- Product
- Microsoft 365 / Outlook
- Device & OS
- not provided
- Scenario
- Sending bulk emails or corporate announcements where sender privacy, security, or generic branding is required.
- Observed behavior
- The user needs a method to configure their email setup to mask their personal address and display a group, shared, or alternate email address instead.
Ensure you have an active Microsoft 365 account and know who your IT administrator is, as you will need admin privileges to configure specific mailbox permissions.
Use Microsoft 365 'Send As' or 'Send on Behalf' Permissions
Configure your Microsoft 365 account to send emails using a shared mailbox or group address instead of your personal email.
'Send As' makes the email appear to come directly from the group address, keeping your personal identity completely hidden. 'Send on Behalf' shows that you are sending the message on behalf of the group, which still displays your name alongside the group address. Both methods require administrative permissions to set up.
Contact your Microsoft 365 Administrator to request 'Send As' or 'Send on Behalf' permissions for the desired group or shared mailbox.
Once permissions are granted, open Outlook and start composing a new email. Click on the 'Options' tab in the ribbon and select 'From' to display the From field in your message header.
Click the 'From' dropdown button next to your email address, select 'Other Email Address', and type in the group or shared mailbox address.
Compose your message, add your large group of recipients to the 'To' or 'Bcc' field, and click Send. The recipients will only see the group address as the sender.
Use a Third-Party Email Marketing Service
Utilize an external email marketing platform to send bulk emails while protecting your personal address and ensuring high deliverability.

Frequently Asked Questions
Can I use BCC to hide my personal email address?
Using BCC (Blind Carbon Copy) hides the recipients' addresses from each other, but your personal email address will still appear in the 'From' field. To hide your own address from the recipients, you must use a shared mailbox, an alias, or a third-party service.
What is the difference between an email alias and a shared mailbox?
An alias is an additional email address tied directly to your primary personal account. A shared mailbox is a separate, dedicated mailbox that multiple authorized users can access and send emails from using 'Send As' permissions.
Will sending emails to a very large group from my personal account mark me as spam?
Yes, sending a single email to hundreds of recipients using a standard personal or business email account can trigger ISP spam filters and lead to your account being temporarily blocked. Using an email marketing service is highly recommended for bulk communications.
