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\Jam.EST.Exchange.Agent.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.

The "Exchange Server Toolbox" considers all user mailboxes on the exchange server but without room and device mailboxes.
In the configuration interface under Licensing you can see which and how many mailboxes the "Exchange Server Toolbox" uses for licensing.

There you can also exclude individual mailboxes from processing and thus from licensing.

In this case the Exchange Server Toolbox will start sending notification mail to administrator accounts and after some time it will stop processing rules including anti-spam and anti-virus rules.

The number of mailboxes available AND installations per Exchange Server are depending on your "Exchange Server Toolbox" license.
There are licenses that reach from up to 10 mailboxes up to an unlimited amount of mailboxes.

There are 2 possible reasons why "Demo version" still shows up:
1. You did not download and install the full version from the URL you received after the purchase.
2. You have accidentally installed the trial version again. (Have you been asked for a license key?)

The "Exchange Server Toolbox" uses .Net regular expressions with the options IgnoreCase and Singleline set to true.

A tool for testing .NET regular expressions can be found here:

When the Exchange Server Toolbox tries to send auto reply messages, it uses the Exchange Server to send these mails over SMTP. Since by default the Exchange Server rights are restricted, the Exchange Server Toolbox may not be allowed to do this. Therefore you have to configure your Exchange Server to allow the Exchange Server Toolbox (i.e. localhost) to send mails via Port 25 or 587.
