Windows Mail App Not Working

In today’s fast-paced business world, email communication is the backbone of daily operations.

When your office mail app suddenly throws Mail not working error messages and stops working, it can be a major hindrance to productivity.

But fear not, for this article will guide you through the troubleshooting process to get your office mail app back up and running smoothly.

Mail Not Working

Identify the Mail App Not Working Error :

The first step in troubleshooting is to understand the error message you’re encountering. Different error messages indicate different issues. Some common error messages include:

“Unable to connect to server”
“Authentication failed”
“Mailbox full”
“Email not sent”

Check Your Internet Connection:

A stable internet connection is vital for your office mail app to function correctly. Ensure you are connected to a reliable network and try restarting your router if necessary.

Verify Server Settings:

Incorrect server settings can lead to connection errors. Double-check your incoming and outgoing server settings, including server names, ports, and security protocols.

Make sure they match the settings provided by your email service provider or IT department.

Review Account Credentials:

An “Authentication failed” error often indicates incorrect login credentials. Verify your username and password and be mindful of case sensitivity.

If you’ve recently changed your password, update it in the app’s settings.

Clear Cache and Data:

On mobile devices, clearing the cache and data of the mail app can resolve various issues. Go to your device’s settings, find the mail app, and clear its cache and data.

Note that this might delete locally stored emails, so ensure you have backups if needed.

Check Email Storage Quota:

If you’re receiving a “Mailbox full” error, your email storage might be reaching its limit. Delete unnecessary emails or attachments and consider archiving older messages to free up space.

Update or Reinstall the App:

Outdated or corrupted app versions can cause problems. Ensure your office mail app is up to date. If the issues persist, consider uninstalling and reinstalling the app to start fresh.

Scan for Malware and Viruses:

Malware or viruses on your device can interfere with app functionality. Run a thorough scan using reputable antivirus software to eliminate potential threats.

Check Email Service Status:

Sometimes, the issue may not be on your end but with the email service provider. Check their status page or contact their support for information on any ongoing outages or server issues.

Contact IT Support:

If none of the above steps resolve the problem, don’t hesitate to contact your organization’s IT support team. They can provide specific assistance tailored to your office mail setup.


When your office mail app encounters errors and stops working, it can disrupt your workflow. However, with these troubleshooting steps, you can often diagnose and resolve the issues yourself.

Remember to stay patient and persistent, and don’t hesitate to seek professional help if needed. Keeping your email system in top shape is crucial for maintaining efficient communication in the workplace.
