No webmail storage

[Machiavelli1527]

My webmail does not retain inbox emails. I have been told that the problem is 1. defective Outlook (even when all send/receive is done in webmail. 2. MS Security Essentials is inadequate (causing the Verizon default storage to empty!) 3. Malware is causing it (with no malware found by two malware search apps - runs of complete disk.. 

This is combined with every incomng to my default Outlook email address showing up duplicated or triplicated. 

Five techs went through failing gyrations and finally a "network specialist" pronounced "Malware" and that was that.

I have been computer literate since 8" floppies and have never been unable to fix or workaround any problem, but this?

I'm sorry that your having trouble with the webmail. There could be a couple things going on. I have sent you a private message to get additional account information.

Never got your private message. Resend, please.

If webmail is losing emails, odds are there's a client somewhere pulling email from the server. This could be on a pc, phone, or other device. Even if you have no idea where the offending client is, you should be able to resolve it by simply changing your webmail password to something different. This will stop the client from authenticating, and it won't be able to remove your mail anymore.
