Who I have the same questioned this topic

Just purchased an LG V30 3 days ago. I have an outlook email address and if I use it to synch contacts, email, calendar dates, etc.. I continuously receive a push notification from the OS saying "exchange is using battery". I have tried disabling and automatic synchronization and have even reset the phone. When I use it through the gmail app there is no problem. However I need my outlook address to synch with my phone for calendar dates etc. Any help?
