Hi there,
I can see why this situation is concerning. It looks like your account may have been accessed by someone else, which can prevent you from sending or receiving emails even after changing your password.
The first thing I’d recommend is double-checking that your password change took effect and that you can log in from a trusted device.
Next, make sure your recovery email and phone number are up to date, and enable two-factor authentication if it’s available to add extra security.
It’s also a good idea to scan your devices for malware just in case any keyloggers or malicious software are present.
Could you tell me if you’ve been able to log in successfully since changing your password, and whether you’ve noticed any unusual activity in your sent folder or other linked accounts?
This will help me guide you through the next steps to fully secure your account.
Regards, Aron
