Tom_Croll I have tried to find an alternative email application, as a Mac user there are quite a few to choose from. However, none of them seem to give me what the Old Outlook does, namely easy connectivity to the other applications I use such as Word, Excel and Powerpoint. Apple Mail is very good, but still seems to lack something that I can't quite put my finger on...
So at the moment I'm having to use Old Outlook with the Yahoo/IMAP issue. This means I have to use Yahoo mail browser to delete anything as Old Outlook doesn't do it anymore since an update. Support know about this and confirmed to me that its a bug, but your guess is as good as mine as far as when they fix it... Or if they do, as they say that New outlook fixes it! But then of course you dive into dozens of issues with that!
