Outlook Email Errors

Marlin GTX email errors when using Microsoft O365 can often be solved by setting up two-factor authentication (2FA) & creating an App Password in the email account, and then entering the app password into your Megalink Configuration settings.

By default, Microsoft is now requiring all users to set up two-factor authentication on all emails used with the Microsoft 365 program suite which can prevent Megalink emails sent from within GTX from being delivered, if it is not set up correctly.

If you are getting the above email error, this can most likely be solved by setting up the 2FA authentication and then entering the app password in your Megalink control panel.

Setting Up Microsoft Two-Factor Authentication (2FA)

If you have not already enabled two-factor authentication (2FA) for your Microsoft Account, you should be prompted to Keep your account secure each time you log in.

To use two-factor authentication, you will need to download the Microsoft Authenticator app onto your phone, or other device, if you do not already have it installed.

Once the app is installed, click on the Next button at the bottom-right of the pop-up, until you see a QR code, which can be scanned using your Authenticator App.

In the Authenticator App

Once the Authenticator app is installed, open it on your phone (or other device).

If you get a notification asking to allow the Authenticator to take pictures and record video, select on While using the app.

Tap the + button in the top right corner of the app screen (bottom-right if using Google Authenticator).

When prompted, select Work or school account.

Then select Scan a QR Code.

Use your phone/device camera to scan the QR code in the Outlook pop-up window, which will bring up a six-digit code.

Return to the Outlook pop-up window, click on Next and enter the code in the following window.

Now, when logging into Outlook, you will be prompted to authenticate the log in using the Authenticator app.

To resolve the email errors though, you will still need to set up an Outlook App Password and enter it in GTX's Megalink Control Panel settings.

Setting Up An Outlook App Password

Once you have set up two-factor authentication, log into Outlook.

In the top right corner, click on the circle with the user's initials in it.

Then click on the blue View Account link that appears in the pop-up menu below.

The user profile screen will open.

At the top-left, under Security Info, click on the blue Update info link.

On the following screen, click on + Add Sign-In Method.

In the Add a Method window that pops up, select App Password from the drop-down menu.

In the following window, enter an appropriate name for the password (eg. "GTX" or "Megalink") and click Next.

You will then be presented with the App Password which then needs to be copied (by clicking on the button next to it) and pasted into GTX's Megalink Control Panel settings.

You will then be presented with the App Password which can be copied by clicking on the button next to it.

The Outlook app password now needs to be entered into GTX's Megalink Control Panel settings.

Entering the App Password in GTX

Once you have set up two-factor authentication in Outlook, you need to copy the resulting App Password into GTX's Megalink Control Panel settings.

Stopping Megalink

Before editing the Megalink Control Panel settings, you need to manually stop the Megalink service.

This can be done by opening the Services application from the Windows Start menu.

In the Services application, select the Megalink service and click on the Stop the service option that appears in the right tab.

It is now safe to make adjustments to the Megalink Control Panel Settings in GTX.

Entering the App Password in GTX

Once the Megalink service has been stopped, open GTX and click on the Megalink tab at the bottom-right of the application window to open the Megalink Control Panel.

From the Megalink Control Panel menu bar, select File > Configure.

The Megalink Configuration pop-up window will open.

Paste the Outlook app password into the Outgoing Server Password field.

Click on the Save button at the bottom-right and then exit out of the Megalink Control Panel window.

It is now safe to restart the Megalink service.

Restarting Megalink

Once the app password has been entered and saved in GTX's Megalink Control Panel, return to the Services app and click on the Restart the Service option below the one you used to stop Megalink originally.

After doing this, you should not experience any more email errors.

If the errors continue, please log a ticket with the Megabus Support Team.
