For many teams, Microsoft 365 is the central mailbox where customer questions come in: order questions, complaints, returns and one-off requests all land in the same inbox. As an example within the email and mailbox category, Microsoft 365 lets you connect your existing business address directly to Cuego, without migrating or switching to a new address.
Once the mailbox is connected, Cuego reads every incoming email, understands the question and acts: Cuego consults your other systems, drafts a reply or performs the action, and sends the answer back from the same Microsoft 365 address. Your team keeps oversight and only steps in where needed.
The context that comes with it
This information already exists somewhere
Cuego doesn't copy your system. This data comes in the moment a customer gets in touch about it, and moves back into the background afterwards.
Incoming emails from your Microsoft 365 mailbox, synced in real time
Outgoing replies, sent from the same address so the customer sees nothing unusual
Full email threads, so the entire conversation history is included as context
Attachments such as invoices, photos and order confirmations the customer sends along
Sender and recipient details to link the email to the right contact
Subject and timestamp, so priority and turnaround time stay visible
The integration in motion
1. The question comes in
Cuego only knows what the message says
A customer gets in touch. At that point Cuego knows nothing beyond what the message says: a name, an address and a question. Everything that makes the answer complete still sits in Microsoft 365.
Question about my order #8124
Questions that answer themselves
With that data in place, nobody has to go looking. This is what can happen next.
Where is my order?
Cuego reads the email, recognizes the order number or contact, looks up the current status in your systems and emails the customer a concrete answer with tracking.
I want to return this
Cuego understands the return request from the email body and any attachment, checks whether it falls within policy and sends back the correct return instructions or label.
Is my invoice correct?
Cuego reads the question and the attached invoice, compares it with the order data and explains line by line what was charged, or escalates neatly to your team.
A new question inside a long thread
Because the whole thread is included as context, Cuego also picks up a follow-up question at the bottom of a long conversation without the customer having to repeat everything.
How it works
How to connect it
In Cuego, go to Integrations, choose Microsoft 365 and sign in with your business account. You grant permission once through the secure Microsoft login, after which Cuego starts syncing the mailbox right away. There's nothing to migrate and you keep your existing address; within minutes Cuego reads and answers new customer email.
FAQ
Frequently asked questions
No. You connect your existing Microsoft 365 mailbox and keep using the same address. Customers email as usual and see no difference; Cuego replies from that same address.
