Refuse mail is only available for incoming (recieve) emails. This means that the Exchange Server is currently recieving the email but has yet to accept it. The rule action allows to refuse to accept the email and return an error message to the sender.

Do not deliver mail does not depend on the current status of the email. The rule action will have the Exchange Server quietly discard the email without delivering it.

Incoming (recieve) means that the email is currently incoming and has not yet been processed. It can still be rejected at this point allowing for the rule action "Refuse Mail". This means that your Exchange Server will refuse to accept the email.
Since the emails have not yet been accepted by the Exchange Server they cannot be modified by rules. Any rule to modify the email in any way has to be created in the Incoming (accepted) rules.

Incoming (accepted) means that the email has already been accepted by your Exchange Server. It can no longer be rejected and thus the rule action "Refuse Mail" is no longer available.

This problem is usually caused by the user lacking permissions. You can give the user which runs the Exchange Server Toolbox Service access rights to the folders or you can reinstall the service and create a new user. For the latter solution please refer to this article: https://knowledgebase.jam-software.com/7481

Backups of your blacklist and whitelist settings can be found in the following folder:

C:\Windows\System32\config\systemprofile\.spamassassin\backup

If this folder is empty or does not exist, you can try to restore the user_prefs file from a filesystem backup in one of the following directories:

• C:\Windows\System32\config\systemprofile\.spamassassin\
• C:\Windows\SysWOW64\config\systemprofile\.spamassassin\

This error occurs when the Exchange Server Toolbox could not access the Active Directory. You can manually create the Group Account instead.

1. Open the Active Directory Users and Computers console.
2. In the navigation pane on the left, select the Users container
3. Right-click the Users container, click New, and then click Group
4. In the Group name text box, type ESTMailArchive
5. In the Group scope section, select Global
6. In the Group type section, click Security
7. Click OK to save your group

Members of this group have full archive access rights and can find every email using the archive search.

Please reinstall the Exchange Server Toolbox Service and create a new user during the installation. To do so please follow these steps:

You can find the file ExchangeServerToolboxSetup.exe in the following folder:

C:\Program Files (x86)\JAM Software\Exchange Server Toolbox\bin

To use the argument /force you can start the installation with the command line tool. Start cmd and enter the following commands:

• cd C:\Program Files (x86)\JAM Software\Exchange Server Toolbox\bin
• start ESTInstall.exe /force

Alternatively, you can create a shortcut of ExchangeServerToolboxSetup.exe. Right-click it and add /force at the end of "Target".

Search in C:\ProgramData\Microsoft\Crypto\RSA\ and all subfolders for the following files:

1.     19c988cf76b533f74aaffc201e63f98e_0d5fcf7f-9733-4ba0-a71e-c5b558768432

Please check if the user that should send the error messages is able to use SMTP authentication on the Exchange Server. The connector also needs to be able to access the port 25 TLS.

This problem can be caused by the Windows Defender or other third party anti virus solutions. Add the following paths to the exclusions:

C:\ProgramData\JAM Software\ClamAVInABox\Signatures

C:\Program Files (x86)\Common Files\JAMSoftware\ClamAVInABox\sanesecuritydbtemp

You can find the installation file for the Outlook add-in under

"C:\Program Files (x86)\JAM Software\Exchange Server Toolbox\EstOlAddinSetup-En.msi" 

after installing the Exchange Server Toolbox.
