Edits / Update to Content

There is perhaps something going with Mimecast that I do not understand.

I suspected a domain lock or other permission error.

Seems that this might not be the case.

The solution seems to hinge on signing into Mimecast and releasing the On-Hold message(s).

OR

Inspecting the original message for embedded / unsupported attachments.

HP Support fixed this one - effective but not a solution available for self-help:

Comments - "Anyone" and ePrint Jobs

In my opinion,

Use Caution >> One of the proposed solutions mentioned in the thread:  Open ePrint to "Anyone"

Removing the "access list" (who can send jobs to your printer) means "anyone" who has the printer's address can send jobs to your printer. 

"Can't happen?"  Sure, it can.  Use a silly, easy to guess ePrint printer email address and a spammer might guess the address. 

It is also statistically possible that your neighbors or others might accidently send the printer jobs and never understand why their jobs do not print on their own printer.
