Outlook Proplus- Mail stuck in Draft

[BINODMAHARJAN2022]

One of my client laptop, Outlook version 1902, proplus installed. She has issue with draft mail. Whenever she send mail either new thread or reply that mail will be send and one copy will be drafted.

1. I have uninstalled office app and also recreated profile too.
2. There is no such setting configure to copy in draft, it's in default setting.

Is that a bug or issue with version or else?

@BINODMAHARJAN2022 Is this an IMAP account?  That is not uncommon with imap. You can try raising the autosave time in File > Options so fewer drafts are saved.

Hi @Diane Poremsky 

This is Exchange Type mail, i have updated office package version to latest till same. I even don't know why that specific user have such issue.
