Office 365 Sign In: Login Steps for Email and Portal

To sign in to Office 365, open {site}, select Sign in, and enter the email address and password connected to your Microsoft account. Use your work or school email if an employer or educational institution provides the account.

The same sign-in process normally opens Office 365 email, apps, and the account portal, but the available services depend on permissions set by the organization that manages the account.

Where is the official Office 365 sign-in page?

Use {site} when you need the verified Office 365 login page. Select Sign in and let Microsoft direct you to the correct account screen.

Office.com is the general starting point for Microsoft Office services. It can lead to email, documents, and other tools available to your account. Outlook on the web is the email-focused service, so it may open the mailbox directly instead of showing the broader Office portal.

Type only the recognized Office.com service name into the browser address bar. Do not enter your password on a page reached through an unexpected message, advertisement, or unfamiliar address. If a saved bookmark behaves strangely, return to the verified site rather than trusting the bookmark.

How do I log in to Office 365 step by step?

1. Open the verified Office 365 sign-in page and select Sign in.
2. Enter the email address assigned to the account. For an Office 365 email login, this is often a work or school address rather than a personal email address.
3. Select Next. If Microsoft asks which account type to use, choose Work or school account for an organization-managed account or Personal account for your own Microsoft account.
4. Enter the password for the selected account. Passwords are case-sensitive, so check capitalization and make sure the phone or computer is using the expected keyboard.
5. Select Sign in. If asked whether to stay signed in, choose based on whether the device is private and trusted. Do not stay signed in on a shared or public device.
6. Complete any identity check shown on the screen. A verification code is a temporary code used to confirm that the person signing in controls an approved phone, email address, or authentication app.
7. After verification, select Outlook for email or choose another available Office service from the portal.

If a code is requested, use only the verification method displayed for that account. Never give the code to another person. If the code does not arrive, check whether the phone number or backup email shown in masked form is familiar, then use another verification option if the screen offers one.

How do I sign in to Office 365 on a mobile phone?

On a phone, you can sign in through a mobile browser or through the Outlook or Office app already installed from your device’s official app store. The browser opens the web version, while an app keeps the account connected on the device and may use device notifications for approval prompts.

1. Open Outlook when the main goal is Office 365 email login, or open the Office app when you need the broader set of services shown for the account.
2. Select Add account or Sign in.
3. Enter the work, school, or personal Microsoft email address associated with Office 365.
4. Enter the password and complete any verification request.
5. Approve any organization notice only after confirming that the account belongs to that employer or school.

If the app repeatedly returns to the sign-in screen, try signing in through the phone’s browser. A successful browser login can show whether the problem is with the account or only with the app. On a shared phone, use the browser’s private mode and sign out when finished.

What should I do if I cannot sign in to Office 365?

An Office 365 log-in failure can come from the password, the account status, the selected account type, or an organization’s security rules. Read the exact message before trying again.

• Incorrect password: Retype it carefully, check Caps Lock, and confirm that a password manager did not fill credentials for a different Microsoft account.
• Wrong account type: Go back and select Work or school account if the email was issued by an employer or educational institution.
• Locked or disabled account: Stop repeated attempts. A work or school administrator may need to unlock, restore, or enable the account.
• Verification problem: Choose another method shown on the screen. If every listed method is outdated or unavailable, contact the account administrator.
• Employer or school access problem: Contact that organization’s IT help desk. Microsoft cannot independently change permissions controlled by the organization.
• Browser problem: Close extra sign-in tabs, try a private browsing window, or clear stored Microsoft sign-in data before trying again.

How do I reset a forgotten Office 365 password?

On the Office 365 sign-in screen, enter the account email and select the option labeled Forgot password or a similar recovery choice. Follow the prompts shown for that specific account.

Password recovery may require a code sent to a previously registered phone or backup email, approval through an authentication app, or information required by the organization. The available method depends on how identity verification was set up before access was lost.

1. Confirm that the displayed email is the account you want to recover.
2. Select the password-recovery option on the sign-in screen.
3. Choose an available identity-check method.
4. Enter the code or approve the prompt.
5. Create a new password that meets the requirements displayed on the page.
6. Return to the Office 365 sign-in page and log in with the new password.

If no usable verification method appears for a work or school account, ask the organization’s administrator to reset the password or update the recovery information. Do not use a third-party access-recovery service.

How do I sign in with an Office 365 work or school account?

A work or school account is created and managed by an employer, school, college, or other organization. A personal Microsoft account is created and controlled by the individual, even when both accounts use the same email address.

• Work or school account: Use the email and temporary or permanent password provided by the organization. The administrator controls access, security requirements, and available Office services.
• Personal Microsoft account: Use the credentials and recovery methods set by the individual account owner.

If Microsoft shows both account types, select the one connected to the Office 365 access you need. When an organization issued the email address or sign-in instructions, choose Work or school account. If access was never issued, only that employer or educational institution can confirm eligibility and create the account.
