I am using Outlook for my work email and it's functioning just fine on my laptop; I've also had the email on my iPhone for months. Suddenly the account was not updating, so after trying a few fixes, I had to delete the email account from my iPhone - now when I'm trying to reinstall it, it is saying my Microsoft account doesn't exist . . . when I am logged in on my computer, and it very much does exist. Any suggestions?

    Hi @Stacey Mayer

    Welcome to our forum!

    Looks like the issue is more related to Outlook for mobile. Please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. In order to better solve your problem, it's suggested to post your issue on this dedicated forum for Outlook for Mobile for more professional help. 


    In addition, here are some steps you may take:

    1. Verify Your Account Credentials
      • Double-check that you're entering the correct email address and password when adding the account to your iPhone.
      • Ensure there are no typos or extra spaces in the email address.
    2. Check for Account Lock or Security Issues
      • Sometimes, Microsoft accounts can be temporarily locked due to unusual activity. Log in to your account on a browser and check for any security notifications or prompts to verify your identity.
      • Visit the Microsoft Account Recovery Page if you suspect the account might be locked.
    3. Check for Device or App-Specific Issues
      • If you're using the native Mail app on iPhone, try using the Outlook app instead (or vice versa).
      • Restart your iPhone and try adding the account again.

    Thanks for your support and understanding!
