Hmmmm.....sounds like the sync in not the problem, darn.
I have just the one account, my work email, on Outlook. We use an email vendor that has both POP3 and IMAP servers. Earlier today the Admin there told me she saw my sent emails on the server and it sending/making it to my phone.
I do not know if its subscribed in Outlook. I have gone in to Account Settings>My Account>More settings like you said earlier and see the Folder Tree with Inbox,Drafts,Junk,Set but that is NOT subscribing is it??????
No changes when I lose the data. All I have to do is click on the Sent box and it reverts to the "POP3 version", meaning what my Inbox looked like before I made the switch.
