Hello,

I would like to disable Sent Items on my mailbox by Powershell.
I know That I can disable it on Outlook desktop, but that account just works on outlook web.

I've read some foruns where I could turn this attribute to $False, but it just works in SharedMail Boxes

Set-Mailbox EMAIL -MessageCopyForSMTPClientSubmissionEnabled $False

Anyone knows with attribute I could disable to a "regular" mailbox?

Thank you so much

    Ok so you dont want sent items saved. There isnt a way to do that using Outlook Web App, just outlook as you have seen.

    The other option is to use an retention policy that removes the sent items and apply to that mailbox:

    Otherwise you will have to remove manually.
