Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have discussed your situation with other senior engineers.
We found that the OneDrive in your screenshot does not appear to be a personal user's OneDrive, as a personal user's OneDrive is not black-themed.
We tested this as a clue and we shared a folder from a corporate OneDrive to a personal OneDrive. The result was that first I would get an alert that the share was successful, but it would be due to the corporate domain control restrictions that the file wasn't actually shared, and the receiving personal account didn't get any alerts either.
So, if this is the case, then this is by design. I would suggest you to contact the corporate IT administrator. Thank you for your understanding.
