Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi, @Prince Sehgal
What is the full error message displayed when you try to sign in? Does it say that the purchase was successful but Microsoft couldn't associate it with your Microsoft account?
Since you purchased Microsoft 365 through the Apple App Store, Apple manages the subscription billing and renewal. This is why it may not appear as a Microsoft-billed subscription under your Microsoft account.
In the meantime, try restoring your purchase:
- First, confirm that Microsoft 365 is listed as an active subscription under your iPhone's "Settings" > your name > "Subscriptions".
- Open the same Microsoft app you used when making the purchase.
- Sign out of the app and close it completely.
- Reopen the app and look for "Restore previous purchase" at the bottom of the Get Started screen.
- Follow the prompts and sign in with the Microsoft account you used when making the purchase.
You can find Microsoft's instructions here:
If the purchase still cannot be associated with your Microsoft account, contact Microsoft Support for assistance with the account association. Apple Support can also help investigate the App Store purchase if the restore process cannot verify it.
