Is it possible to view the login history for office 365? It looks like the consumer version of outlook has this but i can't find anything like that on 365
Login history can be searched through Office 365 Security & Compliance Center . In the left pane, click Search & investigation , and then click Audit log search . Please notice that for User activity in Exchange Online (Exchange mailbox audit logging) you need to have mailbox audit logging turned on for each user. Please see Technet article Enable mailbox auditing in Office 365 .
Office 365 Admin center Home > Usage > Email activity only shows the last activity time of every user and it doesn't report login failures.
If you have concerns about unauthorized logins, you could improve your security by setting up multi-factor authentication for your users. I recommend this at least to those users who have administrative roles
