Microsoft 365

Microsoft 365 is the office suite that most organizations treat as the interchange standard: a .docx or .xlsx opens the same way for the recipient, which is why it remains the safe format for external delivery.

Beyond the applications it bundles mail, cloud storage, Teams and identity management, so for many companies it is the underlying account system rather than just a set of programs.

Excel in particular remains without a real equivalent for complex financial modelling, which is often the single reason a company stays on the suite.
