How to Sync Microsoft 365 Email and Calendar on iPhone
Question details
The user needs to restore or set up Microsoft 365 email and calendar synchronization on their iPhone.
- Product
- Microsoft 365
- Device & OS
- iOS
- Scenario
- Setting up or restoring the connection between a Microsoft 365 account and the native iOS Mail and Calendar apps.
- Observed behavior
- Emails or calendar events from Microsoft 365 are failing to appear or update on the iPhone.
Verify that you have an active internet connection and confirm your Microsoft 365 account credentials are correct by logging into your webmail via a browser.
Enable Mail and Calendar Sync in iOS Settings
Use this solution if your account is already added to your iPhone but emails or calendar events have suddenly stopped updating.
Sometimes iOS updates or accidental taps can disable the sync toggles for specific data types within your email account. Re-enabling them will force the iPhone to fetch the latest data from the Microsoft server.
Unlock your iPhone, open the Settings app, scroll down, and tap on 'Mail'. Then tap on 'Accounts'.
Find and tap the account that hosts your primary Microsoft 365 email address (this may be named 'Exchange' or 'Outlook').
Ensure the toggle switches next to 'Mail' and 'Calendars' are turned on (the switch will appear green). If they are already on, turn them off, wait a few seconds, and turn them back on to refresh the connection.
Remove and Re-add the Microsoft 365 Account
If the sync settings are correct but the account is still failing to update, the Exchange connection may need to be recreated.
Install the Latest iOS Updates
Outdated system software can cause compatibility issues with Microsoft Exchange ActiveSync protocols.
Experience a Seamless Mobile Office with WPS Office
While resolving your Microsoft 365 sync issues, consider trying WPS Office for your document needs. It is a lightweight, completely free alternative that allows you to read, edit, and manage Word, Excel, and PowerPoint files directly from your iPhone without subscription barriers.
- 1. Download from App Store: Search for WPS Office in the Apple App Store and install it on your iPhone.
- 2. Open Your Documents: Launch the app to seamlessly open any Word, Excel, or PowerPoint files stored on your device or in the cloud.
- 3. Edit on the Go: Use the powerful mobile editing tools to make changes, add comments, or export files to PDF effortlessly.
Frequently Asked Questions
Why does my iPhone say 'Cannot Get Mail' for my Microsoft 365 account?
This error typically indicates an authentication issue or a disrupted connection to the server. Removing the account from Settings > Mail > Accounts and re-adding it via the 'Microsoft Exchange' setup option usually resolves this.
Are there alternative apps for syncing Microsoft 365 on an iPhone?
Yes. If the native iOS Mail and Calendar apps are not functioning properly, you can download the official Microsoft Outlook app from the App Store, which bypasses iOS settings and connects directly to your Microsoft 365 mailbox.
How long does it take for the iPhone calendar to sync with Microsoft 365?
If your account's 'Fetch New Data' setting is configured to 'Push', calendar events and emails should sync almost instantly. If set to 'Fetch', it will sync according to the interval you set (e.g., every 15 or 30 minutes).
