Does anyone know how to resolve this recurring error message from Outlook 2013 running on a Windows 8.1 Virtual Machine (using Parallels on a Mac).
Each time a Calendar item is edited or accessed, Outlook generates the following message. "The form region "Apple.DAV.Appointment" cannot be opened. The form region manifest contains invalid XML."
The only option available is to click OK, until it recurs.
Would appreciate any help!!
Thanks in advance.
