Sending, receiving, and organizing email in Outlook.com
Hi @Lee
The cause of this problem may not actually be related to email sending limits being exceeded. You may also encounter similar warnings because Microsoft considers the account to be suspicious due to incomplete security steps.
There are a few troubleshooting steps I can recommend to you.
- Go to this link and check out "How can I increase sending limits?". https://support.microsoft.com/en-us/outlook/sending-limits-in-outlook-com
- Your account may have been newly created or marked as spam account. Accounts verified with a phone number are generally considered more secure. If your account is new, please complete your security steps. Adding MFA and recovery email addresses may help.
- Your account may have been stolen; check the Sent Items, Deleted Items, and Junk folders.
- If the VPN is on, signals coming from different IPs and regions at very short intervals may have caused some restrictions on your account. If your VPN is on, turn it off and try again later.
If these steps are not help to you, feel free to contact to me again.
Best.
