Cannot open any files or create a new document

Eburgess12 Firstly your Technical Accounts Team should have a direct line to Microsoft. This community forum is not Microsoft support. There are links inside the OneDrive web interface and phone apps to help/support.

If the link didn't work it may be related to your OneDrive problems and should be attempted in a different or incognito browser. Possibly your Technical Accounts team sent you a faulty link. You can also just google for OneDrive support contacts e.g. https://support.microsoft.com/en-us/contactus/#!

Your post does not include basic information 

1. How are you trying to open/create documents? On a desktop computer or phone? From within Office desktop, browser or mobile apps?

2. Have you tried downloading files from the online (browser) OneDrive interface?

3. Have you tried the OneDrive troubleshooter? https://support.microsoft.com/en-au/office/fix-onedrive-sync-problems-0899b115-05f7-45ec-95b2-e4cc8c4670b2
