A couple of weeks earlier, I saw an interesting issue. It was a normal day as far as days go in support and in comes this issue, where the person in question wants to investigate or rather should I say automate the process of creating IRM settings on document libraries. I wasn't working on this issue and a colleague took this over. But then somewhere it was lurking, how the hell do you do that? The natural starting point is getting a site/web context and going down to the list and then getting dirty with the properties exposed by the particular SPList object. So after finishing what I had on my plate, I dug into figuring out how exactly to set the IRM settings for a list using the object model. So here goes:

**Step 1 Enable IRM on the farm**

SPWebService svc  =  SPFarm.Local.Services.GetValue<SPWebService>() ;  
 SPIrmSettings irmSettings     =  svc.IrmSettings ;  
 irmSettings.IrmRMSEnabled     = true;  
 //set true or false based on the situation  
irmSettings.IrmRMSUseAD       = true;  
 irmSettings.IrmRMSCertServer  =  "certificate server here" ;  
 irmSettings.IrmChanges        =  irmSettings.IrmChanges +  1 ;  
 svc.Update() ;

**Step2 Set the IRM properties for a document library**

SPSite site  = new  SPSite( "http:" ) ;  
 SPList spList  =  site.OpenWeb().Lists\[ "list\_name" \] ;  
 SPFolder folder  =  spList.RootFolder ;  
 spList.IrmEnabled  = true;  //corresponds to "Restrict permission to documents in this library on download"  
// BELOW SET=2, RESET=0  
folder.Properties\[ "vti\_irm\_IrmPrint"       \]  =  2 ;  // Allow users to print documents  
folder.Properties\[ "vti\_irm\_IrmVBA"         \]  =  2 ;  // Allow users to access content programmatically  
folder.Properties\[ "vti\_irm\_IrmOffline"     \]  =  2 ;  // Users must verify their credentials every nOfflineDays  
spList.IrmReject  = true;  // do not allow users to upload documents that do not support IRM  
spList.IrmExpire  = true;  //sto\[ restricting permissions to documents in this library on expiry date  
folder.Properties\[ "vti\_irm\_IrmOfflineDays" \]  =  nOfflineDays ;   
 // integer representing number of days after which user needs to verify credentials  
folder.Properties\[ "vti\_irm\_IrmExpireDate"  \]  =  dtExpire.ToString( "r" , CultureInfo.InvariantCulture) ;   
 // date on which to stop restricting IRM permissions to documents  
folder.Properties\[ "vti\_irm\_IrmTitle"       \]  =  "Permission Policy Title" ;  
 folder.Properties\[ "vti\_irm\_IrmDescription" \]  =  "Permission Policy Description" ;  
 folder.Update() ;  
 spList.Update() ;
