I have discovered that my Edge GPO settings, two in particular, are breaking our office/outlook add-ins within Microsoft 365 / Office 2021 desktop applications. FindTime is the main add-in we use, but it also affects our PhishNotify add-in, which means I'm sure it effects more.
The two policies in question are as follows (Edge Policy files from 95) :
Browser sign-in settings: Enabled - Force users to sign-in to use the browser
Control where developer tools can be used: Enable - Don't allow using the developer tools
While I understand that my problem is in Office, Outlook specifically, these are Edge policies causing the issues.
With these enabled the following happens:
Browser sign-in gives the error: Add-in Error This add-in could not be started. Close this dialog to ignore the problem or click "Restart" to try again.
If I change the browser sign-in policy I get a white screen where the addon UI would be.
The edge policies seem to apply to Office version Monthly Enterprise Channel 2108.

@KrisNelson Hi! Just to confirm, you mentioned Office 2021 desktop applications but is it Outlook on the web where you are reproducing these issues?
Have you tried reaching out to Support (https://microsoftedgesupport.microsoft.com/hc/en-us)? They would be able to work with you directly to investigate and understand your specific set up and scenarios.

A fun update to this. A few days after I posted this issue a Windows Store update was released that fixed the issue.
Not sure how these all tied together to cause the issue other then they are all Microsoft products, but a fix is a fix and that's what I was looking for.
