We use Microsoft exchange 2007 and outlook 2010 and Active directory running on windows 2012 server.
Nine months ago we had a user who left our organisation and her account was not deleted from the Active Directory. Today a new user has joined our organisation with the same name. So I deleted the old user account from the AD and remove the mail box as well by using the following command.
Remove-Mailbox -Database <Database-Name> -StoreMailboxIdentity <MailboxGuid> -confirm:$true.
After deleting the old user account I created a new user account 7 hours ago with the same name and user ID.
I went to OWA and did a search and I can see the name of the new user populated and when I send an email from my OWA , the email is received to the new user (ABA) inbox.
But when I go to my outlook 2010 client and send an email to ABA@myorganisation.sch.uk , I get delivery failed message, please see below.
Any help to resolve this much appreciated. Many thanks
