The case of the disappearing emails

This post brought to you by Peter Perry.  We're going to call this the case of the disappearing emails.

The symptoms:  Emails continuously disappearing and reappearing mostly right before your eyes.

The participants:  A SBS 2011 server.  Symantec SEP SBE 12.1 client installed.

The issue:  Symantec SEP SBE 12.1 is not adding the exclusions for Exchange IS for SBS 2011.  It does for SBS 2008, it does not for SBS 2011.

The solution:  Manually enter them until the Symantec team resolves the issue.

http://social.technet.microsoft.com/wiki/contents/articles/953.aspx  The list of exclusions you need to do for antivirus is long. On a personal note, I don't think antivirus is a knee jerk "you must have on the server" these days.  You need to look at how the server is used, if they have a mail hygiene engine in front, if they use web filtering software.  You have to look at the risk of antivirus (yes, the risk of antivirus) and balance it with the need for it.

Hello, Susan,

was the store moved to another partition in sbs?

Normally all exclusions for DCs and exchange (incl. 2010) where set automatically by SEP EE 12.1 and SEP SBE 12.1, but the products expect these files and folders at their default location.

Symantec recommends to set exclusions manually for non-default paths and they recommend to verify the client´s exclusion list, as described in www.symantec.com/.../TECH105814

Regards,

Rolf

I have exactly the same problem but I can say that it only happens if the email has been opened. If something is just previewing in the reading pane, it doesn't happen.

If I open the email or a reply window, as soon as that window is closed the email in question and all emails related to the conversation disappear. If I had to guess I'd say this happens about once a month on average.

I do not use Symantec but rather ESET NOD32. My environment is SBS 2008, Win 7 64 bit with Office 2010.

Check your outlook rules. It sounds like it's being sorted by a rule.
