I have a single message in Mail on my iPhone 4 that just cannot be deleted. I get a popup saying Unable to move message - The message could not be moved to the trash folder.
I'm using the latest version of iOS. The account is an Exchange Active Sync account and deleting other messages is not a problem. I also use the same Exchange account from Outlook on my desktop and the message in question does not exist in Outlook. It only shows in Mail on iPhone.
I also have an another IMAP account on my iPhone and deleting isn't a problem on that account.
How can I remove this rogue message?
