Unable to locate Tasks in sent item

I’ve moved to em after using outlook for a long time and I need help. In outlook whenever I would send emails, I’d assign tasks as follow up reminder for next week or week after that and so on. This follow up would be shown as a flag next to the email in the sent items folder. 

Now in em I’m unable to create follow up/tasks before ending the email, I have to do it after I send them. Also the tasks that I create are not indicated on the email header or in any other way. Please help in locating the tasks and creating follow ups. 

As you have discovered, that is not possible before sending. You can flag or categorize the message before sending, but not create a task from it.

Creating a task from a sent message does not add the message to Tasks. It just creates a new task using details from the message. The two are not linked.
