In our fresh installation of GW2014 the Webaccess is not functioning correctly. Some things we notice:

1. Signatures are not displayed (empty box) and when a mail prompts for a signature, the window does not close and the email is not send.
2. Deleting an email works. But the line of the email is displayed until the moment of a manual refresh in the browser. The same goes for reading mails and showing that an email is read.

Anyone with the same experiences?
