We are finding ZUGFeRD to be a key requirement for German customers, that is not satisfied by the XRechnung version supported by standard. It feels that the majority of German businesses will prefer ZUGFeRD due to its human-readable PDF-first approach, as not every customer/vendor will be running systems that can ingest the XRechnung and extract any embedded PDF.Native support for ZUGFeRD (including attaching the XML to the PDF in a PDF/A-3 compliant fashion) would be far better than having to rely on non-optimal third party solutions or building middleware
This highlights a clear limitation in the current mailbox configuration experience. Allowing administrators to directly modify the “Delete Emails after Processing” setting from the UI would greatly simplify management, reduce reliance on non-intuitive workarounds, and better support real-world Exchange Online integration scenarios. This improvement would enhance usability, maintainability, and overall admin efficiency.
