Log a Call 
Send an Email 
Request Update

can any one help to achieve this requirement.
Thanks in advance.

A:

This button / action visibility within a Lightning Community is controlled via the Global Publisher layout. If the Email action is not present on the layout then it will not display on the Activity History related list. You can confirm this by going doing the following:
Go to Setup > Global Actions > Publisher Layouts > Global Layout.
Edit the Global Layout.
Locate the Email Mobile & Lightning Action called "Email".
Add this to the Layout.
Save

Clear your browser cache and log back into the Community and access a record where the Send Email action was not present, it should now be restored.
