Outlook in chat
With an Outlook connection, the assistant works with your emails and your calendar. It searches, summarises and drafts replies. Custodos never sends emails, and sends invitations only after you confirm.

What the assistant can do with Outlook
You need the Outlook (mail & calendar) connection in your account settings, see Connected accounts. Then simply ask in the chat, for example for a client's emails from last week or for free slots on Thursday.
| Task | What happens | Is anything sent? |
|---|---|---|
| Search emails | Searches subject, sender and content, or lists the latest emails. | no |
| Read emails | Reads the text of emails, including the names of attachments. For long emails, only an excerpt. | no |
| Read the calendar | Shows events in a date range, by default from today to seven days ahead. | no |
| Draft a reply or a new email | Saves a draft in your Outlook. A reply stays in the thread of the original email. | no, never |
| Add your own event | Adds an event without attendees straight to your calendar. | no |
| Event with attendees | Shows a proposal for you to confirm. Only your click creates the event. | yes, the invitations, but only after you confirm |
Custodos never sends emails
Custodos does not even ask Microsoft for the permission to send emails. The assistant can therefore only save drafts. You open the draft in Outlook, check it and send it yourself.
If your workspace's data protection replaces names or addresses in the chat with placeholders, Custodos puts the real values back when it saves the draft. The draft therefore contains the original details.
Having a draft written
- 1
Give the task
In the chat, ask for example for a reply to a client's latest email that accepts the proposed date. - 2
Let it work
Custodos shows Searching e-mails…, Reading e-mails… and Writing an e-mail draft…. The finished reply carries Outlook consulted. - 3
Open the draft
The assistant points you to the draft with a link. It is in the drafts folder of your Outlook. - 4
Check and send
Check the recipients and the text in Outlook and send the draft from there.
Events and invitations
An event just for you is added straight to your calendar when you explicitly ask for it. Nobody is invited. The assistant reads times as Central European Time (CET, CEST in summer) unless you say otherwise.
If other people are to be invited, the assistant creates nothing and shows the card Confirm meeting invitation instead. It lists everyone invited under Invitations to: and the text under Message to the invitees:. Only Create & send invitations makes Outlook create the event and send the invitations from your account. The card then shows Event created, invitations sent. and Open in Outlook.
Limits
- Per reply, the assistant creates at most three drafts or events.
- Per reply, it reads only a limited number of emails, and only an excerpt of long ones.
- It only reaches your own mailbox and your own calendar, never those of colleagues.
- Email text passes the same data protection checks as an attachment. Depending on the workspace setting, Custodos replaces personal data with placeholders or does not process the email. More under Personal data.
Attaching emails or adding them to Company Brain
To attach a single email or one of its attachments to a chat, use the Add menu in the message field, entry Outlook (mail & calendar). The same rules apply as for other attachments.
If an email should stay available as knowledge, import it into a brain: under Add sources choose Outlook (mail & calendar), then Import message text or individual Attachments. Details under Cloud imports.
