Which folders do I need to exclude in my virus scanner and other security programs for Exchange Server Toolbox to work properly?
The following folders should be excluded in any external security program to prevent problems with the Exchange Server Toolbox:
This is important so that the Exchange Server Toolbox can check mails for viruses without interference. Since the Exchange Server Toolbox receives emails via TCP and temporarily stores them locally for virus scanning, the processes in the listed folders must be undisturbed during these operations. If security software interferes with the process, errors may occur during email processing.
In addition, it can happen that virus signatures used by ClamAV are detected as viruses. If something deletes or blocks the signatures, the Exchange Server Toolbox cannot provide virus protection.
For more information about using Exchange Server Toolbox and an external virus scanner at the same time, see the chapter Anti Virus in the help.
