Trash Will not Empty

I have imported some emails and folders from outlook and now I cant empty them form trash!
No matter what I try it leaves the folders and even re-creates them under _1 _2 _3 etc…

I have tried delting from Trash and they still re-appear when refreshed! I have checked on my mail server and they do not appear there so it’s a local store issue?

Has someone else had this issue?

Work Around:

I have just found out how to get over this issue, if you delete Folders that contain child folders you must UNDER TRASH FOLDER, ‘Delete’ other folders up to parent folder before the trash will empty…
