    If the account shows blocked due to unusual activity, use the sign-in flow to verify identity with a security code and unblock it.

    1. On the sign-in screen, follow the unblock prompts and select where the security code should be sent.
    2. Enter the code to regain access.
    3. If the block shows Try another verification method:
      • use a different verification method already connected to the account
      • switch networks, such as Wi-Fi to cellular or another Wi-Fi network
      • stop repeated attempts and wait at least 24 hours; if still blocked, wait longer, up to 1 week
    4. If the Outlook.com account still cannot be unblocked, use Sign-in Helper.
    5. If the mailbox or OneDrive storage is full, email send/receive can also be affected, so check mailbox storage and Outbox.

    If this is specifically in Outlook for iOS or Android and the error appears when adding a second Microsoft 365 account, there is a separate limitation: additional Microsoft 365 accounts must be hosted in the same physical region as the first one added to Outlook Mobile. In that case, there is no workaround.

    Multiple reports of the same problem. e.g.

    https://learn.microsoft.com/en-us/answers/questions/5986835/cant-create-account-microsoft

    https://learn.microsoft.com/en-us/answers/questions/5992695/how-do-i-create-a-new-outlook-email-when-i-keep-ge

    No official acknowledgement of the problem from Microsoft, and no solutions (that I have seen).

    Try Chat Support:

    • Open a browser to https://support.microsoft.com/en-us/home/contact
    • Tell us your problem: {Whatever}
    • [Get Help] {Scroll down to the bottom of the page} [Sign in to Contact Support]
    • Sign in with any Microsoft account
    • Products and services: "Other Products"
    • Category: "Manage Account Security"
    • [Confirm]
    • Choose a support option -> "Chat with a support agent in your web browser"

    Get a friend or relative in another location to try and do the create for you. Make sure they put an "Email a code" 2nd verification on the account. You'll need it when you try to logon for the first time from a different location.

    Please try:

    • Turn off any VPN or proxy.
    • Try a different network, such as a mobile hotspot.
    • Wait a few hours and try again.
    • If the issue continues, use Microsoft’s Sign-in Helper or contact Microsoft Support.
    • Please check your account to another laptop, its working or not.
