Sending, receiving, and organizing email in Outlook.com
Hi Sharon Neal
Please note that our forum is a public platform, and we will modify your question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.
I’m sorry to hear that all your Inbox messages, including important pinned emails, have suddenly disappeared.
Since the same issue appears in both the Outlook app and Outlook on the web, please use a computer to open Outlook on the web, then go to Deleted Items and select Recover items deleted from this folder at the top of the message list. If the missing emails appear, select them and choose Restore.
Please also search for a known email using the sender’s address or subject and set the search scope to All folders. Check the Archive, Junk Email, and Other folders as well, in case the messages were moved unexpectedly.
I hope you’re able to recover the missing messages soon. Please let me know what you find in Recover items deleted from this folder.
