A new AO, Kim Richardson, is taking over duties for Chris West. What function could you use to ensure Kim assumes Chris's duties on the organization's routing lists?

The choice of Globally Replace Signature Authority is the appropriate function for ensuring that Kim Richardson assumes Chris West’s duties on the organization’s routing lists effectively. This function allows the organization to update multiple records or lists uniformly, replacing the previous signature authority with the new one.

By utilizing this option, all routing lists and responsibilities linked to Chris West can be updated in a streamlined manner without the need to adjust each one individually, thereby saving time and minimizing the risk of oversight. This ensures continuity and clarity in the workflow, as all documents or initiatives requiring approval or attention will now be directed to Kim instead of Chris.

In contrast, creating a new signature authority might not automatically transfer the routing responsibilities, while reassigning routing lists individually could prove inefficient and prone to error if not all lists are addressed. Copying Chris's routing responsibilities could lead to duplication or leave some aspects unaccounted for, which is why the global approach is the most effective solution in this situation.
