iPhone not recognizing my Microsoft account when I try to add Outlook to my iPhone calendar.

Hello,

I am trying to sync my work outlook to my google and iPhone accounts. Both have asked me to sign in to my Microsoft account. Google recognized my work email address and allowed me to add the Outlook calendar to my Google calendar, but when I try on my iPhone, Microsoft says "That Microsoft account doesn't exist. Enter a different account or get a new one." I sign in to this Microsoft account all the time, so I know it exists.

Thanks for your help,

Treble

    Hi TrebleC,

    Thank you for reaching out. Before we proceed, could you please let me know if you are trying to add the calendar manually via Exchange （using the native iOS Calendar） or if you are using the Outlook app?

    May I know if you tried to use the Outlook App, but first you need to:

    • Download the Outlook app from the App Store.
    • Open Outlook and tap "Add Account."
    • Enter your work email address and tap "Continue."
    • Complete the Microsoft login process, including MFA if required.
    • Once added, enable calendar syncing in Outlook by tapping the Calendar tab (bottom-right) and selecting "Sync" if prompted. Sometimes adding the account directly through the Outlook app on your iPhone will help.

    For quick advice on how to fix this issue, please contact the :  Get in-app help for Outlook for iOS and Android - Microsoft Support.  Microsoft has a dedicated support team for each product, and the in-app support team has resources and specially trained engineers to troubleshoot your issue.

    Hello Albert,

    I'm trying to add the Outlook calendar through the Calendar Settings on the iPhone. I can't download the Outlook app because my iOS is too old.

    Thanks,
