Although MS Outlook supports many functions, its sole purpose is to send or receive communication emails. MS Outlook and Outlook Express are email clients widely used in the modern world to establish an official connection. There are also some problems. If something doesn’t work, Microsoft Outlook and Outlook Express will display an error. A common mistake is “send or receive error”, which worries users. So let’s take a look at ways to troubleshoot send or receive errors.

Disable or uninstall your antivirus program

Visit the antivirus manufacturer’s website for more suggestions, or turn off your antivirus software. Disable the router firewall. If you find that Outlook works fine after disabling your antivirus software, we strongly recommend that you uninstall it and then reinstall it using the erase tool.

Check Outlook settings

This Microsoft Outlook error usually occurs when there is an authentication issue when sending messages. Check your email client settings to see if username and password authentication is enabled on the outgoing email server. This is important when using our SMTP server. If you are using MS Outlook Express, you will find this option here in the menu: Tools -> Accounts -> Accounts -> Mail tab -> Properties -> Server tab -> My server requires authentication.
