I can't see all the addresses in emails I receive

If you mean all the addresses are not displaying, please note that at the end of the address string there is a a note at the end that states “and other XX people”.  Clicking on this will display all recipients.

If you mean you cannot see the actual addresses, go to menu/tools/settings/mail/read and check :Show email address in email header"

Thanks for this but I still can’t see all the addresses that the email has been sent to

Can you share a screenshot?

That’s not going to help solve the problem.

OK, well then I guess I can’t help
