SBS 2003, Fax Service and Office 365: How to make it work
Posted on 2012-09-08
Customer with SBS 2003 migrating Exchange to Office 365. There are multiple apps in the network that sends e-mails and all of them have been tested to relay correctly by using the given Office 365 server on port 587 using TLS.
But it seems that even though the same settings used by the other apps are in the Fax - Properties - Receipts tab, the communication can't be made and I suspect that whatever the Fax service is using to SMTP out it is not really using TLS as there is no place in the properties to specifically say so or it just do not work with other ports than 25, as we tried using other relays on port 2525 and it also failed.
I can telnet the server at outlok.com on port 587 from the SBS box with no issues, so it is not traffic/firewall related.
The error when the incoming fax is tried to be routed to e-mail:
Log Name: Application
Source: Microsoft Fax
Date: 9/8/2012 11:44:54 AM
Event ID: 32083
Task Category: Inbound
Unable to route fax C:\ProgramData\Microsoft\Windows NT\MSFax\Queue\1CD8DD8C65A47.tif to the requested e-mail address.
The following error occurred: 0x8004020E
This error code indicates the cause of the error.
Check the SMTP server configuration, and correct any anomalies.
So, the question is: Can the Fax Service be configured some how to use TLS and to send to other ports than 25?
