I've had this issue and it's been bugging me forever... I've searched and I can't seem to find an answer.
I have a personal email account through fastmail.fm. On my laptop all of my folders display nicely (meaning... if I open it I'll see:
Accountant Inbox Saved Spam ....
And so on.
But, on my desktop, the folders are displayed in a hierarchy. If I open the mail account I'm only shown the inbox. I then have to click on the + sign to the left of the inbox to see all the other folders. So... how can I take what my desktop is displaying now and get it to display like my laptop does?
Outlook's IMAP implementation is not very good. It's great for POP accounts, but IMAP is a real pain. I've tested Outlook IMAP mail with several different providers, and I got different performance with each one.
If you have an Exchange server then it's easy to use the same mail profile wherever you go.
Is it just the expanded folders in your profiles that's different? I was wondering whether something like the Save My Settings Wizard [support.microsoft.com] would be worth investigating.
