No, I am not using SSO, when opening the document, the office extention will open a dialog promping me to input username and password.

I take macro script as an example to demonstrate that word COM object model cannot be used after encripted. Actually you can reproduce the same problem when you manipulate word document through COM interface using any programming language.For example, you can create a text document with the following VBscript:_____________________________________________________set a = createobject("Word.Application")set doc = a.Documents.Open("E:\temp\test.docx")msgbox doc.Fields.countdoc.closea.quit___________...

Hi, two months passed, any progress on this? Thanks.

Sorry, watermark can be shown in pagelayout view of word and excel. But, our customer want to use watermark to warn user not to capture the screen and distrubute the document without permition. If watermark can only be shown in pagelayout view, then this purpose cannot be reached because user can change to other view and capture the screen without capturing the watermark . Is this a feature by design? or do you have any plan to improve it ?

Today we did more test in several environments. :1, Problem can be reproduced with Microsoft Office Word 2007 (12.0.6668.5000) SP3 MSO (12.0.6662.5000) or above. Problem cannot be reprodced with Office 2007 and no sevice pack installed.2, Excel 2007 or above can also reproduce similar problem when saving file in the file extention of xls, but Powerpoint doesn't have similar problem.3, Watermark doesn't show with both excel and powerpoint.This is the new problem which we didn't find out before.

I will do more tests and post the test results here on next monday.Thank you very much.
