Set up an email account

The wizard locates the appropriate settings. You provide credentials only after verification.

Add an account

  1. Open File → Info → Add Account.
  2. Enter your email address and continue.
  3. Verify the provider, account type and detected servers. Use manual setup if your provider is not recognized.
  4. Complete the sign-in. Afterwards netMail downloads folders and messages in the background.

While netMail searches for the provider or verifies the connection, the account wizard displays a loading indicator. It signals that the setup is still running. Wait for the result before proceeding. When the process completes or an error occurs, the animation stops and the next step or a notification is shown.

IMAP and SMTP

IMAP keeps received messages and folders synchronized with the mail server. SMTP is responsible for sending. Your provider specifies server names, ports and the secure connection. Some providers require IMAP to be enabled first or a dedicated app password to be created.

Username and e-mail address can be different. The username for sending may also differ from the username for receiving; in that case enter both values separately.

Microsoft 365 and Exchange

For Microsoft 365 and Exchange Online select Sign in with Microsoft in the wizard. Sign in in the browser window that opens and confirm access. After that netMail will configure the new account automatically. If you cancel, your inputs are retained without creating the account.

The success message in the browser confirms the Microsoft sign-in. Then wait until netMail confirms the account setup. If an error appears there, read the full message and restart the sign-in in the account wizard.

Keep the sign-in window in netMail open during the browser sign-in. If an error occurs, read the provider’s full message in netMail, close the window and start the sign-in in the account wizard again. An old browser tab is no longer associated with a new sign-in attempt.

Specific requirements from your organization are accessed via Advanced settings. If browser sign-in is not yet enabled or your organization must approve access first, contact support or your administration. For a self-hosted Exchange server the wizard can determine the address via automatic server discovery.

Shared mailboxes and calendars appear where the server provides them and your account is authorized for them. Read-only sharing does not permit changes. Additional accounts, Microsoft 365 and Exchange depend on your Pro or trial license level.

After setup

Let the initial synchronization complete. Use Send/Receive to start another retrieval. If an error occurs, do not change multiple values on a hunch: first check the sign-in, server address and the information from your provider.
