Outlook 365 Login: How to Sign In

To sign in to Outlook 365 now, open {site}, select Sign In, and enter the Microsoft work or school account connected to your mailbox. After Microsoft verifies your password and any security prompt, select Outlook from the app launcher to reach your inbox.

Where do I sign in to Outlook 365?

For an Outlook 365 sign in, use {site} and select Sign In. If the Microsoft 365 home page appears after login, open the app launcher and select Outlook.

Outlook on the web is the browser version generally used with a work or school account. Outlook.com is for personal Microsoft accounts, including Outlook.com, Hotmail, Live, and MSN addresses. If the wrong mailbox appears, sign out and start again with the correct account.

Avoid pages reached through unexpected messages or ads. A genuine Outlook login 365 page is part of Microsoft's sign-in process and does not ask you to send your password or verification code to another person. If the page looks unfamiliar, close it and begin again from the verified site marker on this page.

How do I complete the Outlook 365 sign-in steps?

1. Open the official Microsoft 365 sign-in page using the verified site marker.
2. Enter the complete email address or username provided by your employer or school, then select Next.
3. Confirm that the account shown is the one connected to the mailbox you need.
4. Enter the password and select Sign In.
5. Complete any verification request, such as an authenticator approval or security code.
6. When asked whether to stay signed in, choose Yes only on a private device you control. Choose No on a shared or public device.
7. If the Microsoft 365 home page opens, select the app launcher and then Outlook. The inbox should load.

Search phrases such as “outlook 365 online login,” “outlook 365 login email,” “outlook email sign in 365,” “outlook 365 email log in,” and “login for outlook 365” all refer to this basic process. Even if you searched for “out look 365 login” or “outlook 365 email login in,” enter credentials only in Microsoft's official sign-in flow.

How do I fix common Outlook 365 sign-in errors?

• Wrong password: Check Caps Lock, keyboard language, and accidental spaces. If a saved password is being inserted, remove it and type the current password manually.
• Account locked: Follow the recovery instructions shown on the Microsoft screen. For a work or school account, contact the organization's IT administrator if self-service recovery is unavailable.
• Account does not exist: Check every character and the part after the at sign. Make sure you are using the work or school address assigned to the mailbox rather than a personal Microsoft address.
• Page keeps reloading or stays blank: Close extra Microsoft tabs, try a private browsing window, or clear cookies and cached site data for Microsoft pages. You can also try another current browser.
• Wrong account opens: Sign out of every Microsoft account in that browser, close the browser, reopen it, and complete the Outlook 365 login sign in with the intended address.

How do I reset a forgotten Outlook 365 password?

Start at the Microsoft sign-in screen and select Forgot password or Can't access your account. Enter the email address for the mailbox and follow the identity-check prompts.

Microsoft may ask you to confirm part of a recovery email address or phone number and then enter a code. A work or school account may use security information established by the organization. Self-service password reset must be enabled by the administrator; if it is unavailable, the screen may direct you to contact the administrator.

Create a new password after identity verification succeeds, then repeat the Outlook 365 log in. Microsoft support representatives cannot provide a password-reset link manually or change protected account details for you.

What should I do if the verification code never arrives?

A verification code is a temporary number used to confirm that the person signing in controls a registered email address, phone, or authentication method.

• Check the correct email inbox, including its junk folder, or confirm that the selected phone can receive messages.
• Make sure the masked recovery details on the screen match a method you recognize.
• Do not request codes repeatedly in quick succession, because repeated attempts can trigger a temporary security block.
• If an authenticator prompt does not appear, open the authenticator app directly and check for a pending request. Confirm that the phone has a working connection and the correct date and time.
• Select another verification method if Microsoft offers one. If none of the displayed methods is available, use the account recovery or sign-in helper option shown by Microsoft.

Never approve an authenticator request or share a code when you did not initiate the Outlook email 365 login yourself.

How do I sign in through the Outlook mobile or desktop app?

In a mobile browser, the Outlook 365 email login follows the same web steps, although menus may appear under a compact icon. In the Outlook mobile app, select Add Account or Sign In, enter the complete email address, and follow the Microsoft password and verification screens.

In the Outlook desktop app, open the account settings or choose File, then Account or Office Account, and select Sign In or Add Account. Enter the work or school account associated with Outlook 365. An organization may require additional security or device-management steps; follow only prompts supplied through the Microsoft app or your organization's administrator.

How do I get official help with Outlook 365 account access?

Use Microsoft Support and choose the sign-in helper for an account-access problem. The helper checks the account information you provide and gives recovery steps. For technical assistance, describe the problem in Get Help and select Contact Support if that option is offered.

For an employer or school mailbox, contact the organization's IT help desk or Microsoft 365 administrator. The administrator can confirm the username, account status, and available reset process, but no legitimate helper should ask you to reveal your password or verification code.
