Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. Since you are using a Microsoft Exchange email account, all your emails are intact in the server and only your MS Outlook is having issues. In particular, this is an issue with your email profile.

If the problem continues, please let me know, I will be here to assist you further. Also, if you want, I can remotely access your computer so that I can directly fix the problem while you watch.
Please let me know so that I can help you further.
