Answer 1

Hello Ken Hrycik

Thank you for reaching out to Microsoft Q&A Forum. I understand how frustrating it is when Outlook suddenly stops sending emails after connecting to a new Wi‑Fi.

I can see there’s a Q&A Assist reply under your post. To avoid repeating it, could you tell me if you’ve tried those steps yet, and what happens when you try?

In the meantime, please try the following steps:

1. Test on Outlook on the web

• Please sign in at Outlook on the web and try sending an email there.
• If it fails on the web, this points to an account-level restriction.
• If it works on the web but not in the app, the issue is local to the app/device.

2. Restart Outlook in safe mode

• Close Classic Outlook app completely
• Press Windows + R, type outlook.exe /safe > press Enter
• Try sending a test email in Safe Mode

3. Check Work Offline mode

• In Outlook, go to Send/Receive tab at the top > make sure Work Offline is not enabled

 

4. Check the Outbox folder in app

• If messages are stuck in Outbox, close Outlook, reopen it, then try sending again.
• If it still won’t send, move the message to Drafts, open it from Drafts then Send again

5. Firewall/antivirus check

Temporarily disable firewall or antivirus software to see if they are blocking outgoing mail.

For more details, please refer to this official guide: I can't send or receive messages in Outlook - Microsoft Support

Thank you for your time and understanding. Feel free to let me know how it goes.

If you're unable to send emails in Outlook after connecting to a new Wi-Fi network, it may be related to a metered connection or other issues. Here are some steps you can take to resolve the problem:

1. Check for Metered Connection Warning: If Outlook detects that you're on a metered connection, it may restrict certain functionalities. Look for a warning message in Outlook that indicates this.
2. Update Outlook: Ensure that your Outlook is up to date. You can check for updates by opening any Office application, selecting File, then Office Account, and looking for updates under Office Updates. If your version is earlier than 2008, select Update Options and then Update Now.
3. Repair Office: You can try repairing your Office installation. This can often resolve issues that prevent sending emails. Instructions for repairing Office can be found on the Microsoft support site.
4. Check Third-party Applications: Sometimes, third-party applications that access the MAPISVC.inf file can interfere with Outlook. You can use Process Monitor to identify any processes that might be causing issues and stop them.
5. Registry Fixes: If you're comfortable with it, you can check the registry for issues related to permissions or specific keys that might be causing problems. However, be cautious and back up the registry before making changes.

If these steps do not resolve the issue, you may want to check for service issues with Microsoft 365 or consult with your IT administrator if applicable.
