got a new MacBook Pro running Monterey. 12.6.8 -set up Mail for my usual email servers. The read messages are not visible past 30 days or so. In other words, I can't see messages from mid-July now, even though I haven't deleted them

Double check mail settings for mail day to sync - change it to your desire.

I have four email accounts in Mac Mail. Until recently, all accounts showed all emails that were not trashed going back many years. Now, all of a sudden, one of the Mac mail accounts only shows past email from the last 10 days. When I open Time Machine and select a date from several months ago, it also shows only 10-20 emails as of the prior date, but nothing earlier in time.

Help, please.

I have the same issue, with one inbox only showing emails for the past 10 days. When I use Time Machine to look back several months, the inbox has only 10-20 emails as of the selected date. There should be thousands of old emails still in the inbox. Our other 4 Mac Mail accounts still have inboxes with thousands of past emails.
