Spreadsheets embedded in word docs are not True-Typed as "Spreadsheet Document"
Last Updated May 16, 2019
When extracting a spreadsheet embedded within a MS Word document, Messaging Gateway (SMG) 10.7 does not True-Type the embedded spreadsheet data as the file type "Spreadsheet Document".
This may cause some custom Content Filtering rules to not properly fire on messages which contain Word doc attachments with embedded spreadsheet data if the Content Filtering rule is looking for the "Spreadsheet Document" attachment type but does not otherwise affect scanning of the attachment for malware.
Similarly, Disarm policies which have exempted Word documents but not spreadsheets from Disarm scanning may not take appropriate action on the embedded spreadsheet data.
This is a known issue and will be addressed with a future release.
The failure to True-Type embedded spreadsheet data does not effect scanning of attachments for malware.
