Hello Mail Developers - Just ran into this and I have tried many options and just can't get it to work. I am trying to connect to my Gmail account which I had been doing for years, but yesterday it appeared something went off - and I was not seeing the mailbox or messages. I deleted the account from "Internet Accounts" and recreated it - but Mail does not seem to recognize it. See screenshot - Says "Enabled" but the left pane says "Inactive". Now it is doing that for all my 4 accounts in Gmail that I have. Attaching the following images: Internet Accounts - showing one of the accounts which shows the problem Mail/Settings/Accounts Tab - Showing the Enabled but Inactive issue What I have tried so far: Removing all accounts and recreating them Clearing up the following and trying to start all over again ~/Library/Mail folder ~/Library/Preferences/com.apple.mail* Removing keychain entries under Login/Passwords Running Sequoia 15.7.8 (24G814), M1 MBAir, 16GB Latest Update (Tue, Jul 14): Applied the update from this morning 15.7.8 (24G817) and the issue still persists. I am being forced to use an alternate mail client as a result of this major error. Totally at my wit's end on this, so any pointers are really appreciated. Thanks in advance
