How to configure a Send-Only account in Outlook
You want to create a Send-Only email account (from which mail is never downloaded) in Outlook.
To exclude an email account from receiving emails in Outlook, you need to add this account as a new POP3 account in Outlook. Then you need to modify this account by setting a fake (non-existent) incoming mail server.
Follow the steps below to add a Send-Only account in Outlook 2016:
- (Optional) Before you add a new email account, you might want to prevent Outlook from importing this account's emails. To do so, you need to temporarily disable the automatic send/receive capability in Outlook for all of your accounts. Go to the Send / Receive tab, click Send/Receive Groups, and select Disable Scheduled Send/Receive, as shown in Fig. 1.
- To add a new account in Outlook, go to File > Add Account.
- Type the address of your account. Click on Advanced options and select Let me set up my account manually (Fig. 2.), then click Connect.
- Choose POP as the account type (Fig. 3.).
- Configure incoming and outgoing mail server settings for your account (see an example in Fig. 4.). Make sure to provide valid information. Otherwise, Outlook will refuse to add this account. Click Next to add the account.
See this Microsoft article to get POP settings for common email providers.
- Type the password for your account and click Connect. Outlook will test the connection. When the account setup is complete, click OK.
- Your email account is now visible in Outlook.
- If you followed Step 1 and temporarily disabled the scheduled Send/Receive tasks in Outlook, the mailbox does not contain any emails. This is only temporary - once you resume the send/receive tasks, the mailbox will receive messages in the usual way. To avoid this, proceed to Step 8.
- If you skipped Step 1, you will have access to all emails in this mailbox once Outlook downloads them. You will also receive new emails sent to this account.
- To stop Outlook from receiving emails for the account you added, you need to modify the settings of the incoming mail server for this account: open the File tab in Outlook and go to Account Settings (Fig. 5.).
- On the Email tab, edit your email account by double-clicking it or via the Change button (Fig. 6.).
- The server settings window opens. Change the name of the Incoming mail server to any fake name (e.g. fake-server) and clear the Automatically test account settings when Next is clicked checkbox (Fig. 7.). Click Next and then Finish.
- This email account has now become a Send-Only account. You can use it to send emails, but Outlook will not receive emails sent to this account.
- Optional steps:
- If you disabled the send/receive tasks in Outlook (Step 1), turn it back on to resume your mail flow.
- If you skipped Step 1 and you would like to remove the existing content of your send-only mailbox account (e.g. emails automatically downloaded by Outlook when you added this account), you can clear this data on the Data Files tab in the Account Settings (see Fig. 6.).
Since you provided a fake name of the incoming mail server, Outlook displays a Send/Receive error (Fig. 8.) for your Send-Only account each time a send/receive task is performed. You can ignore this error notification - other email accounts are not affected.
