Setting Up Your Email on Desktop and Mobile Devices After the Email Migration

Need help setting up your email on your computer, phone, or tablet? Follow this guide to connect your Cybernautic email account after your mailbox has been migrated.

Before You Begin

Before setting up your email application, make sure you have the following:

  • Your complete email address.
  • Your current email password.
  • Confirmation from Cybernautic that your email migration is complete.
Important: Please wait for Cybernautic to confirm that your email migration is complete before changing your email application settings. These instructions are for your new mailbox configuration. We will notify you when your mailbox is ready for setup.

We also recommend changing your temporary password before configuring your email. If you need help, refer to our How to Change or Reset Your Email Password article.

Before Removing or Reconfiguring Your Existing Account

Depending on your email application, you may need to remove your existing account and add it again using the new server settings. Before doing so, please take a moment to check the following:

  • Make sure your important messages and folders are visible in Cybernautic Webmail.
  • Check whether you have locally stored messages, folders, contacts, or calendar items that may not be synchronized with the mail server.
  • If you use Microsoft Outlook, check whether you have folders marked This Computer Only.
  • Save a copy of your existing email signature and take note of any custom rules or settings you may need to recreate.

For detailed instructions on backing up your email data, refer to our How to Back Up Your Email Data Before Reconfiguring Your Email Account article.

Important: Do not remove your existing email account until you have confirmed that your mailbox migration is complete and that any important locally stored data has been backed up. If you are unsure whether your messages are synchronized, contact Cybernautic Support before proceeding.

Email Server Settings

Use the following settings when manually configuring your email application.

Incoming Mail Settings (IMAP)

1. Microsoft Outlook for Windows

Depending on your Outlook version, you may be able to update the existing account's server settings without removing the account. If this option is unavailable, you can add the new account instead.

Option B: Add a New IMAP Account

  1. Open Microsoft Outlook.
  2. Go to File → Add Account.
  3. Enter your complete email address.
  4. If available, select Advanced options → Let me set up my account manually, then click Connect.
  5. Select IMAP.
  6. Enter the incoming mail settings:
    • Server: mail.cybernautic.com

  8. Enter your complete email address as the username and your current email password. Make sure outgoing server authentication is enabled.
  9. Complete the setup and allow Outlook to verify the connection.

Depending on your Outlook version, you may be able to update the existing IMAP account's server settings instead of removing and adding the account again.

Option A: Update the Existing Account

  1. Open Microsoft Outlook.
  2. Select Outlook → Settings.
  3. Select Accounts.
  4. Choose your existing email account.
  5. Look for the Server Information section.
  6. If available, click Configure.

  8. Update your password if required.
  9. Save the changes and allow Outlook to reconnect.

Note: Some older Outlook for Mac versions use a different menu layout. You may find account settings under Tools → Accounts. If the Configure option is unavailable, you may need to add a new account.

Option B: Add a New IMAP Account

  1. Open Microsoft Outlook.
  2. Go to Outlook → Settings → Accounts.
  3. Choose the option to add an email account.
  4. Enter your complete email address.
  5. If prompted, select Not an Exchange account or a similarly worded option.

  7. If Outlook displays an additional option such as Sync with IMAP, select it to continue.
  8. Enter the incoming and outgoing server settings listed in the Email Server Settings section above.
  9. Enter your complete email address and current password for authentication. Ensure that outgoing server authentication is enabled.
  10. Save the settings and allow Outlook to complete the setup.
  11. Send a test email and confirm that incoming messages are received.
Important for Outlook for Mac users: Outlook may initially assume that your email account is a Microsoft Exchange account. Make sure you select the option to continue with IMAP instead.

If you add a new account, keep the old account until the new mailbox has synchronized and you have checked your messages and folders.

3. Mozilla Thunderbird

Before removing or recreating your account, check whether you have important messages stored under Local Folders. These folders may not be synchronized with the email server.

  4. Enter your name, complete email address, and password.
  5. If automatic configuration does not detect the correct settings, select Configure manually.

Incoming Mail Settings

  • Protocol: IMAP
  • Server: mail.cybernautic.com
  • Port: 993
  • Connection security: SSL
  • Authentication: Normal Password
  • Username: Your complete email address

Outgoing Mail Settings (SMTP)

  • Server: mail.cybernautic.com
  • Port: 465

  • Authentication: Normal Password
  • Username: Your complete email address
  1. Click Done to save the settings.

4. Apple Mail on Mac

  1. Open Apple Mail.
  2. Select Mail → Add Account.
  3. Choose Other Mail Account and click Continue.
  4. Enter your name, email address, and password.
  5. Click Sign In.
  6. If automatic configuration fails, select IMAP and manually enter the incoming and outgoing server settings listed in the Email Server Settings section above.
  7. Ensure that outgoing SMTP uses port 465, SSL, and authentication with your complete email address and current password.
  8. Save the settings.
  9. Send a test email and confirm that incoming messages appear in your Inbox.

If you need to remove the old account before adding the new one, first make sure that any messages you want to keep are synchronized with the server or backed up separately.

5. Apple Mail on iPhone or iPad

If your existing email account was configured using the old mail server, simply changing the incoming server settings may not be enough.

iOS may lock fundamental account settings, such as the account protocol (IMAP or POP) and incoming server hostname, after the account has been initially verified. If you cannot successfully update the incoming server settings, you may need to remove the old account and add it again.

Before Removing the Existing Account

  • Confirm that Cybernautic has completed your mailbox migration.
  • Make sure you have your current email password.
  • Check that your important messages and folders are visible in Cybernautic Webmail.
  • If you have messages that are not visible in Webmail, contact Cybernautic Support before removing the account.
Important: Removing an IMAP account from your iPhone or iPad removes the account connection and its synchronized local cache. It does not delete the mailbox stored on the email server. However, messages that have not synchronized with the server may not be available after the account is removed. Check your mailbox in Webmail first.

Remove the Old Account and Add the New One

  1. Open Settings.
  2. Navigate to Apps → Mail → Mail Accounts on newer iOS versions, or Mail → Accounts on older versions.
  3. Select your existing email account.
  4. Tap Delete Account or Remove Account, depending on your iOS version.
  5. Return to Mail Accounts and select Add Account.
  6. Choose Other → Add Mail Account.
  7. Enter your name, complete email address, password, and an account description.
  8. Tap Next.
  9. Select IMAP.

Incoming Mail Server

  • Host Name: mail.cybernautic.com
  • Username: Your complete email address
  • Password: Your current email password

Outgoing Mail Server

  • Host Name: mail.cybernautic.com
  • Username: Your complete email address
  • Password: Your current email password
  1. Tap Next and allow your device to verify the settings.
  2. Save the account.
  3. Allow your device to synchronize.
  4. Send a test email and confirm that you can receive messages.
iPhone and iPad users: If additional outgoing server settings appear, ensure that SMTP authentication is enabled and that port 465 with SSL is selected. Enter your complete email address and current password for outgoing mail authentication.

Troubleshooting Common Email Setup Problems

I cannot sign in to my email account.

  • Check that you entered your complete email address as the username.
  • Verify that your password is correct.
  • Confirm that Cybernautic has completed your mailbox migration.
  • If you recently changed your password, update the saved password in your email application.
  • Try signing in through Cybernautic Webmail to check whether your credentials work.

I can receive emails but cannot send them.

  • Confirm that the outgoing server is mail.cybernautic.com.
  • Verify that the outgoing port is 465.
  • Ensure that SSL encryption is enabled.
  • Confirm that SMTP authentication is enabled.
  • Use your complete email address and current password to authenticate.

My email application keeps asking for my password.

  • Check for typing errors in your email address and password.
  • Remove any outdated saved password and enter your current password again, if your application requires it.
  • Verify that both incoming and outgoing servers use the correct credentials.
  • If you recently changed your password, make sure you updated it on all your devices.

My email application displays a connection or security warning.

  • Double-check the server name, port, and encryption settings.
  • Confirm that your device has a working internet connection.
  • Do not bypass certificate warnings without verifying the server and certificate with Cybernautic Support.

My old email messages or folders are missing.

Confirm that your mailbox migration is complete and that you are connecting to the correct account. Allow time for your email application to synchronize with the server.

Sign in through Cybernautic Webmail and check whether the missing messages or folders are visible there. If they remain missing after synchronization, contact Cybernautic Support for assistance.

I cannot change the incoming mail server on my iPhone or iPad.

  • iOS may not allow fundamental account settings, such as the incoming server hostname or account protocol, to be changed after the account has been created and verified.
  • If the old server settings remain in place or the account will not connect after editing, remove the old email account from your device.
  • After confirming that the migration is complete, add the account again using the Apple Mail on iPhone or iPad instructions above.
  • Before removing the account, confirm that any messages you need to keep are synchronized with the mail server.

Outlook for Mac keeps trying to set up my account as Exchange.

  • When adding the account, look for an option such as Not an Exchange account and select it.
  • Choose IMAP as the account type.
  • If prompted, select Sync with IMAP to continue with IMAP configuration.
  • Enter the incoming and outgoing server settings listed in this guide.

The exact labels and setup screens may vary depending on your Outlook version.

My Outlook signature or settings are missing after the migration.

Some Outlook settings are stored separately from your email messages and may not be included in a PST or OLM backup. You may need to recreate your email signature, message rules, and blocked or safe sender lists.
