Methods to Troubleshoot and Resolve Outlook Error 0x80040610

Follow the methods discussed below with stepwise instructions to troubleshoot and resolve this issue.

Make sure to follow these methods in the given sequence as we move from the most basic to advanced troubleshooting methods.

Method 1: Check Network Connection

Poor, unstable, or slow network/internet connection on the client or server machine can prevent Outlook from synchronizing the mail items or downloading the emails from your POP3 mail server. As a result, it may lead to error 0x80040610.

To avoid this, make sure to check and test your internet/network connection and server status. First, open a web browser and visit any website.

If you see a network connection error or no internet, then follow these steps:

1. Restart router/modem.
2. If using a wired ethernet cable, try disconnecting and reconnecting. Make sure the cable is not faulty.
3. Check the DNS. If you are using custom DNS, such as AdGuard, make sure to change it to Google DNS or any other public DNS.
4. On the web browser, try to open the mail login page and log in to your email account. If you can’t log in, probably the password has expired. Contact your administrator in such a case. 
5. If the webmail site does not load, the mail server could be down. You can wait and try again later or connect with the administrator for immediate help.

Method 2: Disable Conflicting Add-ins

If the internet is working fine and the server is online, you can try to check if any faulty or incompatible add-ins could be causing the 0x80040610 error.

The steps to finding and disabling faulty add-ins are as follows:

• Press Windows + R, type Outlook.exe /safe, and click OK. This opens Outlook in safe mode. 
• Then go to File > Options.
• Click Add-ins in the left-hand sidebar and then click the Go button.

• Uncheck all the add-ins and click OK.  Doing this will disable the add-ins.
• Restart Outlook normally and check if the error is resolved.

If the error does not appear and you can send/receive new emails, then activate one add-in at a time and restart Outlook to check which add-in was causing the error. Once found, remove it from the Outlook.

Method 3: Disable Antivirus Software Temporarily

Sometimes, conflicts with antivirus software or firewall can interfere with Outlook and trigger error 0x80040610.

To ensure whether the antivirus software is the culprit, you can disable it temporarily.

Then observe Outlook for the error. If the error is resolved, you can perform any of the below steps to permanently fix the error:

1. Permanently disable the antivirus
2. Add exceptions in the antivirus and firewall
3. Get Outlook-aware and Office-compatible antivirus software to avoid these conflicts
