Help "Show pictures" functionality doesn't work in my corporative mail account

[bsimeonov2000]

Hi,
I have a corporative mail account, added by the default mail client coming with my Nexus.
The problem: I noticed that when I receive an e-mail with some pictures embedded I can not see them. Even if I press "Show pictures", I still see some white boxes with blue question marks instead of the pictures embedded. However I could see the pictures as files attached to the mail, but if I receive several pics emebedded in 1 mail, then I have to click several times to see them, instead to see all pictures at once within the mail.

Could you please help me?
Thank you in advance!
