Set default from address based on To address in Exchange Office 365

When using Exchange Office 365, it is important to set the default "From" address based on the "To" address. This ensures that your emails are sent from the correct email address, depending on who you are sending the email to. This can be especially useful if you have multiple email addresses associated with your account.

To set the default "From" address based on the "To" address in Exchange Office 365, follow these simple steps:

1. Log in to your Exchange Office 365 account.
2. Click on the gear icon in the top right corner to access the settings menu.
3. From the settings menu, select "Options".
4. In the left-hand menu, click on "Mail".
5. Under the "Mail" section, click on "Message handling".
6. Scroll down to the "Send messages" section and click on "Always reply from default address".
7. Next, click on "Add" to add a new rule.
8. In the "Apply this rule if" dropdown menu, select "The recipient is".
9. In the "Select a recipient" dropdown menu, choose the email address you want to set as the default "From" address for specific recipients.
10. Click on "OK" to save the rule.
11. Repeat steps 7-10 for each email address you want to set as the default "From" address for specific recipients.
12. Click on "Save" to apply the changes.

By following these steps, you can ensure that your emails are sent from the appropriate email address based on who you are sending the email to. This can be particularly useful if you have different email addresses for personal and professional use, or if you manage multiple email accounts.

It is important to note that the steps may vary slightly depending on the version of Exchange Office 365 you are using. If you are unsure or need further assistance, it is recommended to consult the official Microsoft documentation or contact your IT support team.
