How to tell if you're using Outlook COM or App for Outlook?

(0) ShareShare

Posted on by 323

Hey all, I just started a new job administrating Dynamics again for the first time in a couple years (I'm new to UI) . My first big task is to make sure we are ready for the Outlook COM deprecation, and moved to the App. I've been nosing around the settings and it looks to me like we are on the App correctly, and not relying on the COM add-in, but I want to make sure before I report back.

Can you tell me if there is a way to double check nobody is using the COM addin?

    Hi Toni,

    1. Here is an article which talked about comparison between App and Outlook COM, you could take it as reference:

    https://www.alithya.com/en/insights/blog-posts/microsoft-dynamics-365-outlook-client-vs-dynamics-365-app-for-outlook

    2. Comparison between two products has been also mentioned in this official documentation:

    https://aka.ms/OutlookCOMPlaybook

    From 1 & 2, the most obvious difference for us would be that Outlook COM is built on legacy web client, its icons and UI are not as modern as UCI.

    3. In my opinion, due to they are built with different technology, so web pages for them shall be different.

    To confirm this, I ran a custom javascript on Email entity > Email form, it will get URL of current page and populate it to description(email content) field.

    function getClient() {
        debugger;
        Xrm.Page.getAttribute("description").setValue("Your client is: "   parent.location.href);
    }

    If I create an email from Dynamics directly, it will display as:

    orgURL/main.aspx?appid=xxxx&pagetype=entityrecord&etn=email

    If I create an email from App, it will display as:

    orgURL/uclient/main.htm?appid=xxxx&clienthost=3&liveid=1&org=crmxxxx&pagetype=entityrecord&etn=email

    pastedimage1586226851379v2.png

    there are some parameters in URL which tell us web page will be different for different mode.

    I haven't Outlook COM client for test, but it shall also has its own parameters because it is based on legacy web client.

    Regards,

    Clofly
