Currently Microsoft is investigating a problem with the connection between the iOS native Mail application and email accounts using Microsoft email services like the Royal Roads email server.
One possible solution is to simply re-enter the password following these steps:
Please go into Settings → Apps → Mail → Accounts → click on Royalroads account and you should see a warning to re-enter password.
If that process does not solve the problem, try removing and re-adding the RRU email account following the instructions here.
If neither of those solutions solve the issue, you can use the webmail application by logging into Outlook.office.com
Microsoft’s Status page currently says this about the issue (from https://portal.office.com/servicestatus)
