Tool that bulk imports or removes User pictures

Simple Tool that bulk imports or removes user pictures, based on AD Group Membership.
If a user is in both groups, the picture will be removed!
Idea based on my old tool to import Active Directory pictures.
They are a bit to tiny, so I use Exchange now to make them look better in Exchange and Skype.

The tool will not check the pictures. As long as a picture exists, it will try to import it. Then the Exchange Server might reject the import, and you will get a warning. Same for users with non existing Mailboxes: The Tool will not check anything for the User before it tries to import the picture.

The Pictures should be in the JPG format and not larger than 648x648px. With a depth of 24 bits, each picture has around 200-250 kilobytes. Keep that in mind if you load a big bunch of pictures.

The following formats are used:

  • 48x48px – Active Directory thumbnailPhoto
  • 96x96px – Outlook, Outlook Web Access, Lync/Skype and SharePoint
  • 648x648px – Lync/Skype Clients and Lync/Skype Web App

Is your environment to small for an Exchange High-Availability?

Paul Cunningham wrote a very interesting article about that topic!
His key point here: No! possibly not.

And I agree a 100 percent!

What makes that so interesting: I had the same discussion with a customer last week!
They plan to move to the cloud (Office 365) soon. However, the customers business needs the mail service available. Now!

Here is my approach for the customer:

  • Install a second Exchange 2013 Server (virtual)
  • Establish a HAProxy based Load Balancer
  • Configure Database Availability Groups (DAG)
  • Configure a Witness-Server (Existing HA solution was used) – Could be a cheap Azure Service as well
