Hello! My name is*****
Please tell me if you are using an e-mail program such as Outlook to send and receive e-mails, or you do it via web browser (web mail).
Thanks for the information!
I suggest starting Outlook in Safe Mode to see if it will allow you to both send and receive e-mails.
To do that, exit Outlook and then press and hold the Ctrl key while double-clicking the Outlook 2010 icon. You should see a dialog asking you if you want to start Outlook in safe mode so click Yes.Leave Outlook in Safe Mode for a while and let me know if you could send and receive e-mails as before.
