There are different methods of importing Windows Mail folders, accounts, emails and contacts. Some of these methods create problems. I don't know exactly which method you have used. I have done a post found here on the method which I found the easiest and safest.
If I understand you correctly, the account is now stable and holding.
This means the only problem remaining is with the custom folder you created and not being able to drag/drop to it. Unfortunately, I don't know why this is so. You could try deleting it, rebooting and re-creating it.
However, if I were in your situation, and wanted a squeaky clean installation, as long as you have all the original emails and folders, (including custom made ones), intact in Vista Windows Mail, then I would import the whole thing from scratch as per the post I've mentioned above.
Part of that process is to totally delete all files in Local Folders in Windows 7, found under AppData (not program files),via the pathway shown below. This is the only way the import will work properly. But the beauty of it is that you're importing to a clean slate, with no inherent problems from past history. This is the pathway, however, to see AppData, you will need to change View settings to allow hidden folders to be visible:
Start orb --> User Name --> AppData --> Local --> Microsoft --> Windows Mail --> Local Folders
It imports all Accounts fully set up; All Local Folders & Custom created sub-folders in their correct place, (*Note: A custom folder must have an email in it, or it won't import). All you'll have to do to make the accounts operable is put in your user name and password when prompted by your ISP when you first open WinMail.exe.
Since you simply copy/paste the entire contents of Local Folders from AppData in Vista, your emails in Vista will remain intact. However, you will lose everything in WinMail in Windows 7. So if you've got any emails there that are not in Vista, first save these to a back-up storage folder or USB stick.
Hope this helps. Cheers PB :)
