How to set up your business email in Outlook
Many businesses keep Outlook while changing where their email lives. Outlook works with any provider that offers IMAP, including GINbox: add the account once with the settings below, and your mail, folders and sent items stay in step with webmail and your phone.

The settings you will need
| Setting | Incoming mail (IMAP) | Outgoing mail (SMTP) |
|---|---|---|
| Server | mail.ginbox.net | mail.ginbox.net |
| Port | 993 | 465 (or 587) |
| Security | SSL/TLS | SSL/TLS on 465, STARTTLS on 587 |
| User name | Your full email address | Your full email address |
| Password | Your mail password, or an app password | The same as incoming |
| Sign-in required | Yes | Yes (“my outgoing server requires authentication”) |
If your mailbox has two-step sign-in, make an app password first (GINbox webmail → Settings → App passwords) and use it in place of your normal password.
Outlook for Windows (classic)
- Open Outlook and choose File → Add Account.
- Type your email address, open Advanced options, tick Let me set up my account manually, and choose Connect.
- Choose IMAP.
- Incoming mail: server
mail.ginbox.net, port993, encryption SSL/TLS. - Outgoing mail: server
mail.ginbox.net, port465, encryption SSL/TLS (or port587with STARTTLS). - Choose Next, enter your password, and Connect. Outlook downloads your folders.
The new Outlook for Windows, and Outlook for Mac
- New Outlook for Windows: Settings → Accounts → Add account, type your address, choose IMAP as the provider if asked, open the advanced settings and enter the same servers and ports. Microsoft syncs IMAP accounts in the new Outlook through its own cloud service; if adding the account fails there, classic Outlook connects directly.
- Outlook for Mac: Outlook → Settings → Accounts → + → New Account, type your address, choose IMAP/POP, then type IMAP and enter the incoming and outgoing servers above with SSL turned on.
Outlook on iPhone and Android
- In the Outlook app, open the menu and tap Add account → Add email account.
- Type your address; when Outlook offers a provider, choose IMAP (on some versions: “Change account provider” or “Set up account manually”).
- Turn on Advanced settings and enter
mail.ginbox.netfor both incoming (IMAP, 993) and outgoing (SMTP, 465) with your full address as the user name.

Questions people ask
Do I need a Microsoft 365 subscription to use Outlook with my business email?
No. Outlook can add any IMAP account. You need Outlook itself (bought, included with Microsoft 365, or the free mobile app), but your email can be with any provider.
Outlook keeps asking for my password. Why?
Usually the password is wrong or your mailbox has two-step sign-in. Make an app password in GINbox webmail (Settings → App passwords), name it “Outlook”, and enter it when Outlook asks.
Which is better in Outlook: IMAP or POP?
IMAP. It keeps mail on the server, so Outlook, your phone and webmail all match. POP downloads mail into Outlook’s file on one computer, and losing that computer can mean losing the mail.
Will my calendar appear in Outlook too?
No. An IMAP account carries mail only, and Outlook does not sync the standard CalDAV calendars by itself. Use the calendar in GINbox webmail, or add it to your phone’s own Calendar app from webmail Settings.
I see “The server could not be found” when sending.
Check the outgoing server name is mail.ginbox.net, the port is 465 with SSL/TLS (or 587 with STARTTLS), and that “My outgoing server requires authentication” is on.
