Office Outlook
Since migrating my work mailbox from Novell GroupWise to Microsoft Exchange my Junk E-mail folder within Microsoft Outlook was renamed Junk E-mail1. If I tried to rename the folder from within Outlook the option was greyed out so there seemed no simple way to do this, it annoyed me to be honest!
Well today I have solved it and my Junk E-mail1 folder is now labeled Junk E-mail. How did I do this? It was really really simple, all I needed to do was to close Outlook then relaunch it once with outlook.exe /resetfoldernames
That was it, like I said simple!
