Dan asks:
"My inbox is not being Auto archived while the rest of my folders are. How do Ifix it?"

Is the Inbox folder enabled for AutoArchiving? Right click on it and choose Properties, then go to the AutoArchive tab to enable it.

If you want almost all folders enabled with the same settings, set the autoarchive defaults in Tools, Options, Other tab, AutoArchive button and apply it to all folders, then change the AutoArchive setting on each folder that requires different settings (using the right click, Properties method above).
