I'm using EAS on my SM 13 build 5535 Enterprise server.  I have a few messages in my iPhone that for whatever reason will not delete, they keep showing unread and keep coming back after attempts to delete them.  When I delete them from the iOS Mail app I get a message:

 

"Unable to Move Message"

"The message could not be moved to the mailbox Trash."

 

I logged in to web mail and the messages are not there.  How can I resolve this?

 

Thank you
