Your inbox already knows your life — the flight confirmation, the dinner reservation, the Amazon receipt, the utility bill, the birthday party invite. The problem is that this information stays trapped as unread email, so you end up re-reading, re-typing, and re-remembering it all yourself. Yuki fixes that by connecting directly to your Outlook (or Microsoft 365) account and quietly turning those messages into a live calendar, trip itineraries, tracked expenses, delivery updates, and reminders — no forwarding, no copy-paste. This guide walks you through connecting Outlook to Yuki, what to expect once it's linked, and how to troubleshoot if the connection doesn't take.

Before you start: what you need
Connecting Outlook to Yuki takes about two minutes and only requires two things: the Yuki app on your phone and the password to the Microsoft account you want to link. Yuki is free to download on both iOS and Android, with a 30-day free trial (inbox sync is a Pro feature), and the connection is made entirely inside the app — there's no standalone web app to sign into.
Yuki works with personal Outlook.com and Hotmail addresses as well as Microsoft 365 / work-and-school accounts. If your work account is managed by an IT admin, some organizations restrict which apps can connect; if you hit a wall there, a personal inbox is the fastest way to try it out.
- The Yuki app (iOS or Android) — the only place you can connect an inbox
- Your Microsoft / Outlook account credentials
- A minute for the first sync to read recent messages
Connecting your Outlook account, step by step
During onboarding Yuki will prompt you to connect an inbox. Choose the Outlook / Microsoft option and you'll be handed to Microsoft's own secure sign-in screen — you enter your password with Microsoft, not with Yuki, so your credentials are never typed into the app itself.
After you sign in, Microsoft shows a consent screen listing the read access Yuki needs to scan your confirmations, receipts, and invites. Approving it completes the link and kicks off the first sync. If you skipped this during onboarding, you can connect anytime from your profile's email settings.
- Pick Outlook / Microsoft from the connect-email screen
- Authenticate in Microsoft's secure window
- Approve the requested read permissions
- Let the first sync finish to populate your data
What happens after Outlook is connected
Once linked, Yuki reads the useful signals in your inbox and organizes them for you. Flight and hotel confirmations become trip itineraries, calendar events write two-way to Google Calendar (Apple Calendar write is available on iOS), receipts and bills become tracked expenses and subscriptions, shipping emails become live delivery tracking, and invites and birthdays become reminders. The everyday email you'd otherwise have to remember to act on turns into a plan you can actually see.
This is where the real payoff lands: instead of you being the system that remembers everything, Yuki becomes the memory-and-coordination layer. If you share a household, you can drop any of it into shared groups for a partner, family, co-parent, or roommate — including splitting bills and settling up — so nobody has to be the family's human calendar.
- A live calendar, trip itineraries, and delivery tracking
- Tracked expenses, subscriptions, and bill reminders
- Shared groups for couples, families, co-parents, and roommates
- Yuki AI to ask questions in plain language
Troubleshooting a connection that won't stick
If the Microsoft window closes without connecting, the most common causes are a cancelled consent screen, a work account that your IT admin has locked down, or being signed into a different Microsoft account than the one you intended. Re-run the connect flow from your profile and double-check which account is shown at the top of the Microsoft login.
If Outlook connects but you don't see events or expenses right away, give the first sync a moment — Yuki reads recent history, and older or unusually formatted emails can take longer to appear. You can also connect more than one inbox, so a work Outlook and a personal Gmail can both feed the same organized view.
- Cancelled or partially approved consent — retry and approve all read permissions
- Locked-down work account — try a personal Outlook to test, or ask your admin
- Wrong account signed in — verify the address on Microsoft's screen
- Nothing showing yet — wait for the first sync, then pull to refresh
Step by step
- 1Download Yuki (free) from the App Store or Google Play and open it — connecting email happens in the mobile app, since there is no separate web version.
- 2Create your account or sign in. You can start with Google, Apple, or email/password; you don't need an Outlook login just to make the account.
- 3From onboarding tap 'Connect email' — or later, go to Profile and open your email connection settings — and choose Outlook / Microsoft.
- 4Sign in to your Microsoft account in the secure Microsoft window that appears (this is Microsoft's own login, not Yuki's).
- 5Review and approve the read permissions Yuki requests so it can scan incoming confirmations, receipts, and invites.
- 6Wait for the first sync to finish — Yuki reads recent messages and starts populating your calendar, expenses, trips, and reminders automatically.
- 7Optionally connect a second inbox (for example a personal Gmail alongside a work Outlook) so everything lands in one place.
