AI agents for Outlook
A Monmo agent works in Outlook the way an executive assistant would. It triages the day's mail with flags and categories, writes replies the way you would, answers meeting invitations against your calendar and follows up when a message meets silence. It works in your own mailbox, and nothing is sent, accepted or moved until you say so.

What agents do in Outlook
Triage the inbox with flags and categories
At 8:00 each weekday it reads the inbox, Focused and Other alike, since the evening before and proposes the day: six messages to flag for today, four to mark Waiting, the rest to file. One approval applies them.
AskAt 8:00 on weekdays, triage my Outlook inbox: which messages to flag for today, which are waiting on others and which to file. Apply nothing until I approve.
Draft replies that fit the recipient
It writes differently to a client, a supplier and a colleague, using how you have answered each of them before, and checks who should stay on copy before a reply-all. You edit the draft, then allow the send.
AskDraft answers to today's flagged messages: formal for the two client emails, brief for colleagues. Tell me before you reply to all.
Answer meeting invitations
It checks each invitation against your calendar and your rules, such as no meetings before 10:00 or on Friday afternoons, and proposes accept, tentative, decline or a new time. Nothing is answered until you allow it.
AskGo through my pending meeting invitations. Suggest accept, decline or a new time for each, and point out any clashes.
Follow up when nobody answers
It keeps a Waiting list of the questions you sent: who owes you an answer and how many working days have passed. On day three it writes a two-line reminder for each, and you pick the ones to send.
AskKeep a list of emails where I am waiting for an answer. After three working days, write a two-line reminder and show it to me.
Forward a message with the context attached
When a message belongs with a colleague, it drafts the forward with three lines on top: what is being asked, what you already know and what you need back. Your colleague can act without reading the whole conversation.
AskForward the supplier's price change email to Tom with a three-line summary, and ask him for a view by Thursday.
Get the mailbox ready before you go on leave
Before a week away it drafts your automatic reply with the dates and who to contact, lists the conversations still open and proposes which meetings to decline or move. Each of those changes waits for your approval.
AskI am on leave from 17 to 24 November. Draft my automatic reply, list what is still open and suggest which meetings to decline.
Keep folders, categories and rules in order
It proposes a few folders and colour categories, such as Clients, Invoices and To read, and a rule for mail that arrives every day, like system reports. Nothing is moved, categorised or created until you approve the list.
AskSuggest folders, categories and rules for my inbox, and show me where the last 200 emails would go.
How it connects
- 1The mailbox is your own, connected once: a Microsoft 365 work mailbox or a personal Outlook.com one. The agent reads and writes only as that mailbox.
- 2Mail is private, so choose with care who gets it. One agent is usually enough, such as your Chief of Staff; an agent you have not chosen cannot open the mailbox.
- 3The agent reads mail and the calendar without asking. Sending, answering an invitation, flagging, moving mail or creating a rule always waits for your approval, and one card can carry a morning's replies.

Questions people ask
Can an AI agent read and reply to my Outlook email?
It reads and drafts on its own, and it sends only when you allow it. A Monmo agent goes through new mail on the schedule you agree, proposes what to flag and file, writes the replies and prepares answers to meeting invitations. What to say in a difficult message, and who gets your time, remain your decisions.
Does an AI agent work with a Microsoft 365 work account?
Yes, if your organisation allows the connection. Work and school mailboxes are managed by an administrator, who may need to approve the app once before you can sign in. Personal Outlook.com accounts connect with your own sign-in. For anything the connection does not cover, the agent can open Outlook on the web in its own browser.
Do emails the agent sends come from my own Outlook address?
Yes. The agent works as the mailbox you connected, so an approved reply goes from your address and the answer comes back to you. Nothing is sent before you approve it: a card shows the message, the recipients and the reason, and several routine replies can share one card, each open to edit.
Can an AI agent accept or decline meetings for me?
It prepares the answer and sends it once you approve. The agent compares each invitation with your calendar and the preferences you have given it, then recommends accept, tentative, decline or another time, with the reason. Routine ones can be approved together. Invitations from new people, or for large blocks of time, are raised one by one.
