[AC Question]

I have a laptop, ipad and note 4. I like to sync them together and have been using gmail. However when I put in a diary event the email confirm or ? goes to my gmail account. I made a new account that had my work email address on it, and have done something silly as its not quite working right.
Can someone tell me how to have one gmail account, with contacts, calendar and emails (i have two email accounts - work and home and neither gmail) syncing please but most importantly, when I set up a group meeting, I need to get the email response back to my work account.
Thanks
