I set up my outlook.com account with the OS X (10.9.1) Mail app using IMAP, pretty much as suggested in this link except that the latest mail app has no option to keep the account offline before it is created.
The connection to outlook.com appears to be fine, as my sent items, junk, etc. folders are all populated with up-to-date mail, and I can send mails from the account, but my inbox is completely empty.
I've tried a bunch of suggestions such as deleting the pertinent mailbox folder from
~/Library/Mail/V2 and also the
EnvelopeIndex files from
MailData to try and force a rebuild of the mailbox, but it seems these are to no avail.
Not sure if this info will be of help, but in the menu items the
Get New Mail and
Rebuild commands are greyed out for this account too.
It seems like this is a common enough problem, but none of the solutions I've seen work for me. Anybody got any ideas?
