Top 10 Outlook Errors and Ways to Fix Them

If you can’t send or get emails via Outlook, what would you do? All Outlook users would be seriously concerned about this. So, as soon as they know about Outlook errors, everybody starts looking for methods to resolve the problem. Most Outlook errors can only be solved if you restart the system/Outlook, check the settings of the account, PST scan, etc. However, certain errors require explicit methods of reversing them.

This blog post will experience some common Outlook errors, their causes, and ways of resolving them. Therefore, some common Outlook mistakes were listed in the following section with the reason why they occur.

Common Outlook Errors:

  • Outlook Connection Error – Invalid Name of the Target Machine:

Outlook Connection Error must be found once in a while. The reason for that error is usually the incorrect entry or IP address of the target machine.

Outlook Error Codes: 0x80070002, 0x8004210B, and 0x800CCC0F

Sometimes errors with a certain error code in Outlook prompt. These error codes have an alphanumeric structure that makes users question what was wrong exactly.

Outlook users have general error messages such as 0x80070002, 0x8004210B and 0x800CCC0F. These three mistakes will be discussed in greater detail.

  • Error 0x80070002

PST corruption is the primary reason for this error. Because we all know that PST is a data file that contains all the mailbox items in Outlook. You will probably face an error of 0x80070002 if your PST with your current Outlook profile gets corrupt.

  • Sending Reported Error – 0x8004210B

A reported error sending (0x8004210B) indicates that your Outlook emails are not quickly receivable via remote servers. This error is experienced by users when emails are sent or received. Another reason for this mistake is Windows registry invalid entries, Virus Intrusion, Installation errors, etc.

  • Error 0x800CCC0F

This error occurs when users attempt to send/receive Outlook emails. Some causes behind the error are Internet connectivity problems, Firewall blocking Outlook-Server connectivity, PST corruption problems, etc.

  • Time-Out Error 0x800ccc19

The invalid SMTP or POP port value is one of the leading reasons for this error. The timeout error may be caused if the outgoing (SMTP) server has been configured to work without encryption but the port number has been given an invalid value. False system files, firewall settings, connectivity issues, etc. could be further reasoned.

  • Access Denied – Outlook Data File

Sometimes Outlook can’t access data files, normally when you try to open the data file in Outlook on a different system. Fortunately, this problem may be rectified using certain common manual methods such as changing the Outlook database location, launching Outlook with administrative privileges, etc.

  • Unable to Access Outlook Attachments

Attachment errors are common among Outlook users; for the sake of data protection Outlook usually blocks attachments from unknown senders. Attachments can also be blocked due to unknown file formats, suspicious attachments, corrupted files, etc.

  • Error – Outlook.pst is not a Personal Folders File

When you attempt to launch Outlook, this error tends to appear. However, the primary reason is PST corruption. Outlook simply denies PST, as the file is corrupt and no longer accessible.

  • POP Server Timeout Error – 0x8004210a

Most of the timeout settings of the POP server cause this error. To be precise, Outlook sends email messages over a predefined length and Outlook is throwing a Server Timeout Error 0x8004210a when trying to e-mail/receive a large number of emails. The main method for resolving this error is to change the timeout configuration or to temporarily uninstall your current antivirus application.

  • Cyclic Redundancy Check Error in Outlook

This kind of error usually indicates that the disc where your Outlook PST is located has certain problems. It’s not the e-mail client, it specifies bugs on your hard disc. Some common troubleshooting methods may be used to fix your local hard discs.
