AI for company email and calendar

Ask your AI about your mail and calendar. You stay in control.

    Sound familiar?

    Your people already use AI. You can't see it.

    • Your people already paste company mail into chatbots. You have no log and no say.
    • You want AI for your team, but not a tool that reads everything and sends on its own.
    • Your mail is on Exchange Server, and the big AI assistants are built for the cloud.
    • Your auditor asks who used AI on which mailbox. Today you cannot answer.

    How AddSync AI works: ask, check, look, decide

    Your person asks a question. AddSync checks the rules, the AI reads only the mail it needs, and you decide what happens next.

    What AI can and cannot do in your mailbox

    The AI gets a short list of buttons. Nothing outside the list exists for it.

    Why not just use Copilot or Gemini?

    You should. Where they fit. And where they leave you with nothing.

    On-premises Exchange

    Copilot cannot read your mailboxes. We can.

    Microsoft says it in its own documentation: Copilot is cloud based and has no access to on-premises mailboxes. If your mail lives on Exchange Server, your people get no AI from Microsoft, so they paste your mail into whatever they find.

    AddSync AI works with Exchange Server 2016, 2019 and Subscription Edition, through one service user, your filter and your journal. Your mailboxes stay where they are.

    Questions about AddSync AI

    Is my mail copied? No. Read on request.
    Does AddSync AI copy my mail?

    No. The AI asks for a message when you ask a question, reads it for that answer and does not store it. AddSync keeps a journal of who asked, when and which button, without the text.

    Does it work with Exchange Server on-premises?

    Yes. Exchange Server in your own server room is the case we built it for. It works the same way with Microsoft 365, Outlook.com, Gmail and HCL Domino.

    Can the AI send or delete email?

    No. It can search, show, save a draft and propose. A draft waits in your Outlook until you open it and press Send yourself.

    Which AI tools can I use, Claude or ChatGPT?

    Both. You can connect the assistant your team already uses, or use the chat inside AddSync. AddSync works as the guard in front of either one.

    How do I see who used AI on which mailbox?

    Open the journal. Each line shows the person, the time and the button pressed. Your auditor gets an answer in minutes instead of a week of guessing.

    How long does a pilot take?

    The pilot runs for 14 days. You connect a few mailboxes, your people try real questions and you decide at the end whether to continue.
