We have a SM4.3 system that we have been using forever as just a List Server for the business. Yes, I know it is old, but it works well and if it isn't broken, we don't fix it. :)

I noticed 2 days ago that the daily email did not show up. This happens sometimes for various reasons, so I never thought much of it, but nothing showed up again today.

 

I logged in as my user first and all mailboxes etc seemed fine. I then logged in as Administrator and all the aspects of the server seemed to be functional. The spool count showed it had email in it, so I decided to check it out. After a few seconds it threw an error message as follows :

 

/SystemAdmin/frmSpool.aspx

It won't let me into the spool. I don't think anything is being delivered, but hard to tell. I sent a test email to it, and I never received a failure, but I never received the email either.

I have been looking through the Spool / SubSpool directories in Windows and I can see emails in all of them except SubSpool #3 and #4. These folders also do not seem to have the normal "Failed" sub folders.

 

Could this be a matter of the Windows file structure being corrupted where the spool resides? or something else?

Any help and insight would be beneficial.

Thanks.
