Hi I recently moved from Exchange 2003 to Exchange 2010. A week after the transition one user noticed that in his Sent items folder in Outlook 2007 under Sender suddenly there is no longer his name, but the whole LegacyExchangeDN sausage... BTW, the user is my bosses boss. Help me please. Global Address List issue?

You call this a transition. The Exchange 2010 server is in the same organization and forest as the Exchange 2003 server? Or is it a migration where you crossed forests?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi! Same forest, moved mailboxes from Exchange 2003 to 2010 SP1. Radojica

How did you move them? That problem might exist if you moved mailboxes between organizations. Please describe in more detail what you are seeing.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

It's the same organisation. Installed two Exchange 2010 SP1 servers, typical roles, put them in a DAG group, moved mailboxes. After about one week a user noticed that in the Sent items folder in Outlook under Sender for mails he sent Outlook suddenly displays LegacyExchangeDN instead of the Simple Name. An hour before it was OK, under Sender there was Simple Name. Radojica

Update: Las week i did - Transfere the default Offline Address Book to the new Exchange Server 2010 server - Convert the Address List Set-AddressList “All Users” –IncludedRecipients MailboxUsers Set-AddressList “All Groups” –IncludedRecipients Mailgroups Set-AddressList “All Contacts” –IncludedRecipients MailContacts Set-AddressList "Public Folders" -RecipientFilter { RecipientType -eq 'PublicFolder' } Set-GlobalAddressList "Default Global Address List" -RecipientFilter {(Alias -ne $null -and (ObjectClass -eq 'user' -or ObjectClass -eq 'contact' -or ObjectClass -eq 'msExchSystemMailbox' -or ObjectClass -eq 'msExchDynamicDistributionList' -or ObjectClass -eq 'group' -or ObjectClass -eq 'publicFolder'))} - Convert E-mail Address Policy Get-EmailAddressPolicy | where {$_.RecipientFilterType –eq “Legacy”} | Set-EmailAddressPolicy –IncludedRecipients AllRecipients Now it seems to be OK again, Outlook 2007 displays in Sent items folder the Simple Name for the sender again.
