Hi Paul,
Thanks for your response.
I did see that note in the Tips & Tricks topic, but I'm not sure how it applies here. The Microsoft support page it links to seems identical to
the page I used, except that "originaldougal.com" seems to be geared towards more recent versions of Office.
And the issue I'm running into isn't that my "data source fields are converted to plain text," but that the underlying link is being changed from my desired URL (e.g., "www.bing.com") to a different, broken URL (e.g., "https://my.sharepoint.com/personal/Documents/www.bing.com"). I can't seem to find any guidance on this elsewhere.
I fully acknowledge that I may be missing something obvious that you're trying to point out - so just let me know if that's the case! Thanks for sharing your thoughts.
Cheers,
Benjamin
