Error code 80090034 was generated when attempting to add a new Office 365 email account into Microsoft Outlook stating that your computer's trusted platform module has malfunctioned. Something went wrong - doesn't it always!

We had performed a fresh installation of Windows 11 including the installation of Office 365. We then performed a sysprep after which we took an image of the machine using Macrium Reflect. Following this, we continued to setup via the out of box experience.
Don't worry if you don't understand what this means, it may not be important to your scenario.
On creating the new user, we proceeded to set up their Outlook mailbox and the error was thrown.
Regedit.exe and click OKHKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297ebThe error message stated that TPM encryption had failed.
