If Outlook email is not working today, check Microsoft’s service-health page first, then test the same account in Outlook on the web or on another device. I can’t verify live outage conditions here, so the quickest way to tell whether Microsoft or your setup is responsible is to compare the service status with what happens across devices.
First, find out whether Outlook is down
Start at Microsoft 365 service health for public updates about Microsoft 365 services. If you have a work or school account and are a Microsoft 365 administrator, open the Microsoft 365 admin center and select Health > Service health for tenant-specific details. A notice affecting Exchange Online or Outlook is a strong sign that the problem is on Microsoft’s side. Service notices can describe only certain regions or features, so read the incident details rather than assuming every Outlook user is affected.
Next, compare how the account behaves in different places. For a personal Microsoft account, try Outlook.com; for a work or school account, try Outlook on the web. If webmail works but the desktop app does not, focus on the app or device. If the same account fails on several devices and networks, a service disruption, account restriction, or sign-in problem is more plausible.
Downdetector and social-media posts can show that other people are reporting trouble, but they are not Microsoft’s confirmation of an outage. A sudden burst of reports is a clue, not proof. During a confirmed incident, repeated restarts, password changes, and reinstallations usually do not fix the underlying service problem. Check for updates and use another available route to your email while Microsoft works on the issue.
Identify which Outlook service is affected
“Outlook” can mean the Outlook app, Outlook.com, or the mail service behind a work or school mailbox. The distinction matters because each has a different support route. Outlook.com is commonly used with personal Microsoft accounts; organizations often use Exchange Online, but some workplaces connect Outlook to other mail systems. A company may also apply its own sign-in rules or service restrictions.
Notice what is failing. A blank or inaccessible inbox points to a different problem than messages stuck in the Outbox, a password prompt that keeps returning, or missing calendar updates. Check whether you can sign in, open folders, search old messages, and send a short test email to an address you control. Record any error message and when it appeared; those details help support staff distinguish a login issue from a sending or syncing fault.
It is also possible for email to work while another feature is impaired. Calendar, contacts, shared mailboxes, search, and attachments may have separate symptoms. If only one function fails, check the service notice for that specific feature and avoid changing unrelated settings.
Quick checks before changing settings
Rule out basic connection and device issues before removing an account or rebuilding a profile. Open another trusted website, switch between Wi-Fi and mobile data if practical, and temporarily disconnect a VPN only if your organization permits it. A captive hotel or public Wi-Fi login page can make a device look connected while blocking email traffic. If other online services are also failing, troubleshoot the network first.
- Check that the device has the correct date and time; incorrect settings can interfere with secure sign-in.
- Close and reopen Outlook, then restart the device if the app remains frozen.
- Check available storage. A nearly full phone or computer can prevent an app from updating or saving data properly.
- Install pending Outlook, browser, and operating-system updates from their official update tools.
- Look for an error banner, an Outbox message, or an Offline indicator instead of repeatedly pressing Send.
Try one change at a time and retest. For example, if Outlook works after switching networks, the original network, VPN, or firewall is a more likely cause than the mailbox itself. Avoid deleting messages or removing an account as an early experiment: some account types may keep local-only data that is not stored on the server.
Fix Outlook in a browser, on Windows, or on Mac
If Outlook on the web fails in one browser, open it in a private or InPrivate window. If that works, a browser extension, stale site data, or a stored sign-in session may be involved. Update the browser, disable extensions temporarily, or clear site data for Outlook and Microsoft sign-in pages, then sign in again. Clearing all browser data can sign you out of other sites, so start with the narrowest option available.
In classic Outlook for Windows, check whether Send/Receive > Work Offline is enabled. If it is, select it to reconnect, then try sending or receiving again. The classic app may also show connection information in its status bar. If Outlook is still misbehaving, update Microsoft 365 from File > Office Account > Update Options > Update Now, where those options are available. New Outlook for Windows has a different interface, so classic Outlook menu instructions may not match it.
On a Mac, install Office updates through Help > Check for Updates if Microsoft AutoUpdate is available. Quit and reopen Outlook, and check that macOS is online. Menu labels and features can vary with the Outlook version. On either platform, do not remove a work account or create a new profile unless you understand how the mailbox is configured or your IT team recommends it; those steps can affect locally stored mail, add-ins, or organization-managed settings.
When messages will not send or arrive
If a message is stuck in the Outbox, open it and check the recipient address, attachment size, and any warning displayed by Outlook. A large attachment may exceed a limit set by the mail provider or organization. Use a cloud link when your workplace permits it, or send a smaller file. Check that the message is not still being edited in a separate window and that Outlook is connected before trying again.
If you can send but not receive, inspect Junk Email, Other, Archive, and any focused or filtered inbox view. Search for a recent message by sender or subject. A full mailbox can stop new mail from arriving, depending on the account and provider. For a work account, a rule, quarantine policy, forwarding setting, or administrator restriction may also affect delivery. Ask the sender whether they received a bounce or nondelivery report; that notice often identifies the rejected address or policy.
If Outlook says a message was sent but the recipient cannot find it, check Sent Items and confirm the exact address. Ask the recipient to check junk mail and organizational quarantine. Delivery can be delayed by the recipient’s mail system even when Outlook has accepted the message. Avoid sending the same important email repeatedly without checking first, since duplicate messages can create confusion.
Account access, security, and work accounts
A repeated password prompt does not always mean the password is wrong. The saved sign-in token may have expired, a multifactor authentication request may be waiting, or an organization may require a new sign-in after changing security policies. Sign in through the official Outlook website and complete any Microsoft account verification prompt there. Do not share a verification code with someone who contacts you unexpectedly.
If the website reports that the account is locked, blocked, or needs verification, follow the recovery steps shown by Microsoft rather than repeatedly guessing passwords. For a work or school mailbox, contact your organization’s IT support if the account is disabled, a licensing message appears, or an administrator-managed sign-in requirement prevents access. Personal-account recovery and workplace account administration are separate processes; a company help desk cannot necessarily restore a personal Microsoft account.
Be cautious of messages or search ads claiming to fix an Outlook outage by asking for your password, remote access, or payment. Use Microsoft’s official status and support pages, and reach workplace support through a known company channel. A genuine outage does not require you to disclose a password to a caller or install an unfamiliar repair tool.
Ways to keep working while Outlook is unavailable
If webmail works, use it temporarily from a trusted device and network. If only the app is affected, Outlook on the web can help you read and send mail while you troubleshoot. For a work account, follow your organization’s rules about public computers, sensitive attachments, and personal devices. Sign out when finished, especially on a shared machine.
If no route is available, save a draft locally in a secure place and note the people you need to contact. Do not assume a message in the Outbox has reached its recipient. For urgent work, use an approved alternative channel such as your organization’s phone or messaging system. When the service recovers, check the Outbox and Sent Items before resending drafts, and verify that delayed messages went to the intended addresses.
Keep the recovery proportionate to the evidence. A broad Microsoft service notice calls for waiting and monitoring updates; a problem limited to one browser calls for browser troubleshooting; a failure limited to a managed work account calls for IT support. This approach is faster and reduces the risk of deleting useful local data or weakening account security.
Frequently Asked Questions
Is Outlook down today? I can’t confirm live service status from here. Check Microsoft’s public service-health page and, for a work or school account, ask an administrator to check Health > Service health in the Microsoft 365 admin center. Test webmail and another device to see whether the issue is widespread or local.
Why is Outlook not receiving emails but still sending them? Check Junk Email, other inbox tabs, filters, mailbox capacity, and any delivery rules. A sender’s bounce notice can reveal a rejected address or policy. For a work account, ask IT to check quarantine or mail-flow restrictions if ordinary inbox checks do not explain the missing message.
Why does Outlook keep asking for my password? A stale sign-in session, pending multifactor prompt, changed password, or organization security requirement can trigger repeated prompts. Try signing in at the official Outlook website first. If a work account remains blocked or loops back to sign-in, contact your IT administrator.
Will reinstalling Outlook fix an outage? No. Reinstalling the app cannot repair a Microsoft service outage, and it may not help if the problem is the network or account. First compare the service status and test webmail. Consider reinstalling only when evidence points to a damaged app installation and safer update or restart steps have failed.
How can I tell whether an email actually sent? Look for it in Sent Items and check whether Outlook still shows it in the Outbox. If the recipient does not see it, confirm the address and ask them to check junk mail or quarantine. For an important message, verify delivery through a separate channel before sending another copy.
