Overview

The purpose of this article is to provide information to resolve when a customer is using Office 365 in hybrid mode and when sending faxes from Outlook, they do not arrive at the FaxMaker server.

Solution

To be certain mail is not arriving at the Faxmaker server, please do the following:

1. From the services.msc, stop the FaxMaker Message Transfer Agent service.
   
   
2. Navigate to the C:\Program Files (x86)\GFI\FaxMaker\sinkdrop folder
   
   
3. Send an email that should go to the FaxMaker server and confirm if the .eml file arrives in the sinkdrop folder.  
   
   
4. Usually, with these symptoms, the email sent does not arrive in the sink drop folder.  If this is the case, proceed with the steps below and restart the Message Transfer Agent that was stopped in step 2.  

If the email does arrive, restart the Message Transfer Agent that was stopped in step 2 and ensure the file disappears and Log into the Web Interface and use the FaxMaker Monitor to verify the fax is sent.  

When dealing with Office 365 in hybrid mode and communication with FaxMaker, there are a few steps to take to ensure this is set up correctly and these are listed below.  

1. Create a send connector for mail flow to FaxMaker and point that mail flow to the on-premise Exchange server.  
2. Using the FaxMaker Mail Server Settings article, verify the Exchange connectors are in place and the IIS SMTP settings for the SMTP server on the FaxMaker server are set correctly as well.  

Confirmation

After creating the send connector in Office 365 to route mail intended for FaxMaker to the on-premise Exchange and ensuring Exchange connectors are set up to send mail to the FaxMaker server, faxes sent from  Outlook will function properly.
