Yes! We love Office 365 and welcome all your accounts with open arms.
Office 365 accounts can be added to Shift Basic, Pro, and Advanced accounts.
Office 365 email accounts can be added just like your Gmail and other Outlook.com accounts to Shift on the sidebar.
Check out this article to learn how to add accounts to Shift.
At the moment, we don't support Office 365 emails as the primary account in Shift.
All this means is that you can't log into Shift with your Office 365 account.
You will need to choose either a Gmail, G-suite, or Outlook.com account to use as your primary email account.
You will still be able to add your Office 365 account to Shift and use all its features.
Unfortunately, Shift cannot support Exchange email accounts. If your Office 365 account is hosted on private on-premise servers, it won't work in Shift at this time.
If you have OWA, you can try configuring your Exchange email as a custom application in Shift. This article will show you how to add a custom app to Shift.
