Sending, receiving, and organizing email in Outlook.com
Hi, I'm John! I will help you with this.
What exactly happens when you try to access Outlook? Are you unable to sign in, unable to receive a verification code, or do you see an error message?
Please share the exact error message if there is one. Also let me know whether you are using Outlook.com in a browser or the Outlook app.
About contacting support:
Are you using a personal Microsoft account (like Outlook/Hotmail), or is this for Microsoft 365 Business?
Phone support is usually available for Microsoft 365 Business accounts. For personal Microsoft accounts, support is typically handled through live chat online or via the Get Help app rather than a direct hotline number.
