One of my email distribution groups got deleted from Exchange 2010 (I fumble fingered it). I recreated it on the server, but it doesn't work anymore on Outlook.
I am unable to send email with the Distribution Group Alias , the email address of the Distribution Group and I cannot expand the list. I suspected a stale cache entry so I deleted the cached entry for the Distribution Group on Outlook and then I forced Outlook to "Download the Global Address Book" to get it to work.
That is not a good long term solution for a bunch of users.
Why is this failing in the first place?
How can I address the issue long term?
