The myth of "adobe.com" is safe is being repeated far too much. Anyone can send fake email from any email address at all. So receiving an email from trustedsource@adobe.com means NOTHING AT ALL. `Of course people want an easy way to detect fakes but it is very bad to keep repeating this myth. It no more proves it is from Adobe, that receiving a letter with an address written at the top proves it is from that address.
You need to look into the mail headers. Spoofing e-mail addresses is possible, however, all major mail gateways are asking for confirmation that the mailserver is genuine, which respricts the spoofing possibilities. But the headers really show what happened.
The only way to know for sure is to get confirmation from Adobe (@iCharles ) that this person exists inside the Adobe universe.

If what has been told in the mail is true (that you tried to add Acrobat licences and that failed), contact Adobe support via the admin console (https://adminconsole.adobe.com/support) and let them help you.
Scam and spam mails do not use the adobe.com domain, but it is possible to give you the impression of such a mail address. When analysing the mail header or the mail source file, you will detect such message spoofing. In addition, most mail servers nowadays try to check if the mail server is authentic.
As a side note: it is good to be sceptical. I never click links in mails, when I'm not 100% sure that the mail comes from a confirmed source.
