Hi,
My team and I are currently working on integrating a custom WOPI-Host and everything is going pretty good. While testing out different documents that will be used in the system to see the supported features and the reaction of Word Web App we found a document that is problematic.
First things first, we took a document that was in Word 97-2003 version (.doc) and converted it in Word Documents (.docx). We had to actually use the Word Desktop Convert functionality because using "Save As" wouldn't work. We found out that the document had Custom XML Data which was the reason that the "Save As" didn't work. So we did 2 version of the document in docx version. One that kept the Custom XML Data and one that didn't have it.
Now when we try to open the documents in the Word Web App, both trigger the same error: "Sorry, Word Web App can't edit this document because it appears to be corrupt.". What I don't really understand is that I can open them in the Desktop version of Word without any problems. Also, if it was simply the Custom XML Data that would prevent Word Web App to open the document, how come the version of the document without these Custom XML Data is still considered corrupted by the Word Web App.
If needed, I can send the documents in question (probably by email since I don't see an option to attach them to this question).
Thanks,
Patrick Racicot
