What you’re seeing
- Work email arrives in iPhone Mail, but no work events appear in the built-in Calendar app.
- Only some work events appear, or events from the past few weeks are missing.
- The work calendar is listed but greyed out or unchecked in Calendar.
- Changes made on the iPhone do not appear in Outlook on the computer.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Calendar sync is turned off for the Exchange account in iPhone settings.
- The calendar sync range is limited to a short period, such as two weeks.
- The account was added as IMAP rather than Exchange, which does not include calendar.
- Conditional Access or Intune policies only allow work data in the Outlook app, blocking the built-in Calendar.
- Shared or delegated calendars are not supported by the native iPhone Calendar the same way as in Outlook.
- A sync issue on the iPhone requires the account to be refreshed.
Why it matters
Many small business owners prefer the built-in iPhone Calendar to see work and personal appointments together. When work events do not appear, they miss meetings, double-book and lose track of their day. Because email still works, the problem can go unnoticed until something important is missed. It also leads people to manually copy events into personal calendars, which risks leaking client information.

Frequently asked questions
Why does email work but not calendar?
Email and calendar sync separately. The account might be set up in a way that only includes mail, or calendar sync might be switched off or blocked by policy.
Should we just use the Outlook app instead?
That works well for many teams, but if your policies allow it, the built-in Calendar can be made to work too.
Who can set the work calendar up on our iPhones?
A certified US engineer can review your phone and Microsoft 365 setup in a remote secure session, from $99, and you pay only when resolved.
