I have noticed duplicate emails is still a problem with eM Client using Gmail. I have disabled all “special” Gmail labels to show in IMAP folders, except “All Mail”. However, flagged emails are still duplicated.
If I also disable “All Mail” to show in IMAP folders, how does the eM Client Archive button work? Will it still move emails to the All Mail Gmail folder? Or, will it become disabled? Will eM Client error and catch fire?
I’ve found there is just no way to stop flagged emails to be duplicated in eM Client, unless all Gmail labels are disabled from IMAP except Inbox, Sent, Trash, Drafts and Spam.
