    Outlook 2016 deletes Sent files


    On 2 machines, In my primary email account, If I click on Sent, I see the sent messages. If I just do nothing, after about 5 seconds the file that has focus will disappear. If I don't go to another folder, the next message will disappear in about 2 seconds, and this continues for as long as I have cared to pay attention. The files do not go into Deleted or Trash or anything saved. They are just lost. This is set up as an imap account, and if I look at my Android phone after one of these events, the files are not in Sent or Trash on the phone although files that I intentionally deleted are shown in Trash.
    I discovered that if I copy a few of the sent files to the desktop that seems to stop the deletions. Also, it appears that it only happens if the focus is set on the top item in the list.
    The same thing happens on my laptop, so it would seem that the machine specs are nor relevant. I don't know how to find the Outlook version number, but automatic updates are on, so I expect both versions are current. The Windows 10 version is 1909 on both machines.
    Any ideas?

    Do you know the settings for sent emails? I don't know what 2016 looks like (I'm on 2010), but if you can find the following options window:

    On 2010 the above settings are at File>Acct info>[pick acct]>change>more settings.

    Deleted Files


    I found the screen you were seeing (under Account Setting | Account Name and Sync Settings) and it looks generally like yours. The problem is still there.

    I tried unchecking the box Purge items when switching folders online, and there is no difference. Sent files are still deleted from the top of the stack.

    Does another window define where sent items will be saved?

    Under Outlook Options | Mail |Save Messages a check box says Save copies of messages in the Sent Items folder, and it is checked. That is where I usually find the sent items, and they still appear here unless I leave hte folder open for more than a few seconds
    There is an additional thing different from before: ESet32 pops a dialog box essentially every time Outlook querrys the server. It complains about 2 files, claims the threats are cleaned, but the files do not show up in Detected items or anywhere else. I don't know that it is related, but the two things appeared at roughly the same time. I deleted and re-installed the apparently offending account with a new .ost file, but it made no difference.

    I would disable Eset32 and see what happens.

    That may have located the problem. With ESet email protection disabled, the offending emails became visible. They were not in my primary account, but it was the primary account that had the disappearing file problem. In any case I deleted them without saving the evidence, unfortunately. after opening and closing Outlook several times and re-searching for the offending files (One of them re-appeared, and I deleted again). Now the sent folder seems well behaved. Further, iMap apparently deleted the files on the laptop, and it too is now well behaved. I will mark this thread solved, and thank you very much for the prod which I did not think to try. I am really sorry I didn't save the file so I could turn it in as a bad actor.
