Get Form Region fields from Outlook item?

Does anyone have any suggestions for how to get the custom Form Region fields from an Outlook item?


For those wondering, form regions are "custom pieces of user interface that can be used to customize a standard form."


We have a custom Outlook Add-In that creates Outlook items that contain user input in a form region.  When that item is updated, I want my flow to be able to read those fields.


Alternatively, are there are other ways to store custom fields in an Outlook item that Flow can access?

Hi @grahampasmurf,


Could you please share more details about the custom Form Region fields from an Outlook item that you mentioned?

I haven't ever created such a field currently so I couldn't help provide the solution.


Please share more details so we would try to provide a proper workaround for you.


Best regards,


Sure, let me elaborate.  This is an example screenshot of an Outlook item (appointment) that includes this custom form region at the bottom, below the body).




We create this as an Outlook Add-In using VSTO tools and C# code.  In the code that retrieves previously saved custom fields, it refers to these as "Extended Fields" using this syntax,

ExchangeWebServices.PathToExtendedFieldType extVisitorCompany = new ExchangeWebServices.PathToExtendedFieldType();


Is there a way for Microsoft Flow to connect to Exchange to retrieve these Extended Fields?
