Issue

Can't open a document in IRM enabled document library in SharePoint 2010

Issue in Brief

 I’ve enabled IRM from Central Administration (I’m using Active Directory integrated RMS). Now, in the document library settings, In the document library settings, I’ve checked the restrict permission to documents in this library on download Also i gave permission policy title and Permission policy description remaining are unchecked. Now when I try to open the document from document library

When I tried to open Excel I got following error

Microsoft Office Excel cannot access the file 'http://mossservername/Documents/Filename.xlsx'. There are several possible reasons:

·         The file name or path does not exist.

·         The file is being used by another program.

·         The workbook you are trying to save has the same name as a currently open workbook.

When I tried to open Word , I got following error

Microsoft Office Word:

"http://mossservername/Documents/Filename.doc" does not exist.Check your spelling or try another path

Then I simply removed the IRM permission policy from document library and then tried accessing the document. This time it opened.

I got same error when I open from Windows Server 2008 R2 as well as XP machine

Following Things I have tried but no luck

On the Internet Explorer à Tools à Internet Options à Advanced tab à click Restore defaults button à Click "OK" to finish --- No luck

Run one of the Office 2010 application (e.g. Word 2010).

  Click on File menu, and select Options.

  In the “Options” dialog, select Trust Center in the left pane.

  Click on Trust Center Settings in the right pane.
