Need to add new email address format to entire Exchange domain

A decision was made today to change the format of my company's email addresses. Currently we are using We are growing quickly and need are switching to the format

There are 35 people in my organization and I would prefer not to visit each AD profile to manually add the new email address. Is there a way to add it manually through GP or Recipient Policy somehow?

Yes -> add to Recipient policy
and set it to default SMTP...

or if this is not enough, read this
The best way to go about this would be a script, I would think - I don't know of a gpo that would change existing mailboxes
Here's a good link taling about scripting.

honestly I think, for 35 people, if you are not already familiar with scripting, it's probably easier to change one by one in ADUC.
Its a easier way..

Go to Recipient Policies under Exchange, then take properties on Default Policy.
Under "E-Mail Addresses (Policy)" just add new SMTP-adress and the script for

For example %råa%rÅA%räa%rÄA%röo%rÖ will generate (this including the swedish åäö if ju add a account name Östen it will automaticly generate the adress Osten)

And when the Exchange System Manager ask: "Do you want to update all corresponding recipient e-mail adresses to match these new addresses" Press OK

Now all your user account have the new e-mail adress
If u want make this new adress primary just take "Set as primary" and press "OK"



Technically speaking you do not require to do anything Recipient Update Service should do the trick for you. Yes, what you need to do is to Apply the Recipient Policy (by right clicking and selecting Apply this policy from ESM). Once done please update domain wide RUS. That should do the trick for you.

Ah yes please wait for atleast 15mins before you press the panic button :)
