At a glance

First prepare in your mail service, then connect in CONNECT AI. Follow the steps in order.

  1. In Daou OfficeStep 1: Check with your admin that access for other programs is on
  2. In CONNECT AIStep 2: Open the connection screen
  3. In CONNECT AIStep 3: Fill in the fields
  4. In CONNECT AIStep 4: Test the connection and save
In Daou Office

Step 1: Check with your admin that access for other programs is on

In Daou Office, the company admin turns IMAP and outgoing authentication (SMTP AUTH) on or off for each mail group. Companies set up on or after September 8, 2026 start with them off. While they are off, the connection fails even with the right password.

  1. Ask your company’s Daou Office admin to check that IMAP and SMTP AUTH are on for the mail group your account belongs to.

  2. The admin can change this under 통합설정 (Integrated settings), App 관리 (App management), 임직원포털 (Employee portal), 메일 (Mail), 메일 그룹 (Mail groups).

Good to know

  • Since the Daou Office 4.0 upgrade on February 15, 2026, the incoming mail server is imap.daouoffice.com. If you saved your company’s own address before, switch to the new one.

Step 4: Test the connection and save

  1. Click Test connection at the bottom of the screen.

  2. Check that both of the results below appear.

Incoming serverIncoming connection succeeded
Outgoing serverOutgoing connection succeeded
Test connectionSave and finish
Example drawing · the real screen may look slightly different

  1. If both succeed, click Save and finish. If either one fails, this button stays disabled — see “If it won’t connect” below.

  2. You’re done when Email accounts in Settings shows Connection normal.

That’s it — you’re connected

After connecting

  • Email you send from CONNECT AI goes out from this Daou Office address.
  • Buyer replies are fetched every 5 minutes. If a reply doesn’t show up right away, give it a little time.
  • Your mail stays in your Daou Office mailbox. CONNECT AI never edits or deletes it.
  • Changing any field clears the test results. After a change, click Test connection again.

If it won’t connect

When a test fails, the screen tells you why. Find the message below.

If you see this

Authentication failed

What to do
  1. Check that the email address is complete, including everything after @, not just the ID.
  2. Check that the password is the one you normally use to sign in to Daou Office.
  3. If receiving works but sending fails, SMTP AUTH is most likely off on the admin side. Ask your admin as in step 1.
  4. If it still fails, your company may restrict IP addresses. See “Still failing with the right password?” below.
If you see this

Connection test failed for an unknown reason

What to do
  1. Check that you entered the Daou Office sign-in password.
  2. Check that you finished the steps in Daou Office (from step 1).
  3. If both are right, your company may block other programs from connecting. See “Still failing with the right password?” below.
  4. If it still fails, take a screenshot and send it to our support team below.
If you see this

The server didn't respond Couldn't reach the server

What to do
  1. Check the server address and port again. The ports are 993 for incoming and 465 for outgoing.
  2. Make sure there are no extra spaces or missing letters in the addresses.
If you see this

TLS negotiation failed

What to do

Check the security setting again: SSL/TLS for the incoming server and SSL for the outgoing server.

If you see this

Your mail service is blocking connections from the CONNECT AI server's IP address

What to do

Your mail service is blocking the CONNECT AI server. See “Still failing with the right password?” below.

If you see this

Form values changed during the test

What to do

You changed a field while the test was running. Click Test connection again.

If you see this

The Test connection button is disabled

What to do

Fill in every field: the full email address (including everything after @), the password and its confirmation, the incoming and outgoing server addresses, and the ports (numbers only). Also check that both password fields match.

If you see this

The Save and finish button is disabled

What to do

Both the incoming and the outgoing test must succeed. Find the message from the side that failed in this list.

Still failing with the right password?

Daou Office lets your company admin block other programs from reaching mail. When that happens, the screen may say “Authentication failed” even though the password is right.

  • Confirm again that the admin has turned on IMAP and SMTP AUTH in the mail group settings.
  • If the admin allows sign-ins only from company IP addresses (보안관리 (Security management) › 로그인 차단 설정 (Login block settings)), the CONNECT AI server may be blocked. Ask our support team for the server IP.

Leave your domain settings alone

Google Workspace and MX records

  • You do not need to change your domain settings to connect mail. You do not need Google Workspace either.
  • If you change your domain’s MX records or add another provider’s (such as Google’s), mail to your company goes there first. Mail for staff who have no account there can bounce.
  • If you have already changed them, remove only the line you added and keep your original mail service’s lines.
