How do you integrate Exchange with TRIRIGA using IBM Domino?


I’m trying to do a reservation integration between Exchange (Outlook 365) and TRIRIGA. But since TRIRIGA is on-premise, it has several firewall restrictions in order to reach Exchange. As a solution, we are using IBM Domino to relay the SMTP messages from Exchange to TRIRIGA. The flow would be:

  • User books a room on Exchange using the web client.
    • The Send connector sends the email to Domino by using the forwarding contact for the room.
  • Domino receives the email and forwards it to the TRIRIGA server.
    • It should relay the message without modifying it in any way.
  • TRIRIGA receives and processes the SMTP message.
    • What we expected: The reservation should’ve been created.
    • What we see: TRIRIGA can’t find the room. It seems that the SMTP message is missing the “spec_id” of the room.

Has anyone implemented a similar solution? From Exchange to Domino to TRIRIGA? If yes, how did you configure the environments? Where should the “spec_id” be in the SMTP message that is sent to TRIRIGA?

Are file attachments in Outlook also attached in SMTP messages?


In the context of TRIRIGA Reservation Management (Reserve), if a user attaches a file in a meeting invitation (in Outlook) while booking a room, is that file going to be attached in the SMTP message that is sent to TRIRIGA? Has anyone tested this or have the ability to test this?

The concern is around confidentiality. If someone attaches a company confidential document and the message is sent over SMTP (non-secure) to IBM Cloud (TRIRIGA SaaS) with the attachment, the document was now exposed to the public internet.

In your scenario, the Send connector configured in Exchange is responsible for sending the message to TRIRIGA. I believe that, by default, the Send connector will also send attachments. There may be some configuration on the Exchange side that prevents or limits a particular Send connector from forwarding attachments.

IV95388: TRIRIGA Reserve Outlook add-in fails when using only TLS 1.2


Due to security regulations, certain customers must disable TLS protocols 1.0 and 1.1. However, when they do this and use only TLS 1.2, they lose connectivity from the TRIRIGA Reserve Outlook add-in.

The problem was that the add-in was compiled with .NET 4.0 which doesn’t support TLS 1.2. The fix is to explicitly force support for the TLS 1.2 protocol. Moving forward, the IBM TRIRIGA Workplace Reservation Manager add-in is now able to communicate with the TRIRIGA server over the TLS 1.2 protocol.

Why does Outlook add-in connect to server when opening meeting?


When opening any meeting in the Microsoft Outlook calendar, the TRIRIGA Reserve Outlook add-in will connect to the TRIRIGA server and send a small package.

This happens regardless of whether the meeting was created with the TRIRIGA add-in or not. When opening an appointment (which has no participants, in contrast to a meeting), there is no connection to the TRIRIGA server. It can be reproduced by opening Fiddler, opening Outlook, and then opening any item in the calendar that has participants (i.e. a meeting).

The consequence of this is that a session is opened for the user on the TRIRIGA server, taking up capacity on the server, thereby reducing the number of real users that the system can support. Has anyone else noticed this behavior? Can it be changed through configuration?

IV90194: Outlook add-in install fails on Program Files folder


If you attempt to install the Reserve Outlook add-in into a folder within C:\Program Files\… the information provided on the command line such as URL is NOT copied into the user’s outlook.properties file. However, if you select any other folder in the computer as an install location, then the details are updated into the outlook.properties file.

The problem with using any other location is that those locations are not trusted by Windows. As such, the application when invoked forces a popup which, due to the expired application signing certificate, is not pretty. This is quite scary and is likely to result in many of the users declining the installation.

Because the files are sent to the users’ computers silently, they will not be aware that the add-in has been deployed into their machine. Any popup around email is worrying, so it is easy to see people taking the Don’t Install option.

Why don’t buttons display in the TRIRIGA Reserve Outlook add-in?


The Outlook Reserve add-in is not functioning properly. What I see inside the app is that the top of the form inside the add-in appears momentarily, with the “Book Selected Room” button nearly off the page, such that you can only see the left edge. Then that whole bar goes away, including the button. The “Book Selected Room” button at the bottom and most other controls never come into focus. So no reservations can be made.

It is necessary to ensure that the correct registry entry exists, and that Internet Explorer (IE) Compatibility View mode is not set. The registry location is different depending on whether you are running the 32-bit or 64-bit version of Microsoft Outlook:

  • With 32-bit Outlook, this is the registry key that will matter: HKLM/Software/Wow6432Node/Microsoft/Internet Explorer/Main/FeatureControl/FEATURE_BROWSER_EMULATION
  • With 64-bit Outlook, this is the registry key that will matter: HKLM/Software/Microsoft/Internet Explorer/Main/FeatureControl/FEATURE_BROWSER_EMULATION
