Outlook access to your Gmail account.
Navigate to the 'Calendar' view by clicking the calendar icon at the bottom left of the Outlook window. You can check the boxes next to each account in the folder pane to view them side-by-side or overlaid.

Set Up Outlook Accounts on iPhone
Use the Outlook mobile app on your iPhone to keep your multiple calendars synced on the go.

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.
