Outlook Issue: Could not perform this operation because the default mail client is not properly installed
I have had quite a spat of Microsoft Outlook issues recently. The issues have been so bad with the organizer and email client that I even upgraded to Microsoft Outlook 2007, experienced more issues, and then downgraded again.
In the case of this post, the email error that I kept getting the message via a pop-up window that "Could not perform this operation because the default mail client is not properly installed." whenever I clicked on a link in an email. What in the world was that?
Apparently the symptom that I experienced was a mis-nomer (surprise, surprise) for the real issue that was taking place. Somehow, between the installation of the upgrade to Microoft Office 2007 and then the subesquent downgrade to Microsoft Office 2003, Internet Explorer lost the default settings for the E-Mail program.
How did I fix it? All it took was a couple of easy steps:
1. Exit Microsoft Outlook.
2. Open up Internet Explorer and select Tools --> Internet Options. Then select the Programs tab from your optoins and change the E-mail default program to Outlook Express from Microsoft Outlook. Click on 'ok' to apply and exit.
3. Repeat the same step as above, however change the the program setting back to the Microsoft Office Outlook settings. Click on ok and exit Internet Explorer.
Now e-mail links in your Microsoft Outlook inbox should function normally when you click on them. No more "Could not perform this operation because the default mail client is not properly installed." error from Microsoft Outlook!
