Cause

The BIN folder content
<drive>:\OfficeMail\Websites\PIOfficeMailUser\PIOfficeMailUser\bin
and several DLL libraries are different from the ones we use in Officemail 3.9.0.1.

 

Resolution

UPDATED: April 13, 2017
The BIN folder content and several DLL libraries are different from the ones we use in Officemail 3.9.0.1.
The customer received ZIP file with DLLs that the log file is asking for and has been asked  to backup the BIN folder first at:
 <drive>:\OfficeMail\Websites\PIOfficeMailUser\PIOfficeMailUser\BIN
and replace the DLLs that were sent. It may be needed to restart User Website from IIS Manager to apply it.
