# Email Authorization

> Before you connect a customer service mailbox in Niceggie, you need to complete authorization on the mail provider's side — either an OAuth sign-in or an authorization code. This page walks through the 10 supported mail providers below; use the table to jump straight to the section you need.

!!! scope "Who can use this"
    - **Who needs it**: Amazon, Newegg and Walmart stores, whose buyer messages arrive through a bound support mailbox. eBay, Best Buy and TikTok Shop don't need one
    - **Providers**: 10, including Outlook, Hotmail, Gmail / Google Workspace, QQ Mail and Zoho Mail
    - **Before you start**: access to the mailbox account, to sign in (OAuth) or to generate an authorization code / app password

## Overview

🔐 = **OAuth authorization** (sign in to your Microsoft/Google account when prompted — no code to generate in advance)
🔑 = **Authorization code / App Password** (generate this on the provider's side first, then paste it into Niceggie's Connect Your Email page)

| Provider | Authorization method | Jump to |
|---|---|---|
| Outlook | 🔐 OAuth | [View guide](#outlookcom) |
| Hotmail | 🔐 OAuth | [View guide](#hotmailcom) |
| Gmail / Google Workspace | 🔑 App Password | [View guide](#gmailcom) |
| QQ Mail | 🔑 Authorization Code | [View guide](#qqcom) |
| 126 / 163 Mail (incl. NetEase Enterprise Mail) | 🔑 Authorization Code | [View guide](#126com163com) |
| Tencent Enterprise Mail | 🔑 Authorization Code | [View guide](#tencentbusinessmail) |
| Aliyun Mail (Personal / Enterprise) | 🔑 Authorization Code | [View guide](#aliyunbusinessmail) |
| Feishu Mail | 🔑 Authorization Code | [View guide](#feishubusinessmail) |
| Zoho Mail | 🔑 App Password | [View guide](#zohobusinessmail) |
| 263 Enterprise Mail | 🔑 Authorization Code | [View guide](#263businessmail) |

!!! info "Which channels need a mailbox?"
    Amazon, Newegg and Walmart buyer messages reach AI Customer Service through a bound customer mailbox, so those stores need a mailbox here. eBay, Best Buy and TikTok Shop sync buyer messages automatically after store authorization and do not need a separate mailbox binding. While binding, you can pick which authorized stores the mailbox syncs messages for (multi-select; you can change this later under **User Center → Authorization → Customer mailbox**).

## Outlook { #outlookcom }

**Authorization method:** 🔐 OAuth. **No code needed in advance** — on Niceggie's Connect Your Email page, choose Outlook and follow the on-screen prompts to sign in to your Microsoft account.

=== "Business users"

    1. Contact your IT administrator to confirm IMAP & SMTP access is enabled for this mailbox.
    2. On Niceggie's Connect Your Email page, choose **Outlook**, enter your email account, and click **Authorize**.
    3. You'll be redirected to the Microsoft sign-in page. Enter your email account and password to log in.
    4. Microsoft will show a consent prompt asking whether to allow Niceggie to access your mailbox. Click **Accept**.
    5. Back on Niceggie's Connect Your Email page, choose the folders you want to authorize, finish the setup, and save.

    1. Sign in to the web version of your Outlook account (if you use the Outlook desktop client, the path to enable IMAP may differ from the steps below).
    2. Click the **Settings** button (gear icon) in the top-right corner, then select **Mail**.
    3. On the settings page, find **Forwarding and IMAP**.
    4. Complete identity verification as prompted, then find **POP and IMAP** and turn on **Allow devices and apps to use POP and IMAP**.

![Microsoft OAuth consent prompt asking you to click Accept to let Niceggie access your mailbox](https://www.niceggie.com/helpcenter/en/assets/images/screenshots/email-auth/outlook-oauth-consent.webp)

!!! tip "Consent window not showing up?"
    Check whether your browser blocked the pop-up, or sign out of your mailbox and back in once before trying to authorize again.

| Protocol | Host | Port | Encryption |
|---|---|---|---|
| IMAP | outlook.office365.com | 993 | SSL |
| SMTP | smtp.office365.com | 587 | TLS |

!!! info "Server details are for reference only"
    OAuth authorization negotiates the connection automatically — you generally don't need to enter the server addresses manually.

## Hotmail { #hotmailcom }

**Authorization method:** 🔐 OAuth. **No code needed in advance** — the process is identical to Outlook.

!!! info "Hotmail is now Outlook"
    Hotmail has been fully rebranded as Outlook. Your email address (e.g., `xxx@hotmail.com`) still works, and all mail, contacts, and other data have already been migrated to the Outlook service.

    2. On Niceggie's Connect Your Email page, choose **Hotmail**, enter your email account, and click **Authorize**.

1. Sign in to your Gmail account.
2. Click **Settings** (gear icon) in the top-right corner, then **See all settings**.
3. On the **Forwarding and POP/IMAP** tab, set **IMAP access** to **Enable IMAP** and save changes (this step doesn't generate an authorization code).
4. Click your account avatar in the top-right corner and select **Manage your Google Account**.
5. In the left menu, select **Security** → **2-Step Verification**. If it isn't enabled yet, follow the prompts to turn it on (you may need to verify your identity).

![Gmail App Password flow: enable IMAP → turn on 2-Step Verification → open App Passwords and enter a custom app name](https://www.niceggie.com/helpcenter/en/assets/images/screenshots/email-auth/gmail-app-password.gif)

!!! warning "2-Step Verification is required first"
    Your Google account must have 2-Step Verification turned on before the **App Passwords** option appears; it stays hidden otherwise.

!!! tip "Google Workspace works the same way"
    Google Workspace (business) mailboxes follow the same authorization steps as personal Gmail. If your account is centrally managed and 2-Step Verification or App Passwords aren't available, ask your administrator to enable them first.

| IMAP | imap.qq.com | 993 | SSL |
| SMTP | smtp.qq.com | 465 | SSL |

![Setting the IMAP service to Trust after a 126/163 security check](https://www.niceggie.com/helpcenter/en/assets/images/screenshots/email-auth/126-trust.gif)

!!! tip "The Trust step improves connection stability"
    After a personal mailbox passes the **Security Level** check and you set the IMAP service to **Trust**, you'll see fewer re-verification prompts during later sync.

## Tencent Enterprise Mail { #tencentbusinessmail }

**Authorization method:** 🔑 Authorization Code. By default this is your mailbox login password; if **secure login** is enabled, you'll need to generate a separate client-specific authorization code instead.

1. Contact your mailbox administrator to confirm POP3/IMAP/SMTP access is enabled for this mailbox.
2. Sign in to the Tencent Enterprise Mail web client, click **Settings** → **Mail Sending and Receiving Settings**, and confirm **Client Service Agreement** is enabled.
3. If **secure login is not enabled**: the authorization code is simply your mailbox login password — use it directly.
4. If **secure login is enabled**: go to **Settings** → **Mailbox Binding** and generate a client-specific authorization code.
5. Paste the code (your login password or the client-specific code) into the authorization code field on Niceggie's Connect Your Email page, choose the folders you want to authorize, and save.

!!! tip "Not sure whether secure login is enabled?"
    Check the current login-protection status under Tencent Enterprise Mail's **Settings** → **Security Settings**; contact your mailbox administrator if you're unsure.

| Protocol | Host | Port | Encryption |
|---|---|---|---|
| IMAP | imap.exmail.qq.com | 993 | SSL |
| SMTP | smtp.exmail.qq.com | 465 | SSL |

## Aliyun Mail (Personal / Enterprise) { #aliyunbusinessmail }

**Authorization method:** 🔑 Authorization Code (Aliyun Mail calls this a "third-party client security password"). Aliyun Mail blocks third-party client sign-in by default, so you first need to confirm the relevant permission is enabled, then generate a security password to use as the authorization code. Personal and enterprise mailboxes sign in through different portals — pick the matching tab below.

=== "Personal mail (aliyun.com)"

    1. Confirm your account isn't restricted from third-party client sign-in by your mailbox administrator, and that IMAP or POP3 access is enabled (contact your administrator if you're unsure).
    2. Sign in to the web version of Aliyun Mail (mail.aliyun.com), then click **Settings** → **Account and Security**.
    3. Find **Third-Party Client Security Password**, click **Generate Password**, and complete identity verification as prompted (e.g., SMS code).
    4. Copy the generated security password and paste it into the authorization code field on Niceggie's Connect Your Email page, choose the folders you want to authorize, and save.

    | Protocol | Host | Port | Encryption |
    |---|---|---|---|
    | IMAP | imap.aliyun.com | 993 | SSL |
    | SMTP | smtp.aliyun.com | 465 | TLS |

=== "Enterprise mail (qiye.aliyun.com)"

    1. Contact your enterprise mailbox administrator to enable IMAP or POP3 access for this account in the admin console, and allow third-party client sign-in.
    2. Sign in to the web version of Aliyun Enterprise Mail (qiye.aliyun.com), then click **Settings** → **Account and Security**.
    3. Find **Third-Party Client Security Password**, click **Generate Password**, and complete identity verification as prompted.
    4. Copy the generated security password and paste it into the authorization code field on Niceggie's Connect Your Email page, choose the folders you want to authorize, and save.

    | Protocol | Host | Port | Encryption |
    |---|---|---|---|
    | IMAP | imap.qiye.aliyun.com | 993 | SSL |
    | SMTP | smtp.qiye.aliyun.com | 465 | TLS |

!!! warning "The security password is not your mailbox login password"
    Once the third-party client security password feature is enabled, third-party clients must use the generated security password — entering your regular mailbox login password will fail with a "wrong username or password" error.

## Feishu Mail { #feishubusinessmail }

**Authorization method:** 🔑 Authorization Code (Feishu Mail calls this a "third-party client password").

1. Contact your enterprise administrator to enable **Allow employees to sign in to Feishu Mail with a third-party email client** in the Feishu admin console (skip this step if it's already enabled).
2. Sign in to the web version of Feishu Mail, then click **Settings** → **Account and Security**.
3. Find **Third-Party Client Password**, click **Generate Password**, and complete identity verification as prompted.
4. Copy the generated authorization code and paste it into the authorization code field on Niceggie's Connect Your Email page, choose the folders you want to authorize, and save.

!!! info "This option is hidden until an administrator enables it"
    The **Third-Party Client Password** feature must be turned on by an administrator first — employees can't enable this permission themselves from their personal settings.

| Protocol | Host | Port | Encryption |
|---|---|---|---|
| IMAP | imap.feishu.cn | 993 | SSL |
| SMTP | smtp.feishu.cn | 465 | SSL |

## Zoho Mail { #zohobusinessmail }

**Authorization method:** 🔑 App Password. Your sign-in domain is either `pro.zoho.com` (Professional) or `zoho.com` (Standard), depending on your account — the steps are the same either way.

1. Sign in to your Zoho Mail account.
2. Click **Settings** (gear icon) in the top-right corner.
3. In the left menu, select **Email Accounts**, then check every sub-option under IMAP and SMTP and save.
4. Back on the mail list page, click your avatar in the top-right corner and select **My Account**.
5. Go to **Security** → **App Passwords** → **Generate New Password**. In the dialog that opens, type a name of your choice (e.g., Niceggie) in the name field and click **Generate**.
