Does macOS Monterey limit the number of messages available in Mail?

I switched to Spark and just keep Mac Mail as a search tool. Spark seems to show all emails beyond the last 10,000 in the inbox, but search facility is far from ideal as it misses about 70% of emails that the Mac Mail finds on keywords searched. Afaik Mac Mail holds emails on your drive where as Spark only accesses your email provider server (mine is Yahoo). So it's much faster, but also suggests Spark is not accessing all of my past emails.

It's annoying. Especially as nobody seems to want to own up to the change. I'm convinced now that it is not a Mac OS issue but an email provider issue that they simply don't want to acknowledge or reveal the details behind.

I was so excited for a solution to this, and immediately went and tried this once I saw it. It breaks my heart to say it didn't work at all for me. Back to 9,999 emails. Anyone else try this and fail? Any other workarounds? It's driving me crazy.

I tried it and am deeply saddened to say it didn't fix the issue for me. Wish I had something else to try, or could at least figure out why that worked for some so I could suggest further steps to Apple/AOL.

I have no idea about that.

Are you also having issues on other devices for same account? My yahoo mail is imap on phone iPad and other macs and it is broken on all. I’m going to try removing from my Monterey ststems

All my mail magically returned today with no action on my part. Really wonder what was going on.

Now I need to figure out if I should just keep my POP3 I set up as it worked when iMAP didn't. I'm glad you got your mail back too. Maybe use POP3 to 'back-up' mail locally.

One other thought, maybe it has to do with iCloud? The issue occurs on ALL my devices, Mac with Monterey, Catalina, and Big Sur. Also iPhone, iPad. All inbox are limited.

awesome! Thanks for the follow-up

I'm using Yahoo.mail via IMAP.

Same with my iPhone.

iCloud shouldn't be affecting my emails at all.

Same here. I think iCloud does some sort of sync with mail accounts.

I'm having the same issue on AOL.
