I am trying to respond to an email for a company, I have already sent the 1 reply 5 days ago.

I received a message from Outlook.com Team ******@outlook.com saying:

The daily message limit helps us free the world from spammers--we're sorry that it's getting in your way. Thanks, The Outlook.com Team .

Does this suggest that someone else is sending messages from my account? How do I find out? I cannot find any information on helping me to sort this out. It's increadbly frustrating.

    Hi,

    Noted. More investigation needs to be done.

    Are you sending to an Outlook group or a contact?

    How old is your account?

    Try switching the Email to Plain Text instead of HTML as a troubleshooting step.

    The setting is below:

    1. Open The Gear icon > Settings.
    2. Go to Mail > Compose and Reply.
    3. Change the message format to Plain text.

    Have you followed all my quoted points, including using the authenticator app and turning on 2FA?

    Remove the signature on the email as well and see if it helps too.

    Hi,

    As the message suggests, they are saying that the email limit is way past the daily limit.

    May I know, on average, how many emails you send per day?

    Sending limits in Outlook.com

    As well as taking a Microsoft 365 subscription, try these tips:

    • Make sure that all your information (like phone number and alternate email address) is updated on your account.
    • Make sure that you have updated your account's profile information (like Profile Name, Photo, Date of Birth, Gender, etc).
    • Make sure the password which you have created is a combination of upper case/lower case letters, numbers and special characters.
    • Make sure that the people you send emails to are added to your Contacts on Outlook.com.
    • Communicate frequently with your Contacts.
    • Use the Microsoft Authenticator app. The Microsoft Authenticator lets you quickly and securely verify your identity online, for all of your accounts.

    I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!
