Unable to move message to Trash
I have two email accounts on my iPhone: a gmail account and an exchange account. The gmail account is the default account.
On Wednesday, I deleted 3 emails from my PC on the exchange account that weren't deleted from my phone. I deleted numerous other emails before and since from my PC that correctly deleted from my phone, also.
I have tried to delete these messages from my phone, but I get an error message: Unable to Move Message - The message could not be moved to the mailbox Trash.
I've read several solutions on the web, but they all tell me to go to Settings/Mail/click on the Exchange account/click on the Account address/click on Advanced. There is no Advanced button in the Exchange account in Settings. The Advanced button does show up in the gmail (default) account.
Thanks in advance for your help.
iPhone 4, iOS 5
