@Bharat: Getting the picture back out of AD is no problem in Visual Basic.Net ... It's really as easy as:
-----------
Dim myUser As New System.DirectoryServices.DirectoryEntry("LDAP://" & userDN)
Dim b() As Byte
b = myUser.Properties("thumbnailPhoto").Value
If b IsNot Nothing Then
picPreview.Image = Image.FromStream(New IO.MemoryStream(b))
End If
-----------
To get it into a picture box. The issue is getting it set as the user's account picture.
Also, I still haven't gotten the pictures to show up in Outlook 2010 Beta build 14.0.4536.1000. Do you know if it's supported in that build? Or should I contact the Office Beta team to try and figure out what went wrong?
Thanks again.
