I'm working on hundreds of different orgs. Some of them have those buttons, other not. How can I get them on all orgs? (In the screenshots see right side in the bottom of each email.)
What have I tried so far?
If, however, the 'Reply,' 'Reply All,' or 'Forward' buttons are not present on the records in the Activity timeline, the 'Send Email' global action may not have been added as a Global Action on the page layout of the the entity in question.
I have a "Send Email" Global Action on the layout. A small difference might be, that I have renamed the out-of-the-box Global Action "Send Email" now having a slightly differen API name elfBCSendEmail instead of just SendEmail.
B) This seems also not to be a solution: "Reply to and Forward Emails Right from Salesforce"
