I have a Cyrus-IMAP server with altnamespace:yes and unixhierarchysep: yes. I want my sent messages to be stored on server, the INBOX.Sent being the most obvious choice. Setting this in Apple Mail was easy (Mailboxes>Use this folder for...>Sent). With Outlook 2007, however, I've run into a strange problem.
The Outlook documentation suggests:
" ... In the Internet E-mail Settings dialog box, click the Folders tab. Folders tab in Internet E-mail Settings dialog box To choose a custom folder for saving your sent items, click Choose an existing folder or create a new folder to save your sent items for this account in." (http://office.microsoft.com/en-us/outlook-help/change-where-sent-e-mail-messages-are-saved-HA010164216.aspx)
OK, I choose Inbox.Sent, but the sent messages are still saved in a local Outlook folder. If I try to move them to Inbox.Sent, I get an error message: server said the mailbox does not exist. Yes, what does exist, is INBOX.Sent, and both SquirrelMail and Apple Mail store sent messages there. Now, if I create a subfolder in Inbox.Sent, like Inbox/Sent/test, it DOES exist from the server perspective (and sent mail can be stored there). But Inbox/Sent still cannot be used for that, and INBOX.Sent is not visible in any folder list.
The most bizarre is that Outlook recognizes the existence of INBOX.Sent by storing its own test messages there (those generated while creating the account).
After googling half a day I'm out of wits. Please, help.
