Sending, receiving, and organizing email in Outlook.com
I’m sorry you’ve been dealing with this for so long, especially when the missing messages affect your bookstore and important events.
Changing browsers may help you access Outlook.com, but it will not necessarily resolve the underlying mail-delivery problem. Please first sign in to Outlook.com using a private or incognito window in an updated browser such as Edge or Chrome. If Outlook.com does not load, temporarily disable any ad-blocking or pop-up-blocking extensions and try again.
Once signed in, please check:
- Junk Email, Other, Deleted Items, and Outbox
- Settings > Mail > Rules and Forwarding
- Settings > Mail > Junk email for blocked senders
- Settings > Storage to confirm the mailbox is not full
Please also send a plain test email without an attachment from a different email account, rather than only sending from the affected address to itself. If messages are missing in Outlook.com as well as the desktop application, repairing Outlook or changing browsers is unlikely to resolve the delivery problem.
Please feel free to let me know if you have any further updates, thanks.
