+**(85) Why is an identity not available?**
+
+An identity is available for sending a new message or replying or forwarding an existing message only if:
+
+* the identity is set to synchronize (send messages)
+* the associated account is set to synchronize (receive messages)
+* the associated account has a drafts folder
 
+FairEmail will try to select the best identity based on the *to* address of the message replied to / being forwarded.
