Recently I observed this issue during the migration of Exchange 2010 to Exchange 2016. Following are the symptoms noticed not for all but for very few users (less than 1%).

1. Unable to do Deep search on Outlook Address Book (Cached mode), such as with phone number, department etc.
2. Unable to succeed “Test E-mail AutoConfiguration” test from Outlook
3. Availability information were not displaying
4. Outlook returns following error while configuring profile,
"An encrypted connection to your mail server is not available.
Click next to attempt using an unencrypted connection."

Outlook New Profile Error

And similar other symptoms which occurs due to inadequate autodiscover information.

Suspected Reason and Solution

As you may aware, the mailbox move disconnects the Exchange 2010 mailboxes and connects the Exchange 2016 mailbox during the “Completing” stage if migration/move process. Which means, following stale information are present in the infra,

1. Mailbox Move for each user in the Migration batch
2. Disconnected Mailboxes at Exchange 2010 infra

The issue happens (I assume) because of the incomplete replication of information, and possibly due to the conflicts between connected and disconnected mailboxes. The solution in my case was fairly simple,

1. Remove the “Completed” move request against the user
        2. Restart "MSExchangeAutodiscoverAppPool" WebappPool on all Exchange 2016 servers "Restart-WebAppPool MSExchangeAutodiscoverAppPool"
3. Wait for 10 – 20 minutes, and try to test the autodiscover

The above helped me to restore the services back for the user who impacted. Share your experience in the form of comments.

Couple of weeks back, I was in preparation for a small script which would help me in import the user thumbnail into Active Directory. Fortunately, I received an email showcasing about one such free product from Exclaimer “Exclaimer Outlook Photos”. This software is Simply Superb, and I confidently can say that you never need to look for any other tool to manage your outlook photos.

Exclaimer Outlook Photos lets you import photos into the Active Directory to give everyone a photo portrait in the Outlook People Pane, their SharePoint profile and on Microsoft Lync. The software is a complete package with immense range of GUI Management features such as view, import, edit etc.


Outlook Photos is completely free. You get full functionality the moment you download: no license keys or no paid set-up. There is also no need to install it on your Domain Controller or Exchange server.

Plus, with Outlook Photos, you get all the additional benefits you would expect from choosing a solution from one of the world's leading email utility companies.


Don’t worry about learning Active Directory or PowerShell commands and go straight to importing, editing and storing photos in Active Directory. Batch-import feature allows importing multiple photos at once by selecting the folder or drive with your photos and migrate them all in a single click. It auto-matches pictures to names or other data in the Active Directory e.g. matching the user 'Karen Green' with her photo in 'KarenGreen.jpg' so you don't have to.

Crop and Resize Photos

The major worry to me was to tackle the size and resolution of the photo. With this excellent tool, the photos are automatically cropped and adjusted if they are not the right size. Following snapshot shows the mouse over address book popup in outlook.

In addition, this software helps you to,

- Review the photos users already have and decide whether to replace them.
