Sent Email Activities are No Displayed Anywhere Including Email Log

[HisakoK]

Hi All,
The screen says that "Email Sent" however I cannot find any record of the activities:

I checked the "Email" tab but it does not show the record:

I also checked Email Logs but there is no record of the above email activity:

Could you tell me where I should check to find my emails that the system said "Email sent" but there is no record of them? 

(Or should I get the support from Now Support?)

Thank you in advance.

I hold the admin roll so I don't need to gain any extra access right and so on.

This happened when we use the sample users but when we use the actual team members we do not have that issue.

My team is still investigating the issue and for the workaround we decided to use real members' email addresses. 

So to fix new shared issues now support members also use our team members' email addresses now.
