Configuring preferences and options in Outlook.com
Hello,
Due to a lot of spam abuse, Microsoft has placed certain limits on sending. Have you got a Microsoft 365 subscription? Only basic one is also enough to relax limits.

How can I increase sending limits?
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!
