Reply to a different email address.

Hi Aji_Cherian,

for your idea you can try to use email forwarding for operator mailboxes in Exchange Admin Center.

You can also redirect all messages in Outlook on the Web.
Use rules to automatically forward messages - Microsoft Support

Messages that are redirected will appear to come from the original sender.
When you reply to a message that has been redirected, the reply will be sent to the original sender.

1. In Outlook Web App, click Settings 

    

    > Options > Organize Email > Inbox Rules.

2. On the Inbox rules tab, click the arrow next to the plus symbol +, and select Create a new rule for arriving messages.

3. Under When the message arrives, select Apply to all messages.

4. Under Do the following, select Redirect the message to.

5. Select the address you want your mail sent to by double-clicking it in the address book view. If the address you want to redirect to isn’t in the address book, you can enter the email address in the To line at the top of the window.

6. Click OK to save your selections and return to the new rule window.

7. Click Save to save your rule and return to the Inbox rules tab.

It's important to note that this will forward all incoming emails to the specified common email address, not just replies from customers.

For that you can create a specific rule in Exchange Admin Center:
- click on Mail Flow > Rules
- Click on Add a Rule

- In the Apply this rule if choose The recipient

- In the dropdown list you can choose only one recepient and do a same separate rule for every operator or you can previously create a group containing your operators and then choose this group.

- you can add additional filters to better define which emails should be redirected to you common email adress.
