ownCloud WOPI Proxy for O365

<!--HTML-->Content collaboration is an essential component of modern companies. Using WOPI protocols, companies can allow employees to directly edit their cloud files in the web browser. Microsoft has allowed the editing of Word, Excel, and PowerPoint files within a web browser for several years, but the company using this feature was initially required to host their own Microsoft Office Online Server (OOS). For companies that already have an Office subscription and do not wish to host their own OOS, ownCloud (oC) has proudly joined Microsoft’s Office Cloud Storage Partner Program (CSPP). Now, via a proxy server set up by oC, customers will soon be able to view/edit documents online via the oC Web UI.
