Unscannable File Rule - Quarantining a .pptx document
Hi, First time poster here...
We recently installed "Mail Security for Microsoft Exchange" version 18.104.22.1685, on a Windows SBS 2011 Standard server, and it is working great.
However, I have an internal user, sending a power point to another internal user, and the file is getting Quarantined.
I checked the Event Log for the Event ID 218 description, and see this:
The attachment "Report Writing (Cont’d).pptx" located in message with subject "FW: Power Point", located in SMTP has violated the following policy settings:
Rule: Unscannable File Rule
The following actions were taken on it:
The attachment "Report Writing (Cont’d).pptx" was Quarantined for the following reason(s):
Scan Engine Error. The maximum cumulative file size within a compressed file has been exceeded at location image3.emf within media
How do I fix this problem? Do I somehow stop scanning from one internal user to another?
Can I stop the scanning of compressed files?
Or can I increase the "cumulative file size within a compressed file"? If so, how do I?
Any help would be appreciated. I am very new to the product.
