Consider the following scenario:
- In a Microsoft Exchange Server environment, the First Name section or the Last Name section of a user object includes one or more of the following double-coded characters:
ü, Ü, Ö, ö, Ä, ä, Å, å, ß, ÿ
- The email address policy uses the FirstName (givenName) or LastName (surName) field.
In this scenario, the double-coded characters are displayed incorrectly in the user email address. Exchange Server substitutes ue for ü for, oe for ö, and so on. For example, the email address for user Ömer Ekici appears as Oemer.Ekici@contoso.com.
This problem occurs when the regional setting for Windows Server is English.
To resolve this problem, use one of the following methods.
Method 1: Change the email address policy
Change the email address policy for correct character replacement. For example, say the current email address policy is %firstname.lastname@example.org and the problem is with the ü and ö characters. In this case, change the email address policy to %rüu%röo%g.%rüu%röoemail@example.com.
To learn how to change the email address policy, see KB 822447: How to Modify an SMTP E-Mail Address by Using Recipient Policies.
Method 2: Change the regional setting of Windows Server
Use this method if Exchange server is running on Windows Server 2008 R2 or a later version of Windows Server.
Change the regional setting to a language that supports double-coded characters. For example, you can change the regional format to Turkish, Swedish, German, Finnish, etc. To do this, follow these steps:
- Open the Region item in from Control Panel.
- On the Formats tab, set the format to Turkish, Swedish, German, Finnish, etc.
- On the Administrative tab, change the system locale to the same language that you set in step 2.
- Click Copy settings, select Welcome screen and system accounts and New user accounts, and then click OK.
- Restart Windows Server.
