Microsoft Edge is the new always up-to-date, ultrafast and modern browser in Windows 10 CBB It is not included in the Long-Term Servicing Build of Windows 10. Microsoft Edge doesn’t share favorites with IE, it has its own favorites store which is located here: %Userprofile%\appdata\local\packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\ac\MicrosoftEdge\User\Default\favorites
In Edge there is a built-in feature to copy favorites from IE, Chrome or Firefox. However if you are using folder redirection for IE favorites so they aren’t located under %userProfile%\Favorites anymore then you will be met with this error message when you try to copy the favorites from IE in the Edge browser.
I created a little PowerShell script that will copy the favorites from both a redirected and a non-redirect favorites folder that can be run in the user context to copy the favorites from IE to Edge. It also deletes the registry key necessary for Edge to read the new favorites, it also excludes $recycle.bin file that can exist in the redirected favorites folder.
I have uploaded the script to Technet Galleries, it can be found here: https://gallery.technet.microsoft.com/Powerhsell-script-to-copy-1e300de5
Note that Edge must have been started once so that all the registry keys are inplace. I am hoping that the Edge team will solve this for us in the future but until then launching and stopping the Edge browser when you build your reference image in MDT and then use Copyprofile during deployment solves the need to start Edge once before copying of the favorites are successful.
Thanks to my colleagues Johan and Petrus for assisting in the testing and verification.
I hope this can be useful.
