VSTO Word document in Onedrive for Business not trusted by Microsoft Word

[Shresht-Gatla]

Hi @MikeWilliams-UK,
I am a student, who is working part-time in a private organisation, as an Office developer. I am creating this issue to receive some guidance from you on how you solved the issue regarding the VSTO Word document, which is in Onedrive for business, cannot be accepted/opened in Microsoft Word because it is not in a trusted location.
I made a VSTO word document using Visual Studio and also published it, but the problem is I could not open the VSTO template on files that are in Onedrive for business. I was searching for some solutions, I found that even you were in a situation similar to that of mine. I saw your approach on how you got through it in your Wiki https://github.com/MikeWilliams-UK/Word-VSTO-Template/wiki/5.-Documents-saved-to-OneDrive. I tried your steps but still, I could not solve the issue. Is there any way you could guide me in solving it?
Thanks

Did you incorporate a post build event to set the document's customProperties, this is very important.

Thanks for replying @MikeWilliams-UK, No I did not incorporate it. I used the ClickOnce method to deploy the solution. But still, I will try incorporating it and let you know the results. Thanks for your advice.

From my experiments it is critical that the document's customProperties are set to match the deployed location.
I am not sure that this will be possible with ClickOnce as it may ot be easy to predict the deployment path.

My next step is too create a WiX installer project to

• deploy the assemblies --> C:\ProgramFiles\XXX
• set the deployed location in the template to match above
• deploy the template to the user's templates folder
