Utilização do Outlook para iOS em ambientes empresariais para e-mail e agendamento
Dear Samanta V. Mello
Thank you for using Microsoft products and posting them to the community.
Depending on the description, the email will be sent to an Outlook mailbox that you don't know.
We need to make sure that your inbox settings haven't been changed or something else is going on.
You can access your inbox on the web outlook.live.com, click Settings (gear icon) in the upper right corner, click Mail - Forwarding to see if there are any abnormal redirects, if there are any, delete them and then Mail - Rules to see if there are any abnormal rules, if there are any, you have to delete those as well.
First, you can check if this setting is normal.
If the settings are normal.
It could be the fact that your mailbox was connected to the third-party platform by hackers, configured with the POP or IMAP protocol, and then the third-party platform was configured with redirection and you did not change your account password, causing that mailbox to connect to the third-party platform. You described that you no longer receive emails messages.lifepointspanel.com, I don't know if the hacker enabled "delete copy" when he set up forwarding, which caused the server to delete the emails during the synchronization process with the server.
You can try the following method:
You can log in account.micosoft.com your account on Microsoft's official website, click Security - View Credentials, and check for abnormal credentials, especially for successful login. You can change your account password to protect your account's security.
Then, under Security - Manage login methods under "Sign out everywhere", you will see Sign out of all trusted devices, browsers, and apps, this will take effect after 24 hours. This interrupts the situation I described above.
You can also click on the link below after logging in with your account. You can view all the platform permissions, and if there is a message for a third-party platform, it means that you will continue to receive messages from the third-party platform through your inbox's email manager. You can click Edit to remove the permission.
