The fastest way to sign out of Outlook

To log out of Outlook on your desktop, click your profile picture or initials in the top right corner of the window, then select Sign out from the menu that appears. The process closes when ready and you are no longer signed in. On your next launch, Outlook will ask for your password again.

This works the same way in Outlook for Windows and Outlook for Mac. The profile icon is always in the upper right, and the sign-out option is always the last item in the dropdown menu.

Key Takeaways

  • Click your profile picture or initials in the top right corner and select Sign out to leave your account when ready.
  • Signing out closes the process entirely — you cannot stay in Outlook without being signed in to an account.
  • If you share a computer, signing out prevents the next user from reading your email without entering a password.
  • Restarting your computer does not sign you out; you must use the sign-out menu to disconnect your account.
  • If the sign-out option is grayed out or missing, your account may be managed by your workplace, and you may need to contact IT support.

Why you should sign out instead of just closing the window

Closing Outlook without signing out leaves your account active on that computer. If someone else sits down at your desk or uses your machine, they can open Outlook again and read all your email, calendar, and contacts without entering a password. Signing out removes that access.

This matters most if you share a computer with family members, use a work machine that others access, or work in an office where your desk is not always locked. On a personal computer that only you use, closing the window is usually enough — but signing out takes ten seconds and costs nothing.

What happens after you sign out

Once you click Sign out, Outlook closes completely. Your email, calendar, and contacts are not deleted — they stay on Microsoft's servers and in your account. When you open Outlook again on any computer, you can sign back in with your password and see everything exactly as you left it.

Signing out does not delete any messages, contacts, or settings. It only disconnects your account from that particular computer. If you want to delete email permanently, you must do that before signing out.

Signing out on a shared work computer

If you use Outlook on a work machine that other employees also use, signing out is essential at the end of your shift. Click your profile picture, select Sign out, and wait for the process to close fully before walking away. The next person to open Outlook will see a sign-in screen.

Some workplaces set Outlook to sign you out automatically after a period of inactivity — usually 15 to 30 minutes. Check with your IT department to learn whether your organization has this setting enabled. Even if it does, manually signing out is faster and more reliable.

If the sign-out option is missing or grayed out

On some work computers, your account is managed by your organization's IT department, and the sign-out option may be hidden or disabled. This is common in corporate environments where the company wants to keep email running continuously or prevent accidental sign-outs.

If you cannot find the sign-out option, contact your IT support team. They can either enable the option for you or show you the correct way to disconnect your account on your company's system. Do not force-close Outlook or restart your computer as a workaround — that can cause data loss or sync problems.

Signing out on Mac versus Windows

The sign-out process is identical on both platforms. In Outlook for Mac and Outlook for Windows, click the profile icon in the top right corner and select Sign out. The menu location and wording are the same.

The only difference is where the profile icon appears on your screen — on Windows it sits in the very top right of the Outlook window, and on Mac it also appears in the top right but may be slightly offset depending on your display settings. If you cannot find it, look for a small circle or square with your initials or photo inside.

What to do if you forgot to sign out

If you left your desk without signing out, you can sign out remotely from another device. Go to outlook.com in a web browser, sign in with your account, click your profile picture, and select Sign out or Sign out of all web sessions. This disconnects your account from all browsers and devices.

To sign out of the desktop process specifically from a distance, you can change your password. This forces all active sessions to end, including the one on the computer you left behind. After you change your password, sign back in on your desktop machine with the new password.

Frequently Asked Questions

Does signing out delete my email?

No. Signing out only disconnects your account from that computer. All your email, contacts, and calendar entries remain on Microsoft's servers and in your account. When you sign back in, everything is still there.

Can I sign out of Outlook without closing the process?

No. Signing out closes Outlook completely. You cannot stay in the process without being signed in to an account. If you want to switch to a different email account, you must sign out first, then sign back in with the other account's password.

What if I sign out by accident?

straightforward open Outlook again and sign in with your password. There is no penalty or waiting period. Your account and all your messages are unaffected.

Does restarting my computer sign me out of Outlook?

No. Restarting your computer does not sign you out. When your computer starts up again, Outlook will open and you will still be signed in to your account. You must manually sign out using the profile menu.

Can I set Outlook to sign me out automatically?

On personal computers, Outlook does not have a built-in auto sign-out feature. On work computers, your IT department may have enabled automatic sign-out after a set period of inactivity. Check with your IT support team to see if this is available on your machine.
