Stop error logging

I clicked delete when the Trash folder was highlighted and not the individual email I wanted delete. I keep getting an error message saying the Trash folder cannot be deleted. How can i stop this action/error message please?

Clicking on OK should close the error.

If not, restart eM Client.

The error comes from the (exchange) server and is marked thus (there is no Ok option)

As it is an Exchange account, you could try removing the account from eM Client, then adding it again. See if that makes a difference.
