Cloud Email and Collaboration
Protection searches
for security risks and undesirable data by scanning messages and their attached files
in
email services, files stored in other cloud applications, and messages in private
Teams
chats.
Cloud Email and Collaboration
Protection performs
real-time scans and on-demand (manual) scans. When detecting malicious or undesirable
content, Cloud Email and Collaboration
Protection automatically takes action against the
email message, file, or Teams chat message according to scanning rules. Configure
policies
to scan specific targets and then take certain action or send a notification based
on the
security risk.
NoteManual scan is not applicable for Microsoft Teams (Chat).

By default, Cloud Email and Collaboration
Protection
scans all possible email messages, files, and private Teams chats in the cloud applications
and services it protects. Scannable files include any file that is not encrypted,
password
protected, or exceeds user-configured scanning restrictions.
Real-time scanning and on-demand scanning apply to Advanced Threat Protection policies
and Data
Loss Prevention policies.
Real-time scan
Cloud Email and Collaboration
Protection scans the following in real
time:
-
For email services, scanning occurs when an email message arrives at a protected mailbox.
-
For cloud storage applications, scanning occurs when a user uploads, creates, synchronizes, or modifies a file.
-
For Teams Chat, scanning occurs when a user sends a private chat message.
Manual scan
Cloud Email and Collaboration
Protection provides two manual scan types:
-
Scan and protect: Analyzes email messages or files, and takes action upon detecting any violation triggering the selected policy.
-
Scan only: Analyzes email messages or files, logs the analysis, and delivers the messages or files to users without taking any action configured in the selected policy. This helps evaluate the Cloud Email and Collaboration Protection performance with zero impact on mail flow and file sharing.
Note
This scan type applies to Office 365 services and Gmail only.
Run a manual scan to
ensure that Cloud Email and Collaboration
Protection scans all messages and files.
Completely scanning cloud applications and services in this way minimizes the risk
of advanced
threats or data protection violations. A manual scan affects all users, groups and
sites; however
optionally configure Cloud Email and Collaboration
Protection to scan specific targets, as
needed.
Cloud Email and Collaboration
Protection generates and sends a
comprehensive report after a manual scan to specified users, consolidating the scan
results and displaying detailed information.
Manual scan requirements:
-
For a full license, run a manual scan on up to 31 days of data.
Note
A trial license supports a manual scan only on one day of data, and a manual scan covers 25 mailboxes, 5 SharePoint sites, 5 teams, or 5 cloud application service accounts. -
Run only one manual scan for one kind of policy at a time.For example, you can perform a manual scan for Exchange Data Loss Prevention policies and SharePoint Online Data Loss Prevention policies at the same time. You cannot simultaneously perform two manual scans for Exchange Data Loss Prevention policies.
