No.
For Microsoft Apps, you’ll need to download the individual Apps (e.g., Outlook, Word, Excel etc.) from the Apple App Store - and you’ll need an active Office 365 Subscription.
Without an O365 Subscription, for devices with a screen exceeding 10.1”, the MS Apps are limited to opening and viewing existing documents only. With an active subscription, full App functionality is enabled.
