What file and folder exclusions are created automatically when Symantec Endpoint Protection (SEP) client is installed on a server that runs Microsoft Exchange server or certain Symantec gateway scanning products?
If Microsoft Exchange servers are installed on a computer with Symantec Endpoint Protection client, the client software automatically detects the presence of Exchange. When the client software detects a Microsoft Exchange server, it creates the appropriate file and folder exclusions for File System Auto-Protect and all other scans. Microsoft Exchange servers can include clustered servers. The client software checks for changes in the location of the appropriate Exchange files and folders at regular intervals. If Exchange is installed on a computer where the client software is already installed, the exclusions are created when the client checks for changes. The client excludes both files and folders; if a single file is moved from an excluded folder, the file remains excluded.
The latest available release of the Symantec Endpoint Protection client software creates file and folder scan exclusions for the following Microsoft Exchange server versions:
Symantec recommends that the Exchange server's OS always be protected by the latest available release of SEP. The Exchange server's message flow and Information Store must be protected by a dedicated mail security product, such as Symantec Mail Security for Microsoft Exchange.
For Exchange 2007, 2010, 2013, 2016, see the user documentation for information about compatibility with antivirus software. It may be necessary to create scan exclusions for some Exchange folders manually. For example, cluster servers or non-default locations for folders require specific exclusions. Also, folders that are part of a Database Availability Group (DAG) are not automatically excluded. For more information, see the Microsoft TechNet article Anti-Virus Software in the Operating System on Exchange Servers.
The client also creates appropriate file and folder scan exclusions for the following Symantec products when they are detected:
Symantec Mail Security for Microsoft Exchange (SMSMSE) 4.0, 4.5, 4.6, 5.0, 6.0 and 6.5
Symantec AntiVirus/Filtering 3.0 for Microsoft Exchange
Norton AntiVirus 2.x for Microsoft Exchange
Symantec Endpoint Protection Manager embedded database and logs
Note: To see the exclusions that the client creates, examine the contents of the HKEY_LOCAL_MACHINE\Software\Symantec\Symantec Endpoint Protection\AV\Exclusions registry. Do not edit this registry key directly. Any additional exclusions can be configured by using centralized exceptions.
On a 64 bit server using Exchange 2007, 2010, 2013 or 2016, the path in the registry to confirm auto exclusions is slightly different. The path includes the WOW6432node key.
HKLM\Software\WOW6432node\Symantec\Symantec Endpoint Protection\AV\Exclusions\.

The client does not exclude the system temporary folders from scans because doing so can create a significant security vulnerability on a computer.
If client email applications use a single inbox
The applications that store all email in a single file include Outlook Express, Eudora, Mozilla, and Netscape. If client computers use any email applications that use a single inbox, create a centralized exception to exclude the Inbox file. The exception applies to all antivirus and antispyware scans as well as Auto-Protect.
The Symantec Endpoint Protection client quarantines the entire Inbox and users cannot access their email if the following statements are true:
Symantec does not usually recommend excluding files from scans. When you exclude the Inbox file from scans, the Inbox cannot be quarantined; however, if the client detects a virus when a user opens an email message, it can safely quarantine or delete the message.
