I use my Galaxy S3 for both work and personal email messaging. I use gmail for personal and the stock email application, synced to Microsoft Exchange, for work email.
However, when I compose an email in the stock email application, it sometimes autocompletes with an address from gmail. This is very irritating (and has resulted in some mis-sent emails), and I want to disable it entirely. I do not want to see ANY addresses from my "Gmail Contacts" in the stock email app. I only want to see suggested emails from my Exchange contacts. Possible?
Also, in the meantime I have enabled the "delayed send" feature to remind myself to check email addresses before sending.
