A Custom GPT is a saved, reusable, purpose-built version of ChatGPT — with its own instructions, knowledge files, and (optionally) connected actions/tools — that anyone on the team can open and use without re-explaining anything.
Think of it as "hiring" a specialized digital teammate once, instead of re-training ChatGPT every conversation.

You can use a Custom GPT to create an executive brief every morning based on your email and calendar. When building your GPT, look for Outlook and Outlook Calendar in the list of available plugins — connect them, and your GPT can summarise overnight emails, flag urgent items, and preview your day's meetings automatically.
