Hi Shark Keeper,
Unfortunately what you're seeing is an interaction between the Insider build and Mac High Sierra. It's a known issue with the latest build of Insider Office, and is actively being worked on by the product team.
It was first reported a week or so ago, and a number of people have reported it. We don't have a fix yet, but the product team has said we should see a fix by the next build.
However, in the mean time a couple of workarounds have been suggested.
- Use time machine to roll Office back to an earlier version.
- Uninstall Insider Office, and reinstall the production version from the Office 365 site.
I haven't specifically heard how these work out. There is also an issue with Search and replace in Word with High Sierra, so I'd suggest uninstalling and reinstalling the production version of Office rather than individual apps.
Sorry about this issue, as you mentioned wanting to try out an Outlook plug-in, and it affected other apps.
We're monitoring the progress of the product team and will get out news as soon as we have it.
Thanks for your patience.
-Jay
