Microsoft Exchange email won't send

I have Exchange synced to my em Client, but randomly this morning it won’t send any of my messages. I can receive messages, but the outgoing just are sitting in the out box. There is no error message or anything they just sit there.

My accounts doesn’t seem to have any smtp info either so I can’t check or try changing anything…

Hello Denise,
Exchange Web Protocol is for both incoming and outgoing messages, so there is indeed no SMTP setting.
However, it is very strange that you get no error messages if the messages cannot be sent.
Can you go to Menu>Tools>Operations and copy the content of the Log tab after hitting ‘Refresh’?
You can click inside the log, CTRL+A to select all lines and then copy and paste it here.
