Unspecified error when adding a link to Favorites in Windows 7

After reading the post Folder Redirection for Favorites on the Same Machine at the IE Team blog, I relocated my Favorites folder to a different drive. After the relocation, when I tried to add a URL to Favorites, I received the following error:

Unable to create 'Title':

Unspecified error

The solution is to set the integrity level to Low for the relocated Favorites folder. This article has a detailed writeup, and also provides a script that can automate the setting for you. Use one of the two methods below:

Method 1

Download fix_fav_il.vbs and save to Desktop. Double-click the file to run it. Click Continue when you see the User Account Control elevation prompt. The script will open an elevated Command Prompt window and fix the integrity level setting automatically. Once done, you should now see this message:

processed file: favorites
Successfully processed 1 files; Failed processing 0 files

Type EXIT to close the Command Prompt window.

Method 2

1. Click Start, type shell:favorites , and press Enter.
2. The Favorites folder of your user account will open. Copy the full path shown in the Address Bar.
3. Open an admin Command Prompt.
4. Type the following command:

   icacls <favoritespath> /setintegritylevel (OI)(CI)low

   Note: Replace the tag <favoritespath> with the actual path to your Favorites folder, enclosed with double-quotes)

   Example:

   icacls "D:\My Favorites" /setintegritylevel (OI)(CI)low

   You should now see this message:

   processed file: favorites
   Successfully processed 1 files; Failed processing 0 files
   

5. Optionally, to verify if the integrity level is correctly set for the Favorites folder, run the icacls command followed by the Favorites folder path:

   icacls "D:\My Favorites"

   You should see the following line in the output:

   Mandatory Label\Low Mandatory Level:(OI)(CI)(NW)

6. Type EXIT to close the Command Prompt window.

You should be able to add an URL to Favorites now. Reportedly, this problem occurs as Internet Explorer in Windows Vista and Windows 7 runs under Protected mode (low integrity level) by default, and therefore will only be able to modify objects marked with a low integrity level in their system ACLs.

When you relocate the Favorites to a different drive, you need to set the integrity level for the relocated folder, so that Internet Explorer (Protected mode) can write to it. This problem does not seem to occur if the Favorites folder is located within your user profile home directory.
