COM Object gets Message stating it cannot access the server.

Question

I support an Application that would call Outlook to send an e-mail, it uses a COM object to do so, I have a client that has Exchange 2013 and Outlook 2010, trying to send an SMS to a Cell phone, in the form of [PHONE_NUMBER]@vtext.com (Verizon SMS), gets
a message stating that the server cannot be reached (Retry/Work Offline / Cancel), If I select Retry, nothing happens, if I select Work Offline, it will take it to OUTBOX but will not send it, unless outlook is closed and then re-opened. However, if I add
a CC email address, the CC'd email will be sent right away once the message is put on the outbox, but the original phone_number email will stay in the outbox.
Haven't seen that specific behavior before.
Any light would be greatly appreciated.

Answer 1

Sending an Email/SMS is a small feature that was added to the application to make it easier for our clients to communicate the Service Calls to the technicians, send Reports, and/or send Invoices/Quotes to their clients.
That being said, the Application was working fine with Previous Outlook Versions up to 2010 (though not quite sure what changes were done by the Patches, it has stopped on some of the 2010 versions (specially on 64-bit environment) Our developers purposely
selected to call the COM object for the user/client to have full control of the communication (client still needs to click the "ALLOW" Button to allow the email to be sent.
Application is not a plug-in (Add-in) to Outlook, but rather a Full "Service Company Suite" with Email capabilities. It was not Written in .NET or VS so using .NET Objects at the moment is not a choice, unless the developers create some soft of connector
plugin to talk to Outlook.
The Link provided really has nothing to do with the issue (the SMS is really sent as a regular Email)
