Using Outlook for iOS for personal email and calendar management
Hi ,
I'm Dyari. Thanks for reaching out. I will be happy to assist you in this regard.
To confirm you are not receiving emails, please check your email from the Outlook Web. If you received emails, the issue is with the Outlook app on your iPhone.
Then, sign in to the OneDrive website or the Microsoft Account Dashboard. On the OneDrive main page, your storage usage and available space are shown in the bottom-left corner or via the Settings > Options.
If it runs out of space, you need to free up some space or purchase more space.
Please keep me posted.
