The connection

How does Horizon actually get into Outlook?

Horizon connects through Outlook's official API. Your team approves which records Horizon can use and what it may prepare before the build starts.

What Horizon can see

Approved messages, folders, attachments, categories, contacts, calendars and events in supported cloud mailboxes.

02 · Prepare

What Horizon can prepare

Horizon shows your team email drafts, replies, categories, calendar events and meeting changes for staff review before saving or sending.

03 · Start

How work can start

Outlook can notify Horizon about selected mail and calendar changes, while scheduled checks build follow-up and meeting briefings.

What we confirmed about the Outlook connection

  • Outlook supports primary and shared cloud mailboxes, but not in-place archive mailboxes through this route.
  • Horizon can combine mail, attachments and calendar context into a meeting or follow-up briefing.
  • Drafting can be automated safely while sending and meeting changes remain with the team.

Day to day

Use Outlook without jumping between systems.

Outlook stays in place as the software your team already uses. Your team asks in Teams, Copilot, Claude or ChatGPT, and Horizon answers with only the approved records that request needs.

We connect one workflow first, prove it with your team on real review steps, then expand.

Common questions

Using Horizon with Outlook, answered.

What could our team ask Horizon to do with Outlook?
Find the important conversations, prepare meetings and draft follow-up without manually searching every folder. Typical results include an Outlook follow-up exception list, a meeting briefing from Outlook, and an Outlook action pack ready to approve.
Can our team use Outlook from Microsoft Teams?
Yes, after the agreed access is approved. Your team asks Horizon in Teams, Horizon checks the approved Outlook information and connected systems, then returns the answer or proposed action for review.
Can Horizon use Outlook with Outlook, SharePoint or our other software?
Yes. We design one workflow around Outlook and the other approved systems your team relies on, so the result can use the relevant information without staff opening each system separately.
Can Horizon prepare changes in Outlook, not just answer questions?
Yes, where Outlook supports the agreed action. Horizon prepares the change, shows it to the right person and applies it only under the permissions and review rules agreed for the workflow.
What would we start with in Outlook?
We start with one useful, controlled request such as: @Horizon, show me client emails from the last seven days that still need a reply or clear owner. The first version stays narrow enough to test with real staff and real review steps.
What access is needed before work starts?
A Microsoft 365 user or administrator approves the mailbox and calendar access. Existing mailbox, shared mailbox and calendar permissions continue to apply.
Does Horizon replace Outlook?
No. Outlook remains the system your team uses. Horizon connects only the approved data and actions needed for the agreed workflow.
How does Horizon keep the Outlook workflow safe?
We agree exactly which records, people and actions are in scope. We test one limited workflow with approved examples, keep important changes behind human review and expand only after the pilot is working properly.
The audit costs nothing
