when I remember correctly, we had similar problems with release or delete messages.
We also use Notes and with set the options "Add the digest as an email attachment" and "HTTP POST" all works fine
When you not set "add the digest..." you see "Note that many email clients do not support interactive HTML digests correctly".
Maybe Notes do something with the embedded content. The digest as attachment works fine.
Thanks for your response
We found out is the URLs generated by MEG and sent to end user were using port 10443. Since most of our offices around the globe don't have this outbound port opened by default we were seeing this issue. See the URL belw.
McaFee solution was to uprade from MEG 7.5 to 7.6.1.
MEG 7.6.1 does the communication over standard port 443, which is opened by default since it is a "official" web browser port. So the URL above now looks like:
That was the case for both cases: "Add the digest email as an attachment" selected or not selected. In another words it was failing for both configs on 7.5.1 and it is now working for both selection on 7.6.1
I hope this helps.
Have a great day! Adalton
