Hi all,

I've been working on page layouts in LEX for the last week or two.  Yesterday while testing the email action in the activity composer, I started getting the dreaded Insufficient privileges error.  This had never happened before as I have been sending email out of LEX for quite some time.  I tried to send email this morning and everything was fine.  Tried again this afternoon and the error message is back.

The profile settings seem to be fine.

Any ideas?
