Step 2: Configure 2016 Outlook to use CruisersEmail on Windows

  1.       Outlook 2016 should already be installed on the computer
  2.       CruisersEmail should already be installed on the computer
  3.       CruisersEmail account should be active
Configure The Software:

Note: This step sets up Outlook to check for new incoming email, and send any new outgoing emails through the CruisersEmail app running on the same computer.   If you already use Outlook to check emails for your business accounts directly, it is advised to create a second Outlook Profile for CruisersEmail use so you can select regular email (or) CruisersEmail each time you launch Outlook, depending on whether you are on normal Internet or using limited connections (ie: satellite) on a passage or in remote locations.

1.) Find and Launch the traditional Windows Control Panel Mail Settings App

Open the search box from the Windows task bar, enter "Control Panel" and then click the Control Panel result.

In the search bar in the upper right of the Control Panel window, type "mail" and press enter to find the Mail settings app.

Launch the Mail settings app

2.) Create a new Outlook Profile for CruisersEmail

Click on "Show Profiles" to access the Profiles

Click "Add..." to create a new Profile.

Name the Profile something that indicates to you it's for CruisersEmail and click OK.

3.) Create a new Email Account setup in Outlook for CruisersEmail

Now we add an Email account to the Profile, use the Manual Setup option, click Next.

Select POP or IMAP, click Next.

Now we add the details for Outlook to communicate with the CruisersEmail app on your computer
  1. Enter your name so that others see it on emails you send
  2. Enter the custom domain email address provided by Sea-Tech, don't enter your CruisersEmail address here.  Note: Without performing this step, outgoing email sent from Outlook using CruisersEmail will have the From: address for your CruisersEmail account (ie: and recipients will see that email as the sender of the email, rather than your custom domain email address.
  1. Select POP3
  2. Incoming and Outgoing Mail Server = "localhost"
  3. Under Logon Information, Enter your CruisersEmail username and password, select remember password.\
  4. After filling out the fields, Click "More Settings ..."

In the General tab, your email address is all that is needed.

in the Outgoing Server tab, DESELECT "My outgoing server (SMTP) requires authentication"

In the Advanced tab, ensure that the incoming port is 110 and outgoing port is 25.
Do not select any encryption options.  Set the Server time out to the longest setting (10 minutes)
DESELECT "Leave a copy of messages on the server".  click OK

Back to the Add Account window, click Next and Outlook will test the connection.  As long as CruisersEmail is running, this test should complete successfully.

In the Mail window, change the setting to "Prompt for a profile to be used", then click OK

3.) Close and Relaunch Outlook to test.

Choose your new CruisersEmail profile when prompted

Set send/receive schedue to manual (this way you can control when Outlook and CruisersEmail sync's email.
Also, Disable Perform Send/Receive when Outlook starts

Finally, Test sending an email from Outlook to ensure that it appears to come from your primary email account.

Step 4: Configure Email Fetching in CruisersEmail/Xgate Client on Windows

Configure Fetching custom domain email to your CrusiersEmail computer (ie: myname@mycustomdomain)

  1. Steps 1 through 3 Complete and Tested
1.) Launch CruisersEmail or Xgate client software on your PC
2.) Open Remote Mail Access Window
      Options Menu -> Fetch Remote Mail Control...
3.) Click "Add"

4.) Select your cruisersemail username (should be already selected)
5.) Select IMAP-SSL (it will likely switch back to just IMAP later, but that's okay)
6.) Enter your custom email address provided by Sea-Tech
7.) Enter your email password provided by Sea-Tech
8.) Enter the server name exactly as entered in the above image ""
9.) Make sure the TCP port is set to 993 and SSL is checked.
10.) Click OK to Save, and click OK to close the Remote Mail Access window.

Now when CruisersEmail downloads email via satellite, it will request and download emails sent to your custom domain email address as well.

Step 5: Test the process

1.) Restart computer and login to windows
2.) Check Windows system tray to verify that CruisersEmail started automatically (mailbox icon)
3.) Launch Outlook and choose CruisersEmail profile on launch
4.) Click Send/Receive

CruisersEmail should initiate a connection to download new email and send any outgoing email in queue, then Outlook should load any received email into the Inbox when complete.

Testing and Troubleshooting

      mail from:
      mail to:
      reply to:
listed in the body of the response.   You can use this feature to ensure that your outgoing settings are correct.

Appendix: Managing Large Emails

By default CruisersEmail sets an email size limit of 50KB for incoming and outgoing email.   Any email that exceeds that size is queued and held.  This size limit is highly recommended for slow satellite connections such as Iridium Phone, Iridium Go, Inmarsat Phone, Redport Glow, Redport Aurora, and GlobalStar Phone connections.   You can adjust the size limits if desired, which you may want to do if you have a faster satellite connection and are not concerned about data consumption costs.

Large Incoming Emails
For incoming emails larger than the set limit, emails are sent to the BigMail queue in CruisersEmail.   A notification email is sent to you indicating that a large email was received, with the sender, subject, and size of the email.   If you decide you want to download the email anyway, you can reply to the notification email.  Next time CruisersEmail does a sync it will move the email out of Bigmail and download it to your Inbox like any other email.   If you ignore the notification, the email will stay in the BigMail queue for later.  You can choose to download it when you have a faster Internet connection such as Marina WiFi or cellular hotspot.

Dealing with multiple Large Emails at once
In the CruisersEmail app GUI you can also view the BigMail queue by clicking the BigMail button.  All large emails that have been put in the BigMail queue and not yet downloaded or deleted will be listed there.  You can select one or more messages and have them remotely deleted on the CruisersEmail server without downloading (Server Delete), or Downloaded on the next connection (Retrieve).   You can also "Drop from List" which removes the email from the BigMail list, but leaves it in the BigMail queue.   You can later resync the list if needed by clicking "Configure...", check the box for "Synchronize BigMail on server with local list" then clicking OK.   The list will resync on the next connection.

Sending Large Emails
If you need to send an email that is larger than your configured limit, you can do so by adding +bigmail to the end of the receipients email address.  This instructs CruisersEmail to ignore the size limit for that outgoing email.  You can also set a higher limit for outgoing messages if you want, while leaving a lower limit for incoming email.

Adjusting Incoming/Outgoing Size Limits
Within the CruisersEmail App, select the Filters menu, and select Configure...
      Check the box for "Set In Bound E-Mail Cutoff Size to"
            Select a new size from the dropdown.  (50KB is recommended for slow Iridium Go/Phone and Redport Glow connections)
      Check the box for "Set Out Bound E-Mail Cutoff Size to"
            Select a new size from the dropdown.  (This can be a higher value since you control what you send and can decide to leave it as draft or send immediately after reviewing the email and it's size.)
      Click OK to save settings.   These new size limits will be set on the CruisersEmail server the next time you perform an email send/receive.

Using CruisersEmail and Outlook with TripMode

  3. Launch CruisersEmail and Outlook
