Change a .pst display name by code

[Rolando Tonin]

I’m developing an Outlook2007
AddIn in C# with Visual Studio 2008 and VSTO 3.0.
I create an .pst file with this code:

this.DefaultNameSpace.AddStoreEx(@"C:\DATI\IDROESSE\IDROESSE.PST",
OlStoreType.olStoreDefault);

Now I want to change the default displayName "Personal Folder" (Italian
speak: "Cartelle Personali") with my company name. First I get the object
store:

private Store CheckStore(string storePath)
{
foreach (Store obj in this.DefaultNameSpace.Stores)
{
if (obj.FilePath == storePath)
return obj;
}
return null;
}
and, conseguently, add this code after create .pst file:

this.DefaultNameSpace.AddStoreEx(@"C:\DATI\IDROESSE\IDROESSE.PST",
OlStoreType.olStoreDefault);
Store sto = this.CheckStore(@"C:\DATI\IDROESSE\IDROESSE.PST");
if (sto != null)

sto.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3001001E", "Idroesse");

the call to SetProperty generate an UnauthorizedAccessException. The
permission on the path C:\DATI\IDROESSE\ is full control for each Domain
Users. Why I get an Exception? How can I resolve the problem?
thanks in advance

PR_DISPLAY_NAME is read only for a store, it's set by the store provider.
You would have to write your own store provider in Extended MAPI to be able
to set that property as desired.

Extended MAPI?

Extended MAPI is programmed only in unmanaged C++ or Delphi, you can't
program it in C# or other managed code. Learning enough Extended MAPI to
actually write a store provider is a long process and has a very steep
learning curve. MAPI is not an easy interface to learn well enough to
actually write a store provider.
