An early version of a Message Recall Request status report (image credit: Microsoft) Microsoft also promises a new aggregate message recall request report to show how successful a request is and who has managed to read a problematic message (see below figure). The work to build a new recall function is ongoing with no committed dates. Given the number of clients involved (especially Outlook desktop) and the complexity of rolling out new functionality across Office 365, it’s unlikely that we will see the new recall function much before the second quarter of 2020. It's got nothing to do with Outlook but the email server connected to Outlook. If you can hold off making a fool of yourself until then, the new message recall will help.

If your email server supports this, like Microsoft Exchange, yes the message can be recalled from internal users of the same email server, i.e. If the email has been opened by your coworkers, no recall, since it's been read already anyway.
