Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
The block, although it is mentioned in the support document that 24 hours might be taken, it sometimes take 48 hours. How long have you been seeing this?

If you receive the message “Your account is currently unavailable" when you try to access your OneDrive, your account might have been temporarily blocked due to unusually large traffic volume, suspicious activity, or a violation of the Microsoft Services Agreement or code of conduct.
Note
If you recently verified your Microsoft account by entering a security code that you received as a text message, or if you shared a large number of files, the block will be removed within 24 hours.
To check your account status or reactivate your account, go to the Microsoft services account reset page page and follow the on-screen instructions.
I look forward to hearing from you to get the results of the troubleshooting.
