Whenever I try to open an email file, specifically when it has been put on a shared drive, I get an error message: “Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client”.
The issue is, I have set Outlook as the default mail client everywhere. I’ve gone into the Outlook settings, and set it there, I’ve changed the default applications setting to Outlook, I’ve reinstalled Office, repaired Office, changed the defaults to something else and back, but I still get this error. I cannot for the life of me figure out what the problem is.
Microsoft Outlook is one of the most popular email clients used by individuals and businesses around the world. However, like any other software, it is not immune to errors and issues. One of the most common errors that Outlook users encounter is the “Current Mail Client Cannot Fulfill the Messaging Request” error. This error message can be frustrating, especially when you have set Outlook as your default mail client. In this blog post, we will discuss the possible causes of this error and provide solutions to fix it.
Possible Causes of the Error
Before we delve into the solutions, let us first understand the possible causes of the “Current Mail Client Cannot Fulfill the Messaging Request” error. Here are some of the most common reasons why this error occurs:
1. Corrupted Outlook Profile
One of the most common causes of this error is a corrupted Outlook profile. If your Outlook profile is corrupted, it can cause issues when trying to open emails or access other Outlook features. You may need to recreate your Outlook profile to fix this issue.
2. Incorrect Default Mail Client Settings
Another possible cause of the error is incorrect default mail client settings. Even if you have set Outlook as your default mail client, there may be other applications that are interfering with the settings. This can cause conflicts and prevent Outlook from fulfilling the messaging request.
3. Damaged Outlook Installation
A damaged Outlook installation can also cause this error. If some of the Outlook files are corrupted or missing, it can prevent Outlook from functioning properly. You may need to repair or reinstall Outlook to fix this issue.
4. Antivirus or Firewall Settings
Sometimes, antivirus or firewall settings can interfere with Outlook and cause this error. If your antivirus or firewall is blocking Outlook from accessing certain files or features, it can prevent Outlook from fulfilling the messaging request.
Solutions to Fix the Error
Now that we know the possible causes of the “Current Mail Client Cannot Fulfill the Messaging Request” error, let us discuss the solutions to fix it. Here are some of the most effective solutions:
1. Recreate Outlook Profile
If the error is caused by a corrupted Outlook profile, you may need to recreate your profile. To do this, you need to first close Outlook and go to the Control Panel. Then, click on “Mail” and select “Show Profiles”. Click on “Add” to create a new profile and follow the prompts to set it up. Once you have created a new profile, open Outlook and check if the error is resolved.
2. Set Outlook as Default Mail Client Again
If the error is caused by incorrect default mail client settings, you may need to set Outlook as your default mail client again. To do this, go to the Control Panel and click on “Default Programs”. Then, select “Set your default programs” and choose Outlook from the list. Click on “Set this program as default” and click on “OK”. This should set Outlook as your default mail client and resolve the error.

Find Microsoft Office in the list and click on “Change”. Then, select “Repair” and follow the prompts to repair Outlook. If repairing Outlook does not work, you may need to uninstall and reinstall it.
4. Disable Antivirus or Firewall Temporarily
If the error is caused by antivirus or firewall settings, you may need to disable them temporarily. Sometimes, antivirus or firewall settings can block Outlook from accessing certain files or features, causing the error. To disable your antivirus or firewall, consult the documentation that came with the software. Once you have disabled them, try opening Outlook and see if the error is resolved.
5. Run Outlook in Safe Mode
Running Outlook in Safe Mode can also help fix this error. To do this, close Outlook and press the Windows key + R to open the Run dialog box. Type “outlook.exe /safe” and press Enter. This will start Outlook in Safe Mode, which disables any add-ins or extensions that may be causing the error. If the error does not occur in Safe Mode, it may be caused by an add-in or extension.

This error message typically occurs when the default mail client is not properly configured or when the system is unable to detect the default mail client. Some possible solutions to this issue include:
Re-registering the Outlook executable file by running the command “outlook.exe /safe” and then setting Outlook as the default mail client.
Checking if there are any other mail clients installed on the system that may be conflicting with Outlook. If there are, uninstall them and then set Outlook as the default mail client.
Checking the Windows Registry to ensure that the correct default mail client is set.
Verify if the shared drive has the correct permissions to open the email files.
Run the Outlook in the safe mode and check if the error still persists. If it does, then the issue might be related to the Outlook profile.
Try creating a new Outlook profile and see if that resolves the issue.
It is also recommended to check for updates for the Outlook and windows and perform a system restore if the problem persist.
The problem was that the user had “Preview Pane” enabled in Windows Explorer. It took a long time to find a solution to this problem but it was resolved when I turned off the “Preview Pane” option. The explorer was trying to open the MSG file in the preview pane but it couldn’t.
