Also check the file type they are sending. Some systems block certain file extensions, or don'tcan't scan password-protected archives so they bounce the email.

in that case the file extension would not matter as the size limit is more then the restricted by the org.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.
