Outlook is a widely used email client, but users often face issues such as Outlook Error 500, which displays the message “Something went wrong.”
This error can prevent access to emails, disrupt workflows, and create frustration. Understanding the root cause of this issue and applying the correct troubleshooting steps can help users resolve it effectively. This blog post will delve into the details of Outlook Error 500, its variations, and the best solutions to fix it.
What is Outlook Error 500?
Outlook Error 500 is a server-side issue that typically occurs when a user tries to sign in to their Outlook account, access their mailbox, or send emails. The error message often reads, “Something went wrong,” making it difficult to determine the exact cause. This error can affect Outlook on the web (OWA), Microsoft 365 accounts, and desktop applications connected to Exchange servers.
Users may also encounter variations of this error, such as Outlook Error 500 Undefined or Outlook Unhandled Rejection Error 500. Each variation points to a slightly different underlying cause but generally relates to account connectivity, authentication, or server-side issues.
Is ‘ServerError 500’ a Microsoft Issue?
Yes, in most cases, Outlook Error 500 is a Microsoft issue, primarily caused by server-side failures, maintenance activities, or misconfigurations in Exchange Online. Microsoft acknowledges this error and often releases patches to fix the problem.
Users can check Microsoft’s service status page at portal.office.com/servicestatus to determine if the issue is widespread.
Common Causes of Outlook Error 500
Server-Side Issues: Microsoft’s servers may experience temporary outages or maintenance, leading to login failures.
Syncing Delays in Connected Accounts: If there are delays in syncing Outlook with connected accounts such as Gmail or Yahoo, the error may occur.
Incorrect Mailbox Configurations: Exchange Admin settings, including disabled email connectivity features, can trigger this error.
Authentication Problems: If Outlook fails to authenticate a user’s credentials, it may generate this error.
Corrupt Browser Cache or Cookies: Cached login data in browsers like Chrome, Edge, or Firefox can interfere with Outlook’s web login.
Third-Party App Conflicts: External applications linked to Outlook, such as third-party email clients, can create conflicts that lead to authentication errors.
Outlook Error 500: Something Went Wrong While Sending Email
Some users report encountering Outlook Error 500 specifically when sending emails. This issue may be related to:
- SMTP authentication failures
- Disabled email sending permissions in Exchange Admin settings
- Email size limitations imposed by the server
- A temporary block due to suspicious activity on the account
To resolve this, users should verify their SMTP settings, ensure email connectivity is enabled in Exchange Admin Center, and check if their account has been restricted due to excessive email sending.
Outlook Error 500 Undefined – What Does It Mean?
The Outlook Error 500 Undefined message usually appears when the system cannot specify the exact cause of the error. This could be due to missing permissions, an expired session, or server misconfigurations. A quick fix for this issue includes signing out of all Microsoft services and logging back in using an incognito window.
Fix Outlook Error 500: Step-by-Step Solutions
1. Check Microsoft Service Status
Before attempting any troubleshooting steps, visit Microsoft’s service status page (portal.office.com/servicestatus) to determine if Outlook services are down. If there’s an outage, waiting for Microsoft to resolve the issue is the best option.
2. Use an Incognito Window in Chrome
If the error is related to browser cache or cookies, trying to log in via an incognito window can help. Open Chrome, press Ctrl + Shift + N, and navigate to Outlook.com. Sign in and check if the error persists.
3. Clear Browser Cache and Cookies
If using an incognito window works, clearing cache and cookies may provide a permanent fix. In Chrome, go to Settings > Privacy and Security > Clear Browsing Data, then select Cookies and Cached Images and click Clear Data.
4. Use the Mail for Windows 10 App
If Outlook Web Access (OWA) is experiencing issues, users can try using the Mail for Windows 10 app as an alternative to access and manage emails.
5. Revoke and Reauthorize Outlook Access in Gmail (For Linked Accounts)
If the error prevents Gmail emails from syncing in Outlook, users should revoke and reauthorize Outlook’s access:
- Go to Google Account Settings (myaccount.google.com)
- Click on Security
- Scroll down to Third-party apps with account access
- Locate Microsoft Outlook and click Remove Access
- Re-add the Gmail account in Outlook and follow the authorization steps
6. Verify Email Connectivity in Exchange Admin Center
For Office 365 users, the error may stem from disabled email connectivity settings. Administrators should:
- Sign in to Exchange Admin Center with an admin account.
- Navigate to Recipients > Mailboxes and select the affected mailbox.
- Click Edit > Mailbox Features and ensure IMAP, POP3, and MAPI are enabled.
- Verify that Outlook on the Web is also enabled.
7. Check Windows Date and Time Settings
Incorrect date and time settings on Windows can cause authentication failures. To fix this:
- Open Settings on Windows
- Go to Time & Language > Date & Time
- Enable Set time automatically
- Restart Outlook and try logging in again
Preventing Outlook Error 500 in the Future
To minimize the risk of encountering Outlook Error 500 in the future:
Keep Outlook updated to the latest version to receive security and performance improvements.
Regularly clear browser cache and cookies if using Outlook Web.
Use an authenticated and authorized connection when linking Gmail or other accounts.
Monitor Microsoft’s service status to check for ongoing issues before troubleshooting extensively.
Ensure Exchange Admin settings allow proper email connectivity for your account.
