We have bought McAfee DLP and we have installed it in some desktop computers for testing. We have configured all the security in order to avoid users to send Excel documentos to them personal e-mails. The protection works fine with all excel files, in the moment that user tries to upload the Excel document to his Gmail (for example) on the internet explorer, DLP blocks the upload, but the problem is when the excel file size is greater than 20 mb, the protection doesn't work and the excel file is unprotected, the upload to the email ends without any restriction and the e-mail can be sent.
We have tried to find the configuration to allow system to block files grater than 20 mb but we couldnt.
Thanks in advance for your help. I hope somebody knows the solution.
