It depends on how you feel about tracking: Microsoft Outlook declares data used to track you. The sensitive items are location, contacts and user content. In total the label lists 8 data types; 36% of authenticator apps we checked declare tracking.

Microsoft Outlook's developer reports using usage data to track you across other companies' apps and websites.
Did Microsoft Outlook ask for something?
Pick the permission prompt you saw. We compare it with what Microsoft Outlook's developer declared.
Microsoft Outlook lists Location on its label. Choose While Using and turn off Precise Location if the feature works without it.
Microsoft Outlook lists User Content on its label, linked to you. Choose Limited Access and pick only the photos you want to share.
Microsoft Outlook lists Contacts on its label, linked to you. Limited Access shares selected contacts instead of your whole address book.
Microsoft Outlook declares data used to track you, so expect the “Allow to track?” prompt. Tap Ask App Not to Track; the app must keep working without it.
Health & Fitness is not on Microsoft Outlook's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
A permission is what the app can reach on your iPhone; the label is what the developer says leaves it. They answer different questions.
What Microsoft Outlook collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| LocationSensitiveNot linked to you | Where your phone is, either precisely (street level) or approximately (city or area). | Settings › Privacy & Security › Location Services: choose Never or While Using, and turn off Precise Location if the app does not need it. |
| ContactsSensitiveLinked to you | The people in your address book or social graph. | Settings › Privacy & Security › Contacts: choose Limited Access to share only selected people, or None. |
| User ContentSensitiveLinked to you | Messages, photos, videos, audio recordings, documents and support chats you create or upload. | Settings › Privacy & Security › Photos: choose Limited Access or None; review Microphone and Files access too. |
| Search HistoryLinked to you | Searches you run inside the app. | Look for a clear-history or private-search option in the app. |
| Contact InfoLinked to you | Your name, email address, phone number or postal address. | Use Sign in with Apple with Hide My Email where offered, and check the app's account and marketing preferences. |
| IdentifiersLinked to you | An account ID, screen name, customer number or a device-level ID such as the advertising identifier. | Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted. |
| Usage DataUsed to track youLinked to you | What you tap, open and view inside the app, plus which ads you have seen. | There is no single iOS switch. Look for an analytics or personalised-ads toggle in the app's own settings. |
| DiagnosticsLinked to you | Crash logs, launch times, hang rates and energy use. | Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate. |
What Microsoft Outlook's label means for you
Microsoft Outlook's label has 1 type under “Data Used to Track You”, 7 types under “Data Linked to You”, 1 type under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.
Tracking is the declaration that most separates apps. It means usage data from Microsoft Outlook can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.
The items that deserve the most attention are location, contacts and user content. Location history reveals home, work and routines. Precise location deserves the most scrutiny.
Authenticator apps generate the second factor for your logins. The biggest practical risk is not data collection but losing your codes when you lose your phone. Turn on encrypted backup or export your accounts, and save the recovery codes each service gave you.
Among the 173 authenticator apps in our snapshot with a label, 36% declare tracking, 45% collect data linked to you and 40% say they collect nothing. Microsoft Outlook lists 8 data types, more than the average of 1.8 for this group.
Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.
Settings to check for Microsoft Outlook
- 1
Tracking
Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.
- 2
Location
Settings › Privacy & Security › Location Services › Microsoft Outlook. Choose While Using or Never, and switch off Precise Location if a city-level answer is enough.
- 3
Photos
Settings › Privacy & Security › Photos. Limited Access lets you pick exactly which pictures the app can see; Add Photos Only lets it save without reading your library.
- 4
Contacts
Settings › Privacy & Security › Contacts. Limited Access shares only the people you select instead of your whole address book.
- 5
Sign-in
When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.
- 6
Lock the app
On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.
Does Microsoft Outlook track you?
Usage data. Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker.

Lock Microsoft Outlook behind Face ID
- Find Microsoft Outlook on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Microsoft Outlook now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Microsoft Outlook has a passcode of its own. It does not change what the app sends to its developer.

What the label cannot tell you
- A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Microsoft Outlook sends.
- It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
- Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
- Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
- Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
The question to ask Microsoft Outlook's developer: If this iPhone is lost, how do I restore my codes?
