Phishing
I use Outlook 10 with Microsoft exchange. I have one of my email accounts that looks like it is is being phished with emails from the this address 'Postmaster@msg.strl.va.charter.net' indicating I have emails that are undelieverable because other server is not reachable. I have blocked this sender but it is still coming through. Makes me think the pst file may be corrupted and is the source - not external. Anyone had this problem or do you know how to fix it?

Thanks. We'll let you know when a new response is added.

How are you trying to block these? What are the parameter? I assume you are not blocking all from the domain Charter.net. and not all from Postmaster as these would stop valid emails you would want. Here is a link on how to block emails by IP address

    If you have doubt that, pst file is corrupted, you can try to repair with Scanpst, which is a built-in utility.

    Next you have blocked one, but still mails come from this source. Some information is missing. Is this your office/ for personal use? If this is your office, have you brought this one notice to your system admin person? Is there anti virus installed and up-to-date ? Is your system updated with recent patch/ version?

    These particular kinds of e-mails often have nothing to do with anything on your system. And I really don't know if your settings will 'block' an error message -- I can't recall anyone I know ever trying. It seems plausible that error notices would always be allowed through.

    "Phishing" might be involved, but it's less likely that the attempt is directed at you. More likely, the attempts are aimed at whomever the original addressee is.

    Your e-mail address was likely picked up from someone's address book (or web-site harvesting or...) and used as a fake From: address on spam messages. In general, there's nothing you can do about it other than filter these into a folder by themselves.

    Thanks for response.
    This is my personal account but I have two businesses that are also on exchange. account.  They are not affected at this time. 
    So I am my own IT department.  
    I have up-to-date anti-virus and have run it and several alternatives more than once.  Most recent Norton and malwarebytes.
    The blocking is sending "the emails" to junk mail.
    Don't know if directed at me, I just assumed.
    Will think about web harvesting concept and not being the target.
    Thanks again - just don't want to have this to expand.

    I have seen strange behavior with Outlook before. You might consider re-creating your PST file altogether if scanpst doesn't help. That said, I doubt this issue is related to a corrupted PST file.

    After working with MSFT, i have concluded that it is not a corrupted PST file.  I have also talked to my ISP who had flagged my account due to unusual activity (I was getting several hundred of these emails a day).  So they are looking at this also.  The block I mentioned earlier was diverting the emails to my junk folder, but I wanted to get rid of issue.  Finally i ran Malwarebytes again and did pick up some new issues.  

    Anyway, at this point, the activity has ceased.  Not sure the exact reason because some of efforts overlapped with the result it is hard to attribute to one over the other.

    Run a full system scan for viruses on your system. Next contact your bank to report that you may have been the victim of fraud, if any. If the matter serious, file a complaint with the appropriate anti-fraud bureau. As you mentioned, Norton, you can use Norton Power Eraser tool (free to use) for more secured.
