Recommendations on Naming Conventions for O365 Groups

The difficulty we are facing with this model for naming policies is that it exploits only attributes of the currently logged-in user, hence an automated procedure won't be able to rely on that (e.g. the "create on behalf of" could be a great feature here ).  

Add the variety of the business needs, e.g. create groups for projects/initiatives, or ad-hoc groups or departmental teams, etc. leads to making use of administrator's exceptions mostly at all times.

So we ended up every time into providing a form enabling collection of a various parameters, that get concatenated to fit the purpose of the customer, curated to escape spaces and other unwanted characters, and ultimately the prefix / suffix are merely used to add small things to match A-AD requirements set by admins.

A most appropriate solution should allow the definition of a formula, e.g. RegEx language, and injection of parameters via a pre-defined syntax to abide by, instead of exploiting user's attributes.
