We have a problem with the sort order in the Global Address List:
German Umlauts (ö, ä, ü) are sorted like "o, a, u" (dictionary sort order) - but they should be sorted like "oe, ae, ue" (phone book sort order).
We use Exchange 2007 Transport Hubs and Mailbox Cluster, and Outlook 2007.
We do not use Cached Mode and Offline Address Book.
On the DCs, THs, mailbox servers and on the client, the Regional and Language format is German (Germany), and I have changed the sorting method from Dictionary to Phone Book (DIN).
In AD Users and Computers, the sort order is now correct (i.e. "phone book" like).
However, in the Exchange Management Console and in Outlook, the sort order is still wrong (i.e. "dictionary" like).
How do I change the sort order in the Outlook Address Book?
