Full cleanup of ALL accounts is not a solution(and re-add even helps not). I also noticed that some IMAP settings — like the root folder path (e.g. "INBOX") — are not available in the new Outlook, which makes troubleshooting more difficult. In the classic Outlook, I would normally check or adjust these. All default folder will show up as top-level ones and mail will start populating to the Inbox folder. For faster and more reliable delivery, add to your trusted senders list in your email software. Simply enter your email address OR username in order to reset your password.

Maybe some encoding behavior or just a different linefeed or something that has changed over the Fix Outlook and Office365 Sync Issues years... I’ve never heard of setting a path before for email, so apologies if this is a simple solution to those who come across this in the future. If you can, turn off IMAP, require 2FA, and use the native outlook client. Having the same issue with some of our accounts on IMAP as well.

My accounts in Mail app stopped to sync post update

See the attached picture for the Properties window for a user-created folder. When you right-click one of the folders that doesn't show new mail unless you select it, Properties, is the box 'When getting new messages... It's usually not checked by default for IMAP to minimize network traffic. Subscribing to a folder makes it appear in the Folder Pane, but one might not always want a folder to be synced automatically if it is mainly an archive folder or one that seldom receives new mail. This limits the amount of network traffic and improves performance for syncing important folders.

If the proxy directs requests to a newer IMAP server implementation (f.i Cyrus imapd 3.6.1), the iOS 18 Mail app works as expected, even the requests are handled by the same IMAP server proxy. Suspect some Apple Dev's have been lazy with some code in IOS18's mail.app and its causing the issue. Decided to just try completely removing my Gmail account, the one that wasn’t syncing with the Mail App after the iOS 18 update. I know this is not very helpful, but we ran into exactly the same issues as you with one of our clients using Outlook 2010/Win7 and Godaddy’s IMAP mail and never truly figured it out.
