Outlook is one of the most widely used email programs in offices. This guide shows how to add your business mailbox to classic Outlook (part of Microsoft 365 and Office) and to the new Outlook for Windows — first with automatic setup, and manually if that doesn't work.
What you'll need
- Your full email address, for example
name@example.uz. This is also your username. - Your mailbox password. If you don't know it, ask your domain administrator to set a new one in the control panel.
- Server settings — needed only for manual setup:
| Setting | Value |
|---|---|
| Incoming mail server (IMAP) | mail.mcmail.uz |
| IMAP port, encryption | 993, SSL/TLS |
| Outgoing mail server (SMTP) | mail.mcmail.uz |
| SMTP port, encryption | 465, SSL/TLS |
| Alternative SMTP port | 587, STARTTLS |
| Username | your full email address |
We recommend IMAP: messages stay on the server and look the same in Outlook, on your phone, and in webmail. For the difference between IMAP and POP3, see IMAP, POP3, and SMTP.
If your administrator has turned on two-factor authentication for the mailbox, check with support on how to connect an email app: your regular mailbox password may not be enough.
Classic Outlook: automatic setup
MCMail supports automatic client configuration (Autodiscover), so in most cases Outlook finds the right servers on its own.
- Open Outlook. On first launch, the add-account wizard appears right away. Otherwise, go to File and click Add Account.
- Enter your full email address and click Connect.
- If Outlook asks for the account type, choose IMAP.
- Enter your mailbox password and click Connect again.
- When you see the success message, click Done.
Automatic setup only works if the domain's DNS records are configured correctly. If you get an error or Outlook suggests the wrong servers, switch to manual setup.
Classic Outlook: manual IMAP and SMTP setup
- In the add-account window, enter your email address, open Advanced options, and check the option to set up the account manually. Click Connect.
- Choose IMAP from the list of account types.
- Fill in incoming mail: server
mail.mcmail.uz, port993, encryption method SSL/TLS. - Fill in outgoing mail: server
mail.mcmail.uz, port465, encryption method SSL/TLS. - Leave Secure Password Authentication (SPA) unchecked.
- Click Next, enter your password, and click Connect.
If outgoing mail on port 465 doesn't go through (for example, your office network blocks it), try port 587 with STARTTLS encryption.
To change settings for an account you've already added, go to File → Account Settings. Depending on your version, you'll see either a server settings option or a list of accounts where you select the mailbox and click "Change."
New Outlook for Windows
The new Outlook is gradually replacing classic Outlook and the built-in Windows Mail app. The interface is different, but the steps are similar.
- Open Settings (the gear icon) → Accounts → Email accounts and click Add account.
- Enter your full email address and click Continue.
- If asked to pick a provider or account type, choose IMAP.
- Enter your password. If automatic setup fails, open the advanced settings and enter the servers manually, using the values from the table above.
- Confirm to add the account.
For mailboxes from third-party providers, the new Outlook uses Microsoft cloud sync: the connection to your mail server goes through Microsoft's servers. If that matters for your company's data policy, use classic Outlook or webmail instead.
Calendar and contacts
Over IMAP, Outlook syncs only email with the server. Calendar events and contacts you create in Outlook are stored locally on your computer and won't appear on your phone or in webmail.
If you need shared calendars and contacts on every device, the easiest option is to manage them in SOGo webmail at https://mail.mcmail.uz — see our SOGo webmail guide. On phones, calendar and contacts sync through Exchange ActiveSync or CalDAV/CardDAV. If you specifically want your calendar in Outlook, contact support and we'll walk you through the options for your version.
Common errors and fixes
| Symptom | What to check |
|---|---|
| Outlook keeps asking for the password | The username must be the full email address. Verify the password by signing in to webmail. After several failed attempts, brute-force protection may block sign-in temporarily — wait and try again |
| Mail comes in but won't send | SMTP server, port, and encryption method. Try the alternative port with STARTTLS |
| Certificate warning | The server name doesn't exactly match the one in this guide. Correct it instead of blindly accepting the certificate |
| Sent messages don't show up on your phone | Make sure you're using IMAP, not POP3, and that Outlook saves sent items to a folder on the server |
| Mail suddenly stops working for everyone | Check your balance: service is suspended when the balance reaches zero |
If an account in classic Outlook is misconfigured and you can't fix it, it's sometimes easier to create a new profile: Control Panel → Mail (Microsoft Outlook) → Show Profiles → Add. With IMAP, messages are stored on the server, so they'll download again after you set things up.
If the mailbox used to be connected via POP3 and messages were deleted from the server, they won't appear in the new profile — they exist only in the old Outlook data file (.pst). Don't delete that file until you're sure the messages have been moved.
If nothing helps, message support at @mycloudsupport with your Outlook version, mailbox address, and the error text (a screenshot works too).
