The "not so simple" Simple Display Name
Consider the following scenario:
This applies both to Exchange 2007 and Exchange 2010.
We have two Users :
User1 ( User1@mp3.lol ):
Display Name : User 1
Simple DisplayName : User One
User2 ( User2@mp3.lol ):
Display Name : User 2
Simple Display Name : N/A ( not configured )
We have one Remote-Domain: Default.
We want to use the Simple Display Name for External Emails and we configure:
Set-RemoteDomain “Default” –UseSimpleDisplayName $true
User1 and User2 start sending External Emails:
When the UseSimpleDisplayName Parameter on the Default Remote Domain is set to $True we
check for the Simple Display Name attribute to be set on the sending User and attach it to his <SMTP Address>.
If a User doesn’t have a Simple Display Name, we will send using the following format : “SMTP Address <SMTPAddress>”.
You probably would say: Why don’t we use the Simple Display Name when this is configured, and for the Users where this isn’t configured, use the Display Name?
Answer here would be: this is the design that we currently have in the Products.
What can you do to “change” this?
Well, you could create a script which should populate the Simple Display Name for the users who have it empty, with their Display Name.
Or you could just come back to the UseSimpleDisplayName $false and use the Display Name.
What you should take into consideration here is the character sets that each of these fields support:
For example, german Umlauts ( öäü ) are not included in IA5.
