I blocked chrome.exe, but not iexplore.exe. And then webmail encrypted attachment to internal recipient with EEFF installed and to my yahoo (iphone). Result:
1. With chrome.exe (blocked):
a. not able to open docx file in iphone --> extension file is docx? (with question mark)
b. Able to read in internal office PC with EEFF, but the padlock symbol is gone and the file is not detected using 'search encrypted' ---> is this known issue?
2. With iE (not blocked):
a. able to open docx file in iphone (decrypted), and in office PC.
This meets my requirement, with little problem on 1.a. Haven't tried with web forum.
I also test to add web browser process to Blocked Process but my internal recipient with EEFF installed and correct key can't open files. The error was "Word found unreadable content in ... ". Did you have the problem open the encrypted file when sending by Web Browser or Email?
