This article explains how to improve restrictions on the display of appointments replicated via the MetaDirectory AddOn Replicator for Microsoft® Exchange Webservice (EWS) in the ProCall Client tooltip when they are displayed without a subject.

The EWS calendar replicator uses the permissions configured in Microsoft Outlook or Microsoft Exchange Server. Check whether the user from Microsoft Exchange Server specified in the EWS calendar replicator has been granted the necessary access authorization for the subject. The access permissions set can be adjusted in the Microsoft Outlook calendar under "Calendar permissions".
