Outlook Storage Saying it's Full Even Though it's Not.

I've been dealing with this issue since Monday, my email is saying that my storage is full. When I click 'Manage Storage' it shows that my email storage is 0.8 GB of used storage and 100 GB available. My OneDrive storage is 5.5 GB of used storage out of 100 GB. I'm only getting this storage full warning on the Outlook web browser and the Outlook app. I'm not getting any storage full warnings from OneDrive on my computer.

I've tried to reset my account on the Outlook App on Android, I've tried deleting the cache, deleting the data, I've tried uninstalling the app and reinstalling, I've tried logging off and logging back in. NOTHING is working. I've tried resyncing on my computer and looking for sync issues. Because OneDrive isn't getting the warning, there are no issues found.

I've already spoken to multiple people on the Live Chat option with Microsoft; all they tell me is that they can do nothing. I can't delete any emails, if I try to delete emails, it'll just refresh and show the emails still there. I can't send any emails because of the storage full warning. I can receive emails, however, I just cannot respond to them whatsoever.

    You have to delete enough email attachments to bring your used storage under the 5GB free allowance, the new quota will then kick in. It's a terrible bug.

    I have a normal Hotmail account that I have been using for many years, I got an error that states "You're out of storage. You cant send emails, and wont be able to receive them in 17 days."

    I selected manage storage to understand what was taking up the space:

    1.2GB Microsoft storage

    2.4GB Outlook storage

    I thought you got 15GB as standard so I don't understand why I get the message:

    This is what the standard Microsoft account should come with??
    15 GB of mailbox storage

    5 GB of OneDrive storage

    As I am going through a personal challenge in life having access to email is key so I paid for the extra storage 100GB at £19.99 and I still have the same error. Can someone help as contacting Microsoft support is too much of a challenge!!

    I really need this resolved as I cant send emails any more
