You have a Microsoft Exchange Server 2019 organization that contains 200 mailboxes.
You need to add a second email address to each mailbox. The address must have a syntax that uses the first letter of each user's last name, followed by the user's first name, and then @fabrikam.com.
Solution: You convert all the mailboxes to shared mailboxes, and then you run the
Set-Mailbox cmdlet and specify the -EmailAddressPolicyEnabled $false parameter.
Does this meet the goal?
Answer

Suggested Answer

The suggested answer is B.

The solution proposed does not meet the goal. Converting mailboxes to shared mailboxes and setting the EmailAddressPolicyEnabled parameter to $false does not achieve the goal of adding a second email address with the specified format. Instead, you need to use an email address policy or script to correctly format and add the new address. The EmailAddressPolicyEnabled parameter, when set to $false, ensures that email address policies are not applied, but it does not help in creating new addresses as required by the scenario.

You need to add a second email address to each mailbox. The address must have a syntax that uses the first letter of each user's last name, followed by the user's first name, and then @fabrikam.com.
Solution: You create an email address policy that uses the %1s%g@fabrikam.com email address format.
Does this meet the goal?
Answer

Suggested Answer

The suggested answer is B.

The provided solution does not meet the goal because creating a new email address policy is not necessary when you need to add a second email address to existing mailboxes. Instead, the existing policy should be modified to include the secondary email address. Each mailbox can only have one email address policy applied to it, so creating an additional policy would not achieve the desired result.

Solution: You convert all the mailboxes to shared mailboxes, and then you run the
Set-Mailbox cmdlet and specify the -EmailAddressPolicyEnabled $true parameter.
Does this meet the goal?
Answer

Suggested Answer

The suggested answer is B.

Converting all the mailboxes to shared mailboxes is unnecessary to add a second email address. Shared mailboxes are typically used for scenarios where multiple users need access to the same mailbox, and converting user mailboxes to shared mailboxes does not address the primary goal of adding a second email address with a specific syntax. Additionally, the command Set-Mailbox with the parameter -EmailAddressPolicyEnabled $true merely enables email address policies but does not itself create or enforce any specific email address format. Therefore, the solution provided does not meet the requirement of adding a second email address in the specified format.
