Have you ever encountered an error message while using Microsoft Outlook? Often, error messages cause Outlook to crash or stop responding. And sometimes, mistakes can lead to corruption if not resolved in time. In this article, we will discuss five common error messages. Also, we will learn to correct those mistakes without power.
Microsoft Outlook is a world-famous email client application that is used worldwide to send and receive email messages. Besides being an email app, it has flexible features like creating meetings, appointments, tasks, notes, and much more. However, problems with Microsoft Outlook occur inevitably not only due to performance failures but also due to software malfunctions.
General Outlook Error Messages
Whenever there is any problem in Microsoft Outlook, you may encounter different error messages. Below are the top 5 error messages:
1 – Unable to open your default email folders
Suppose you start Microsoft Outlook, and you come across an unexpected error message that reads,
“You can’t open your email folders. An unexpected error occurred. MAPI could not load information service msncon.dll. Make sure the application is properly installed and configured.”
The msncon.dll error refers to the problem with the Outlook Hotmail Connector. So this error message is associated with the Outlook Hotmail Connector. A freeware tool provided by Microsoft to access and manage MSN, Live, and Hotmail accounts using Microsoft Outlook. There are two cases where you can find this error:
The Outlook connector is no longer installed.
It looks like the Outlook Hotmail Connector is no longer installed on your system, but you still have an MSN / Hotmail account set up with Microsoft Outlook. You have two options here:
It’s about reinstalling the Outlook Hotmail Connector again;
Or, delete the MSN / Hotmail account from your mail profile if you no longer want to use it.
But if the latest version of Outlook Connector is already installed on your system and you still get this error message, follow these simple steps:
- First, allow the installation inside.
- Now install the Outlook Hotmail Connector on your system. Then delete the MSN / Hotmail account from the Outlook client.
- Restart Microsoft Outlook and enter the MSN / Hotmail account and use the Hotmail Connector menu.
- When the account is successfully created, set up Office installation.
- When you’re done, re-create your post profile.
2 – Connecting to Microsoft Exchange Server is not available
Outlook errors are always difficult to resolve, especially this one. The error message is readable,
“Communication with Microsoft Exchange Server is not available. Outlook must be connected to the Internet or connected to complete this action.”
Being one of the most common Outlook error messages, you may encounter this error many times. The most likely reasons for this error are:
No data connection
Probably no data connection right now. It would help if you therefore started by using the Telnet protocol to check your SMTP connection. If not, you should take the help of this guide published on Microsoft TechNet: Check SMTP via Telnet.
Outlook Data Files Locked
Outlook data files, i.e., PST and OST files, maybe locked by mistake, and you are completely unaware of them. Or maybe Outlook data files are set to read-only mode. You should check the permissions for these files better and make sure none are set to read-only mode.
Interruption of Third Party Applications
Many third-party programs can disrupt Outlook while it is connected to Exchange Server. If this is the real cause, you should better start Outlook in safe mode.
3 Outlook is unable to connect to the proxy server
This error message occurs when an Outlook client tries to connect to a server using an RPC (Remote Procedure Call) connection or an HTTPS (Hypertext Transfer Protocol Secure) connection. The error message is readable,
“There is a problem with the server’s security certificate. The security certificate does not come from the verification manager. Outlook cannot connect to the hosting server.”
There are various reasons for this Microsoft Outlook error, such as
- Certificate Authority is required to connect to the server.
- You may have forgotten to rely on the certificate root manager.
- The certificate appears to be invalid or canceled.
- The site name does not match the certificate.
- Perhaps an add-on or a third-party browser is causing this error.
- To resolve this Outlook error, there are several things you can try:
Check the certificate
- First, you need to check the certificate and then contact your system administrator to resolve the issue. Follow these simple steps:
- First, connect to an RPC server or secure server in Microsoft Internet Explorer. Type https://www.server_name.com/rpc in the address bar then hit Enter.
- Now double-click the lock icon in the lower right corner of the web browser.
- Click the Details tab, and check details for these two fields:
- This field indicates the date the certificate is valid until then.
- Make sure this field must match the site name.
Install a trusted root certificate
You need to follow these steps to install a trusted root certificate:
- In the Certificate dialog box, click Install Certificate> Next.
- Now check the Location of the entire certificate in the next store box. Then click Browse.
- Click Trust Certificate Authorities, and then click OK.
- Now click Next> Finish> OK.
Disable third-party extensions
Before you can disable any third-party login, you must start Outlook in safe mode.
- Just press Win + R to use Command Prompt.
- Type Outlook.exe / safe in the edit box then hit Enter.
If Outlook starts in safe mode without a problem, this means that the real problem is associated with third-party extensions. So here, you need to look at other COM COM external companies and disable them.
- First, launch Microsoft Outlook. Then, in the taskbar, click the File tab> Options> Insert.
- Click COM add-ons in the control box, then click Go.
- Clear the checkboxes shown next to the third-party add-ons you want to disable.
- Now restart Microsoft Outlook.
Important Note: Remember, Outlook uses Internet Explorer settings for HTTPS applications. If a third-party browser extension is causing this problem, you should try disabling it in Internet Explorer.
4 – Outlook Send Receive Error 0x800ccc13
Usually, most Outlook errors occur when sending and receiving email messages. Outlook 0x800CCC13 error is one of the most common problems faced by users. It reads as follows,
“Reporting error reported (0x800CCC13): Unable to connect to network. Verify your network connection or modem.”
This is the most common Outlook error in any Microsoft Outlook application, whether 2016, 2013, 2010, 2007, 2003, etc. I recently upgraded to Windows 10 with more opportunities to discover this common Outlook error.
To resolve Outlook 0x800CCC13 error, be sure.
- You are using Windows 10 Enterprise and Pro 1511 (Build 10586) or another higher version.
- And with Windows Home, you must have type 10 (10240) or higher.
But if you still get this Outlook Send Receive error, maybe the program files are corrupted, and you need to repair them. You can use Windows System File Checker to repair corrupted files.
- First, close Microsoft Outlook.
- Now right-click on Start in Windows and select Command Prompt (Admin).
Note: If you do not see the option, you can select Windows PowerShell (Admin).
- Type sfc / scannow in Prompt command. This process can take up to 20 minutes to scan a standard hard disk. Please wait until the process is complete. When the process is complete, restart your computer and open Microsoft Outlook.
5 – Cannot start Microsoft Outlook
Microsoft Outlook often encounters unexpected errors that can lead to serious problems. This Outlook error is widely read,
“Cannot start Microsoft Outlook. Unable to open Outlook window. Folder cannot be opened. Operation failed.”
There are many reasons related to this standard Outlook error. Perhaps the file that saves the Navigation Pane settings, called profilename.xml, is corrupted. And that’s why you get this error message. You can find this file in the following folder:
Note: If you see the XML file size is 0 KB, you are a strong indicator of corruption.
To solve this problem, follow these simple steps:
- Just press Win + R to use Command Prompt.
- Now type Outlook.exe / resetnavpane in the edit box, then hit Enter.
If the above strategy does not fix the problem, you should follow the workaround given below:
- Make sure Microsoft Outlook does not work in compatibility mode.
- Keep in mind that Microsoft Outlook may not start when you use an older profile of any older version of Outlook. So make sure you create a new Outlook profile and use it.
- Installing and reinstalling Microsoft Outlook more than once may cause this error if done incorrectly.
- And most importantly, if you have a corrupt Outlook data file, you may encounter this error. You can use the scanpst utility to edit a PST file.
