[Evolution] Cannot delete any mail

[Cliff Laine <lainecliff gmail com>]

I can't delete any email in Evolution. Every time I open Evolution,
deleted mail reappears in the inbox.

I have tried deleting the mail, then going into the Wastebasket,
highlighting all the mail, and pressing delete. This does nothing. I
have tried File > Empty Wastebasket. Again, nothing.

I have "Hide deleted messages" ticked.

Any ideas?
