Finally there is a built in way to add thumbnails of people in Exchange and Global Addresslist. In earlier Exchange versions there were no function to import pictures in to schema and therefore a lot of different scripts and third party tools was designed to import pictures. Now we can deliver this as a part of any other Exchange project. Office 2010 is built around showing thumbnail photo of users in E-mail, Global Address List, Communicator, and all other office products where you find a username. This is really an important part of the Unified Communications experience

Here are some facts:

• You need to activate the thumbnailPhoto attribute in schema to replicate to Global Catalog
• The attribute is limited to 10K in size
• The recommended thumbnail size is 96*96 pixels
• In Exchange PowerShell use the cmdlet Import-RecipientDataProperty
  • Import-RecipientDataProperty -Identity ”Bharat Suneja” -Picture -FileData ([Byte[]]$(Get-Content -Path ”C:\pictures\BharatSuneja.jpg” -Encoding Byte -ReadCount 0))
• After the thumbnails are uploaded you need to update OAB, so that it will point to AD for the images
  • Update-OfflineAddressBook “Default Offline Address Book”
• For true offline use, you could modify the ConfiguredAttributes of an OAB to make thumbnailPhoto a Value attribute
  • This will increase the size of the OAB so it need to be tested before deployed
