Outlook. Not receiving or sending emails

This still hasn't worked and I'm getting nowhere trying to follow your automated instructions. Please call me on XXXXXXXXXXX. Colin

Hi Patti,  Thank you for posting in Microsoft Community.

If you are unable to send or receive emails in Outlook, there are several troubleshooting steps you can take:

1. Check if Outlook is disconnected or in offline mode. If so, toggle between offline and online mode by selecting the "Work Offline" option in the "Send/Receive" tab.
2. Ensure that you are connected to the internet. Open a browser and try accessing websites like microsoft.com or bing.com to verify your internet connection.
3. Check if your email messages contain large attachments. Some email providers have size limitations for attachments. Remove large attachments or replace them with smaller files.
4. Verify if you have recently changed your email account password. If so, update the password in Outlook by going to "File" > "Account Settings" > "Account Settings" and entering the new password.
5. Contact the help desk of your antivirus software if you suspect that it is blocking your email functionality.
6. If the above steps don't resolve the issue, you can try repairing your Outlook program or creating a new Outlook profile.
7. In case you are using Outlook for Mac, there are specific troubleshooting steps mentioned in.

Please note that these are general troubleshooting steps, and the specific solution may vary depending on your email provider and configuration.
