iMap Mail Clients not syncing all emails with server
Content
I am aware of the difference between Gmail's labels vs. Outlook's folders, but I would expect that Gmail does what is necessary to make the folders appear correct over the IMAP connection to Outlook. For example, if I drag a message from Outlook's All Mail folder to Trash, I see that message disappear from the Inbox folder after a short delay. Hence, the trashing of messages is registering on Gmail. It's just that the contents seem completely disconnected from what I see using webmail.
Why IMAP Folder is Not Properly Syncing?
Meanwhile, the "connecting" or "Checking for mail..." just stays on the bottom status bar of the mail app. I deleted the Apple Mail repair corrupted ost in outlook app from the phone, reinstalled from the App Store. So only wait when some "smarties" from apple IT solve problem in app ... Apple programmers use no CD/CI - simple sometimes update by "sales-manager requests", and without any critical-bug-checks ... Full cleanup of ALL accounts is not a solution(and re-add even helps not).
Chosen Solution
Suspect some Apple Dev's have been lazy with some code fix MFA prompts not working in IOS18's mail.app and its causing the issue. I was a little hesitant but went ahead and let it completely remove all the synced items from the account off of my iPhone. After a minute, it was removed so just went and re-added it and BOOM. Decided to just try completely removing my Gmail account, the one that wasn’t syncing with the Mail App after the iOS 18 update.
IMAP folder sync issue in the new Outlook (moved emails not syncing to webmail)
The responsables of the mail told us to move all the mails from past years to a new account to reduce it's size, but after doing that it doesn't seems to be working. This problem isn't anything new, this happens every year or so, but this time it just isn't getting fixed.

Some reference links I read thru though I don't fully understand all of what is being discussed. I have not tried the add-on yet I am going to experiment.
These are the common reasons why the IMAP folder is not syncing.With the help of this, you can also ensure that the server settings are properly configured or not.I use both webmail and Outlook desktop client to access my Gmail.If the server is down and you are experiencing issues, the problem IMAP folder is not syncing occurs.And because of the size, this is making the mail simply stop working after one day of normal use, forcing the users to end outlook process to make the mail sync again properly...So, properly follow the above steps and backup your data from IMAP folders.So it must be something in IMAP protocol handling on the old server that makes the iOS Mail app go out of sync or crash the syncing mechanism on the iOS device.
My accounts in Mail app stopped to sync post update
Simply making a change in Outlook does not in and of itself mean that anything has changed in Gmail. For example, you can disconnect from the Internet and make changes. Outlook needs to explicitly reach out to Gmail and communicate flush DNS and re-sync Outlook the changes you've made. I would suggest that frequent changes to folder contents on multiple devices will make it go wrong.
