Error on clicking "mailto" link

[Dipu]

hie,

I am facing a problem out here. I am using Internet Explorer as my webbrowser. From past few days, whenever I click on the mailto: link in my IE, several multiple IE windows opens up. Then I have to close all these unwanted IE windows manually. What is the cause of this issue ? and how do I resolve it ?

any ideas......

The cause of this problem may be due to one of the following reasons -

- Mailto handler is not set correctly.
- URL Protocol registry value is missing.
- Incorrect registry permissions for the mailto key.

I had also faced the similar issue where aound more than 50 windows of Internet Explorer opened up giving me following error -

"Could not perform this operation because the default mail client is not properly installed"

To resolve this issue, you first need to set default E-mail client.

• Click Start > select Run > type control inetcpl.cpl
• Select the Programs tab
• Choose another mail client from the E-mail dropdown list > click Apply
• Redo the procedure and set your preferred email client again.

If the above steps does not solve the issue, follow these steps to re-create the missing string value -

• Click Start > select Run > type Regedit.exe
• Navigate to the following branch: HKEY_LOCAL_MACHINE\Software\Classes\mailto
• From the Edit menu, select New > click String Value.
• Type URL Protocol as the name of the new String Value
• Exit Registry Editor.

If you receive an error when accessing the "mailto" registry key, then it must be due to incorrect Permissions. Follow these steps to fix the Permissions for that key and subkeys:

Taking ownership of the mailto key and sub-keys

• Start Regedit.exe and navigate to the following branch: HKEY_LOCAL_MACHINE\Software\Classes\mailto[/b]
• On the Edit menu, click Permissions
• Click Advanced > click the Owner tab
• Under Change owner to, click the new owner (your user account)
• Place a checkmark near Replace owner on subcontainers and objects
• Click OK

Setting the Permissions for the mailto key

Note -
Make sure that the users have Read access to the above registry key. Administrators and the SYSTEM group should have Full Control over the above key, and Users should have Read access.

• Start Regedit.exe and navigate to the following branch: HKEY_LOCAL_MACHINE\Software\Classes\mailto
  
  
• On the Edit menu, click Permissions. Configure the permissions as mentioned below:
  Object ------------- Permissions
  Creator Owner ----- Full Control
  Administrators ----- Full Control
  Users -------------- Read
  System ------------ Full Control
  
  
• If an object name is missing, click the Add button to add an user or group.
• Click the Advanced button
• Select the Replace permission entries on all child objects with entries shown here that apply to child objects checkbox.
• Deselect the []Inherit from parent the permission entries that apply to child objects. Include these with entries explicitly defined here checkbox.
• Click Apply > then click Yes when you are prompted to continue.
• Click OK > click OK again.
• Exit the Registry editor.
