Attachment Filtering

Attachment Filtering is a feature that scans files attached to email messages, which allows you to control internal and external file exchange within your Exchange Online organization. If Attachment Filtering is enabled, Kaspersky Security for Microsoft Office 365 scans messages for files that match the specified filtering criteria and applies the action that you predefine in the settings.

You can filter attachments based on the following criteria:

• specific file formats;
• specific file names or masks;

  Representation of a file name using wildcards. The standard wildcards used in file masks are * and ?, where * represents any number of any characters and ? stands for any single character.

• presence of macros in Microsoft Office files.

By default, Attachment Filtering is disabled.
