How do you organize multiple mailboxes for each accepted domain with the same local part?

Question

Let's say we are aceppting emails for the two domains wine-and-cheese.com and beer-and-pretzels.com.
I plan to create two mailboxes [email protected] and [email protected]
By default, the local part of the SMTP address uses the alias, which is the same as the sAMAccountName. Since I cannot have two AD users with the same sAMAccountName, I choose to name them "info-wine" and "info-beer". The result is, that
I have two mailboxes with the address [email protected] and [email protected], respectively.
One thing I could think of would be to manually add [email protected] and [email protected] to the corresponding mailboxes. I prefer to avoid anything that has to be done manually.
Another idea, that involves manual editing is, to change the aliases of both mailboxes to "info", but that results in having the second mailbox create the SMTP address info2@….
I am very interested how you handle those situations, particularly in bigger companies with more than 50 employees and 75 mailboxes.

Answer 1

Hi ,
Alright , based on my knowledge i have given some points please have a look in to this.
Step 1 :
Please create the first user account on AD in the below format.
info as the first name in AD
wine as the last name in AD
Then please create the second user account on the AD in the below format.
info as the first name in AD
beer as the last name in AD
Step 2 :
Then you need to have the email address policy with the custom type attribute which should apply the email address based upon the first name.So that all the email address will have the first name (i.e ) "info" on the prefix.
Custom type attribute should have to be like
%[email protected]
%[email protected]
%[email protected]
%[email protected]
Note : The custom type attribute which is created first will be the primary address for all those mailboxes.In the above example
@wine.com will be the primary smtp address for those mailboxes .In case if you want some set of mailboxes need to have the suffix @wine.com as the primary smtp address and some set of mailboxes to have the suffix @beer.com as the primary smtp
address then you need to create the separate email address policy with rules.
