Ownership transfer of your employees forms

This is just one small part of a pervasive failure in Microsoft's 365 offerings. How many times do you think an employee leaves an organisation and is directly replaced by a new recruit? Now, I have never been able to find a single official Microsoft document that covers what you have to do to ensure every piece of the web of a person's existence, throughout the entire 365 ecosystem is reallocated to the new recruit. There are a myriad of threads across as many fora for pont solutions, such as moving their mail, OneDrive documents etc. But none yet covers everything and a significant number contradict, are out of date or are simply incorrect. Microsoft documentation needs to cover real life scenarios for its customers, detailing precisely what needs to happen for each of the most common scenarios. Such as, a new employee, moving employee, leaving employee, promoted employee. With point instructions for each of the many 365 products. Each time one of these events occurs there are multiple points of contact for the entity, reaching out through the web of Microsoft products and normally this just ends up getting things tied in terrible knots or valuable data simply disappearing into the rest of the organisational amnesia that occurs when people move within or leave a company.
