Sending, receiving, and organizing email in Outlook on the web for business
Dear RebecPFca,
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
If the recipient of your email has already read it before you recalled it, the email will not be deleted from their inbox. However, they will receive a notification that you have requested to recall the message.
This is because email recall is not a guaranteed process. It relies on the recipient's email client supporting message recall and the recipient not having already read the message before the recall is processed.
The fact that you are using a cloud-based Microsoft system and sent the email using your org email to their org email does not affect the outcome of the recall.
If you are concerned that the recipient has still access to the email, you can try contacting them directly and asking them to delete it. You can also try to send them a replacement message with the correct attachment.
Thank you for your precious time. Have a nice day.
Regards,
Microsoft Community
