an error occurred while sending mail

[exaiming]

Hello.

I get an issue when I press button "Send file as email attachment". An error says  "an error occurred while sending mail".

I want to attach into Outlook. Unfortunately, I have not found a solution on the Internet.

I tried:

1.Checked if outlook is setted as default email. Yes, it is setted.

2.Checked it if is true ( checked in regedit )

3.Checked if the file is not so big(size).

4.Un-ticked the check-box "Enable Enhanced Security" . Still didnt help

5.Checked if in preferences>Email account outlook is setted as default. It is.

I use outlook 2016.

Versions of my Adobe is 11.0.22

Please, really need your help. Trying to find a solution about 1 week.

Thank you.
