We have recently had a C405 and two C7020 that have had the Email icon disappear after upgrading to the latest current software.
We can bring it back by resetting the devices back to factory defaults, this is a major issue.
Just in addition to this, I tested turning off https on the device and this gave us something.
When HTTPS is turned off, the screen is still the same, no email button: see pic 1
However when you now go into customise, the email button is there: see pic 2
Unfortunately when you go to the home screen the mail icon does not come back.
As ever, any assistance appreciated.
