[solved] Issue: Published calendars // limitations OWA

An important security update for Microsoft Exchange is currently affecting the functionality of the Outlook Web App (OWA) webmail application, which is accessible at msx.tu-dresden.de.

Until Microsoft releases further updates, the following limitations apply when using OWA:

• Images sent directly within the email body (inline images) may not display correctly or at all in the recipient’s OWA reading pane. As a workaround, send images as email attachments or use the Outlook desktop client to view them.
• It is not possible to use published calendars (links ending in .html or .ics). When you click on these links, you will receive an error message with the following content:
