attendo + Microsoft 365

The support mailbox stops being just a mailbox: each email is a document with its customer and attachments, and the reply goes out from support@. Plus Outlook appointments and sign-in with your Microsoft account.

What it solves

Five conversations about the same ticket

The support, maintenance or accounts mailbox is where customer requests arrive, and also where they get lost. Nobody knows who replied, answers go out from each person’s own email, and the thread splits.

With Microsoft 365 connected, every incoming email creates or updates a document in attendo, with its customer identified. Replies go out from the document, with the shared mailbox address, and stay on the timeline with their delivery status.

What it does

What it does, piece by piece

Email, appointments and your team’s sign-in, each with the connection it needs.

Personal and shared mailboxes

Through Microsoft Graph or through IMAP and SMTP with OAuth, from one organization or several. For each mailbox you choose which folder is read.

Replies from the right mailbox

A reply from a shared mailbox goes out as that mailbox. You know whether each email was sent, bounced or failed.

Inbound email within seconds

Microsoft notifies attendo when an email arrives and the document is created within seconds. The periodic check keeps running underneath, in case a notification is lost.

Outlook appointments

When you propose an appointment, attendo checks the real availability of people and rooms and creates the event, with the Teams meeting if it is online.

Sign in with Microsoft

Your team signs in with their Microsoft Entra ID account, in the mobile app too, and attendo still asks for their two-factor code if they have it turned on.

Copilot as marIA’s engine

Your organization’s Microsoft 365 Copilot works for marIA, with processing kept inside your Microsoft organization.

Your scheduled documents also show up in Outlook through the calendar subscription, read-only and without connecting anything.

What travels

What travels, and in which direction

Without instant inbound email, attendo checks each mailbox every 5 minutes, or as often as you choose.

Getting started

How to get started

Email and sign-in are set up in Settings with your organization’s credentials. Instant inbound email and Outlook appointments are set up with you, in your Microsoft organization.

Status Available

What you need

Microsoft 365 with Exchange Online
An app registered in Microsoft Entra ID, with its secret and your administrator’s consent
For shared mailboxes, Exchange access for the account that connects them
For instant inbound email, your attendo instance reachable over HTTPS

Typical effort. One or two hours with your Microsoft administrator. What takes longest happens in Microsoft: permissions, consent and access to the shared mailboxes.

Step 1
Entra ID registration

Your administrator registers the app, creates the secret and grants the Graph or IMAP and SMTP permissions. We give them to you in writing.
Step 2
Mailboxes in attendo

You add your organization and connect each mailbox by signing in with Microsoft.
Step 3
Each mailbox, to its queue

Which folder is read, who can send, inbound or outbound, and the flows that turn email into documents.
Step 4
The optional parts

Instant inbound email, sign-in with Microsoft and Outlook appointments, whenever you need them.

Honesty

What it does not do

Personal email
Work mailboxes such as support@ or maintenance@ are connected, not each person’s individual mailbox.
OneDrive and SharePoint
It does not use them for document management: attachments are stored with the document.
Changes made in Outlook
If someone moves the appointment in Outlook, attendo does not pick it up: the appointment is changed from attendo.
Users created from Entra ID
It does not create users or assign roles from Entra ID. Each person must already exist in attendo, with the same email address.

What goes with it

All integrations Every connection, with its real status.

Frequently asked questions

Do we need the Microsoft administrator?

Yes. Only an administrator of your organization can register the app and grant consent to the permissions.

Does it work with shared mailboxes?

Yes, and it is the most common case. It needs the app permission and the person’s access to the mailbox in Exchange.

What happens if the secret expires?

The mailbox stops renewing its access and Settings flags it. A new secret is created in Microsoft and saved in attendo. If someone revokes access, you just reconnect.

Do I lose email if instant inbound email fails?

No. The periodic check keeps running underneath: at worst, it takes as long as it would without it.

Can I have mailboxes from several organizations?

Yes. Each organization is set up separately, with its own credentials and mailboxes.
