The Global Address Book (GAL) is a directory of available contact information for CUMC, NYPH and Columbia University faculty, staff and students.
It can be accessed when using a CUMC email (@cumc.columbia.edu) account with Outlook or when logged in to the Outlook Web App.
The Outlook clients are in cached mode but they update the GAL every 24 hours and these distros still don't show up. While I was doing some testing of the old way (pure AD call) that we used to create DGs in E2k3, I found that once in a e2k10 environment there is a need to run the powershell command (Set-Distribution Group) to update the DG specifically the property "Hidden From Address Lists Enabled" with the appropriate value for it to show up in GAL.
Of course when you run this command, you will be prompted to upgrade the DG which seems to be affecting some attributes (ms Exchange Version, show In Address Book etc.).
We will select Address Lists from the List and click "add" at the bottom and then click "ok".
