If you are installing Kaspersky Security 9.x for Microsoft Exchange Servers on a server, where a third-party antivirus solution for servers is installed or will be installed, we recommend that you exclude the service folder Store (%SystemDrive%\Program Files (x86)\Kaspersky Lab\Kaspersky Security 9.x for Microsoft Exchange Servers\data\store) from the scope of all scan tasks.

This folder contains:

• The temporary objects storage for scanning in RAM.
• A backup storage where Kaspersky Security stores infected objects before disinfecting or deleting them (the objects are stored encrypted).

Transport hub and Edge transport roles of the Microsoft Exchange server allow installing a third-party antivirus solution for side-by-side work with Kaspersky Security 9.x for Microsoft Exchange Servers. It will function along with Kaspersky Security interceptors for these roles. However, this significantly enhances the CPU load and requires complex and thorough configuration of both antivirus products. We recommend that you remove third-party antivirus solutions before installing Kaspersky Security 9.x for Microsoft Exchange Servers.

Kaspersky Security 9.x for Microsoft Exchange Servers  is not compatible with third-party antivirus products for protecting Microsoft Exchange server with a Mailbox role.
