What would you do if you are not able to send or receive mails through Outlook? This would be a matter of serious concern for all Outlook users. So, everyone starts looking for methods to solve the issue as soon as they know about Outlook errors. Most of the Outlook errors can be resolved just by restarting your system/Outlook, checking account settings, using scan PST, etc. But there are some errors that require explicit methods to undo them.

In this article, we will be going through some common Outlook errors, their causes, and methods to resolve them. So, in the section below, we have listed some common Outlook errors along with the reason for their occurrence. Also, we introduce a professional Outlook PST repair tool recommended by experts.

Common Outlook Errors

  1. Outlook Connection Error – Invalid Name of the Target Machine
  2. You must have encountered Outlook Connection Error once in a while. The reason behind this error usually is an invalid entry of the target machine or an incorrect IP address.

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

    Sometimes errors in Outlook prompt with a specific error code. These error codes have an alphanumeric structure which makes users wondering what exactly went wrong.

    Error messages with codes like 0x80070002, 0x8004210B, and 0x800CCC0F are general for Outlook users. We will discuss these three errors in a more detailed manner.

  3. Error 0x80070002
  4. The main reason behind this error is PST corruption. Since we all know that PST is a data file in which Outlook holds all the mailbox items. If your PST associated with your current Outlook profile gets corrupted, you will most likely face error 0x80070002.

    You can rectify your PST corruption issue either using a manual approach or with the help of a third-party software.

  5. Sending Reported Error – 0x8004210B
  6. A Sending Reported Error (0x8004210B) indicates that the remote server that keeps your Outlook emails is unable to fetch instructions quickly. Users face this error while sending or receiving emails. Other reasons that could lead us to this error are: Invalid entries in the Windows registry, Virus Intrusion, Installation errors, etc.

  7. Error 0x800CCC0F
  8. This error occurs when users try to send/receive emails in Outlook. Some of the root causes behind the error are: Internet Connectivity issues, Firewall blocking the connectivity between Outlook and server, PST corruption issues, etc.

  9. Time-Out Error 0x800ccc19
  10. One of the prominent reasons behind this error is invalid SMTP or POP port value. If you have configured the Outgoing (SMTP) server to work without encryption but provided an invalid value for the port number, the timeout error can happen. Other reasons might include misconfigured system file, firewall settings, Internet connectivity issues, etc.

  11. Access Denied – Outlook Data File
  12. Sometimes Outlook is not able to access the data files; this usually happens when you attempt to open the Outlook data file on a different system. Fortunately, you can rectify this issue with the help of some common manual methods like changing the location of the Outlook data file, launching Outlook with administrative privileges, etc.

  13. Unable to Access Outlook Attachments
  14. Attachments errors are common for Outlook users; Outlook usually blocks attachments from unknown senders for the sake of data security. Attachments can be blocked also because of unrecognized file formats, suspicious attachments, corrupt files, etc.

    You can sort out this issue with the help of some common configurational changes.

  15. Error – Outlook.pst is not a Personal Folders File
  16. This error tends to pop-out when you attempt to launch Outlook. The main reason, however, is the corruption of PST. Outlook simply denies the existence of PST because the file is corrupt and cannot be accessed anymore.

  17. POP Server Timeout Error – 0x8004210a
  18. This error mainly occurs because of the wrong timeout settings of the POP server. To be more precise, Outlook uses a pre-defined time span to send/receive email messages, and when you try to send/receive a large number of emails, Outlook throws a Server Timeout Error 0x8004210a. The primary method to resolve this error is to change the timeout settings or temporarily uninstall the antivirus program you are currently using on your system.

  19. Cyclic Redundancy Check Error in Outlook
  20. This kind of error usually indicates that there are some issues on the disk where your Outlook PST is located. This has nothing to do with the email client rather, it specifies bugs on your hard drive. Some common troubleshooting techniques can be used in order to fix your local hard drives.

Common Fixes for Outlook Bugs and Errors

  1. Check Internet Connectivity
  2. A disturbed internet connection can lead to errors like 0x800CCC0F, 0x8004210a and 0x8004210a. Avoid low bandwidth Internet connection and use a reliable Internet connection with reasonable download/upload speed.

  3. Avoid Accessing Suspicious Emails
  4. Emails or email attachments from unknown senders can be potential threats to your system. For instance, a virus-infected email can crash your Outlook program and corrupt several important system files. You can use a reliable antivirus program to block external threats, or you can simply delete suspicious emails in the first place. Also, take care to use the latest version of the operating system with the necessary security features.

  5. Check the Antivirus Settings
  6. Check your antivirus for email scanning settings. Some configurational changes or default features of antivirus can restrict the connectivity of your Outlook to the server. You can either manually disable such features from your antivirus program or temporarily uninstall the antivirus from your machine. Also, don’t hesitate to contact your antivirus provider if you need any help.

  7. Reinstall Outlook
  8. Reinstalling your Outlook client can fix installation errors and common software failures. In case of Outlook crash, re-installing the application is the most recommended method to fix the issue.

  9. Change the Server Time-Out Settings

    You can manually increase the time span for establishing connectivity of your Outlook program to the server. Typically, a less Server Time-Out period can throw various errors. Follow the instruction given below to change your Server Time-Out settings.

    • Launch Outlook and navigate through Files >> Info.
    • Click Account Settings >> Account Settings.
    • Select the target POP3 account and click the Change button.
    • In the Change Account window, click More Settings.
    • Go to the Advanced tab and increase the Server Timeout period.
  10. Clear or Move Email from Outlook Folder
  11. Data overloading can be a reason for Outlook malfunction. Clear unnecessary files from Outbox and Trash folder to optimize the performance of your Outlook application. Also, try to use necessary Outlook features and features to enhance the performance of Outlook as well as Windows.

  12. Rectify PST Corruption via Third-party tools
