Configure the quarantine directories on the Microsoft Exchange Server. The quarantine directory will be excluded from scanning.
Quarantine directories are file-based and do not reside on the Information Store.
The Messaging Security Agent quarantines email messages according to configured actions. The following are the quarantine directories:
- Antivirus: Quarantines email messages containing virus/malware, spyware/grayware, worms, Trojans, and other malicious threats. 
- Anti-spam: Quarantines spam and phishing email. 
- Attachment blocking: Quarantines email messages containing restricted attachments. 
- Content filtering: Quarantines email messages containing restricted content. 
By default, all directories have the same paths (<Messaging Security Agent installation folder>\storage\quarantine). You can change the paths for each or all of the directories.
