Hi @Robin Zacharias , I’m glad to hear that your issue has been resolved! It seems like the problem was likely due to the synchronization settings between Outlook and Gmail. When you renamed the “YYarchive” folder to “ZZarchive” in Outlook, Gmail might not have immediately updated this change, hence the “YYarchive” label was removed and “ZZarchive” was not added. As for the email deletion issue you mentioned, this could be because both Outlook and Gmail use the IMAP protocol, which allows for synchronization of emails across multiple devices. So, when you delete an email from the “Inbox”, it also gets deleted from “YYarchive” because these two folders are essentially different “views” of the same email. If you are still experiencing duplicate emails in your inbox, you can try unsubscribing from the “All Mail” folder in Outlook. To do this, right-click on the folder and choose “IMAP folders,” then select “Unsubscribe All mail”.
Also check Gmail's settings: Log in to Gmail web, go to Settings -> Labels -> and set the labels you don't want to sync with Outlook to not show up in IMAP access.
