Third-party virus scanners sometimes detect the ClamAV signatures as viruses and move them into quarantine.


Please define exceptions for the following directories in your third-party virus scanner:


C:\ProgramData\JAM Software\ClamAVInABox\Signatures

C:\Program Files (x86)\Common Files\JAM Software\ClamAVInABox

If the Exchange Server Toolbox does not see any emails, it is usually because the Exchange Agents are having a problem (assuming the service is running normally and there are no errors in the Event Viewer).

The first thing to check is whether the Exchange Server Toolbox agents are installed:

  1. Open the Exchange Management Shell
  2. Enter the command "Get-TransportAgent"
  3. There should be a list on which 2 Exchange Server Toolbox agents appear
  4. If that is not the case the easiest way is to reinstall the program
  5. If reinstalling does not fix this issue you can try to install the agents manually:
    1. Open a command prompt with admin rights
    2. Run "C:\Program Files (x86)\JAM Software\Exchange Server Toolbox\bin\ESTAgentExchange.exe" /install (Pre 6.0 ESTAgentNet4.exe /install)

First check if the Add-In is listed under Options/Add-ins/Disabled Application Add-ins

  1. If this is the case select "Deactivated Elements" in the combobox below and press "Go".
  2. Remove the Add-In from the list.

Check if the Add-In is inactive

  1. Select "COM-Add-Ins" in the combobox and press "Go".
  2. Activate the Add-In by checking the box next to its name.

ClamAV signatures are updated every time the service is started and automatically every three hours. You can also update the signatures manually in the anti-virus settings.
