Connect your Outlook Calendar to InfraNest so renewals, certificate expiries and maintenance windows show up automatically in a dedicated calendar that stays up to date on its own. This is for anyone using Microsoft 365 or Outlook.com who wants their InfraNest schedule visible alongside their regular calendar.

## Overview
- Automatically syncs renewals, certificate expiries and maintenance windows into a dedicated **InfraNest** calendar
- Works with Microsoft 365 and Outlook.com accounts
- Keeps itself current after the first sync — no manual updates needed
- Doesn't touch or change any of your existing calendars

> [!NOTE]
> One-click connecting has to be switched on for your workspace by an administrator first. If it isn't available, the Calendar page will let you know — in that case, use **Subscribe with a calendar feed (iCal)** instead, which needs no setup.

## Connect Outlook Calendar
1. Go to **Integrations** → **Calendar**.
2. Under **Connect your calendar**, select **Connect Outlook Calendar**.
3. Sign in with your Microsoft account and accept the permission request.
4. You're returned to InfraNest, and the first sync starts straight away.

Events go into their own **InfraNest** calendar, so nothing of yours is changed.

> [!NOTE]
> On a work or school account, your organisation may require an administrator to approve the permission request first. If you see a "needs admin approval" message, that's Microsoft asking, not InfraNest.

## Troubleshooting
- **"Reconnect needed"** — Microsoft revoked our access. Select **Connect Outlook Calendar** again.
- **Nothing appears** — make sure the **InfraNest** calendar is ticked in Outlook's calendar list.
