After changing the internet speed outlook mail not sending mails

That's frustrating!

It's possible that the change in internet speed is causing issues with Outlook's ability to send emails. Here are some troubleshooting steps you can try to resolve the issue:

  1. Check your internet connection: Ensure that your internet connection is stable and working properly. You can try restarting your router or modem to see if that resolves the issue.
  2. Check Outlook's connection settings: Make sure that Outlook is configured to use the correct internet connection settings. Go to File > Account Settings > Internet Calendars, and ensure that the correct internet connection is selected.
  3. Check your DNS settings: Sometimes, changes in internet speed can affect DNS (Domain Name System) settings. Try flushing your DNS cache by pressing the Windows key + R, typing "cmd" and pressing Enter. Then, type "ipconfig /flushdns" and press Enter.
  4. Check Outlook's server settings: Ensure that Outlook is configured to use the correct server settings. Go to File > Account Settings > Account, and check the server settings for your email account. Make sure that the server settings are correct and match your email provider's settings.
  5. Try sending a test email: Try sending a test email to yourself or a friend to see if the issue is specific to a particular email account or if it's a general issue with Outlook.
  6. Check for Outlook updates: Ensure that Outlook is up to date by checking for updates in the Microsoft Store or by downloading the latest version from the Microsoft website.
  7. Try restarting Outlook: Sometimes, simply restarting Outlook can resolve the issue. Try closing and reopening Outlook to see if that resolves the problem.
  8. Check for firewall or antivirus software issues: Firewalls or antivirus software can sometimes interfere with Outlook's ability to send emails. Try temporarily disabling your firewall or antivirus software to see if that resolves the issue.
  9. Check your email provider's status: If you're using a third-party email provider, check their status page to see if there are any known issues or outages that might be affecting your ability to send emails.
  10. Contact your email provider or IT support: If none of the above steps resolve the issue, you may want to contact your email provider or IT support for further assistance.

I hope these steps help you resolve the issue with Outlook not sending emails after changing your internet speed!
