When you first?set up your iPhone to check your email account using IMAP, you may not see the Sent, Trash, Drafts, and Junk folders. Typically, these folders are in your INBOX and you'll need to set the prefix path for it to work correctly.
How to subscribe to folders
- If you set up the IMAP mail account on your iPhone, you may not ?find the IMAP folders in your Inbox folder. If this is the case, you'll need to specify the IMAP path prefix.
- You can enter in the IMAP path prefix by going to Settings > Mail > Account > Advanced > IMAP Path Prefix.
- Enter the word "INBOX" (use all caps) and save the setting. Now, your folders should appear as subfolders in the Inbox.?
