Using older versions of Outlook for Mac for personal email and calendar
I’m sorry to hear that the emails in all your personal folders have disappeared, especially since some of them are important.
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.
Since the folders are empty not only in Mail on all your devices but also when accessing Outlook.com directly, this does not appear to be an issue with your Mac, iPad, iPhone, or Legacy Outlook for Mac. The messages may no longer be available in the server mailbox.
As you have already checked the recovery options, rules, searches, and recent account activity, the next step is to contact Outlook Support and request a mailbox-level investigation:
- Open Contact Us - Microsoft Support.
- Select Show expanded list of products.
- Select Outlook > Get Home support.
- Enter Outlook live chat, then select Get Help > Contact Support.
- Sign in with the affected account. If you cannot, use another Microsoft account to access the available support options.
- In the Support Assistant, enter Talk to a live chat agent, then select Contact Support.
- Under Products and services, select Other products > Outlook, then choose Chat with a support agent in your web browser.
When contacting support, provide the approximate date the emails disappeared and examples of missing senders, subjects, and dates.
Important: Chat support is available only during certain working hours, generally Monday to Friday from 9:00 AM to 6:00 PM, and Saturday and Sunday from 10:00 AM to 6:00 PM. If the chat option is unavailable, try again during those hours or request a callback by providing your phone number.
