Using older versions of Outlook for Mac for personal email and calendar
I’m sorry you are experiencing this, especially after your account was compromised.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.
To identify whether the issue is caused by Legacy Outlook for Mac or the mailbox itself, please completely quit Outlook for Mac. Then, sign in to your account through Outlook.com in a browser and send yourself a test email.
- If the test email remains in the Inbox, the issue is likely related to the Outlook for Mac profile or a local setting.
- If the email still moves to Deleted Items while Outlook for Mac is closed, the issue is occurring at the mailbox level.
Since the account was hacked, please also review the account’s security information and remove any unknown devices, aliases, sign-in methods, or app passwords. Changing the password may not automatically disconnect every session created before the password change.
If the issue also occurs on Outlook.com and no suspicious settings are visible, please contact Outlook.com Support through Help > Help in Outlook.com so the mailbox can be reviewed.
