If I was managing Apache web servers day after day I would have probably known the answer to that issue straight away. Instead I had to utilise Google quite a bit in order to find out how to add Office 2007 documents as mime type for the Domino web service: Microsoft Office 2007 documents do not open/save correctly when accessed over the web
Without changing the httpd.cnf file Word 2007 documents for example are recognised as “Compressed (zipped) Folder”, which makes it impossible to associate the file with Microsoft Office.
It’s not like Office 2007 isn’t around since about 2 years. How could this have slipped through the Lotus Domino 8.5.1 release by IBM?
