Outlook.com'da e-posta gönderme, alma ve düzenleme

Hi Filise,
Thank you for providing the additional information.
I understand why this situation is confusing. Based on what you described, the email address appears to be recognized in one Microsoft account-related process, while the standard sign-in page reports that no account exists.
Unfortunately, as members of the Microsoft Community, we do not have access to Microsoft's internal account systems and cannot verify the status of a Microsoft account, investigate sign-in records, review recovery attempts, or determine why different Microsoft services may be providing different results.
Since you are also not receiving recovery or verification messages at the recovery email address, this issue would require account-level investigation, which is beyond the scope of the community.
If you have not already done so, I recommend contacting Microsoft Support directly and providing the additional details you shared here. These details may help the support team better understand the situation and determine what options are available.
I understand how important access to your mailbox and historical emails is, and I am sorry that the community cannot perform the account-level checks needed in this case. I hope Microsoft Support will be able to provide further clarification regarding the status of the account and any available recovery options.
