Microsoft Outlook is known for its ability to synchronize users' emails from the web to its desktop-based application, allowing users to send/receive emails, manage contacts, add notes, and more. In addition to individual users, many organizations rely on Outlook as their email client. Despite its widespread popularity and diverse features, users may encounter various issues while using Outlook. One of the most common issues reported by a majority of Outlook users is the appearance of pop-up error messages like "Outlook is not recognized as the default email client," typically displayed as an alert as shown in the following screenshot:
Users often encounter these error messages when they try to send an email using the 'File' or 'Send by email' command in Outlook. Additionally, the issue of 'Outlook is not recognized as the default email client' can be attributed to other factors, including bit configuration and improper installation of the Office Suite of products.
Here are some of the most common reasons behind encountering the 'Outlook not recognized as the default email client' error:
One direct method to fix this issue is that you can check and assign Outlook as the default email client via the Control Panel settings.
To verify and assign Outlook as your default email client, following these simple steps:
If you encounter errors like "Either there is no default mail client or the current mail client cannot fulfill the messaging request" even when Outlook is already set as the default email client, it could be due to either using a different bit version of Outlook or installing the application after installing the MS Office Suite.
Verify the bit configuration of your existing Outlook application and consider reinstalling the appropriate version based on the configuration of other programs installed on your computer. Generally, a 64-bit configuration for Outlook is recommended when dealing with large data files (approximately 2GB or more), especially if you're using applications like MS Excel and MS Access. However, it is possible to work with a 64-bit Outlook even if other programs are configured as 32-bit by making specific modifications to the system's Registry settings.
In case you have installed Outlook with the MS Office Suite, you can repair the Office installation manually through the Control Panel.
In some cases, the issue arises when Microsoft Outlook 2010 Click-to-Run (C2R) suite is installed on a virtual hard drive, making the application invisible to other applications. This is the underlying cause of the problem.
Here, users can uninstall this suite and then download and install the MSI to get the Microsoft Outlook application.
However, if you prefer not to uninstall the C2R suite for Microsoft Outlook 2010, you can make changes to the Windows Registry settings. Here are the steps to do so:
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Outlook64Bridge\DLLPathEx
And the path to be assigned to the keys is – (example) “C:\WINDOWS\x86_microsoft-windows- \xxxxxxxxxxxxxxxxxxx mapi32.dll”
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail"Outlook64Bridge"
By now, you've likely resolved the 'Outlook is not recognized as the default email client' error. However, what if your MS Outlook application becomes completely inaccessible despite your efforts to regain access? Outlook inaccessibility is often linked to the corruption or damage of Outlook's PST files.
