Website deletion issues

I often get problems when I delete email using the web client.  I have tried using different browsers (e.g., Chrome, Firefox):

  • Sometimes emails selected don't get deleted when I click the delete button
  • Sometimes emails that I have not selected for deletion, gets deleted. It doesn't matter if the the email has been read or not.   I now have to review the deleted items folder before emptying it.
  • Before I became aware of this issue, I lost many emails without knowing how it happened

Has anybody else experienced similar issues, and maybe know a workaround to solve this issue?
