When I open the Mail Activity Viewer I notice that Apple Mail is forever stuck "Indexing…". It never moves past roughly 5% complete (see the attached screenshot).

Is anyone else experiencing this behavior?
I haven't been able to figure out what is causing it. I have a fast internet connection (fiber), so I know it is not that.
Is there an associated issue with Mail...?
To be honest I never in 20 years looked at that "Activity Viewer" and yours is the first question I remember seeing asking about it.
Same information (seemingly,) that gets reported at the very bottom of the mail column, ex:
You can see Server information, maybe there is a clue if you are reaching maximum capacity of the inbox...or some such(?)
My only suggestion would be to rebuild the Spotlight index( same index Mail uses) and compare your results.
