    Hi, Joseph Brownfield

    This usually happens when the contacts edited on the laptop are stored under the Gmail contact list or a local Outlook data file, rather than the Microsoft account that the iPhone is displaying. Outlook mobile does not currently support contact sync for Gmail accounts.

    Besides the solutions provided by the Q&A Assist, here are some suggestions you can try:

    Sign in to Outlook People using the same Microsoft account and check whether the updated contact appears there. If it does not, open Outlook on the laptop, select People, and confirm which account or Contacts folder contains it. Contacts saved only in a local folder will not reach the phone.

    On the iPhone, open Contacts, select Lists in the upper-left corner, and make sure the Outlook or Microsoft contact list is selected. The contact may already be synced but hidden because only the Gmail list is displayed.

    Open Outlook on the iPhone and leave it running in the foreground for several minutes, preferably while the phone is charging. iOS may pause contact exporting in the background, so synchronization sometimes does not finish until Outlook remains open.

    If the updated contact appears online but still not on the iPhone, use Help & Feedback > Contact Support inside the Outlook app.

    If the iPhone account is added as IMAP or POP, contacts and calendar will not fully sync. IMAP and POP sync email only. For contacts and calendar to sync, the account must be added as an Exchange/Exchange ActiveSync account.

    Because mail and calendar are syncing but Outlook contact changes from the laptop are not appearing on the iPhone, check these items:

    1. On the iPhone, open Settings > Accounts & Passwords and select the account.
      • On iOS 10, use Settings > Mail > Accounts.
      • Make sure Contacts is enabled.
    2. Verify the account type.
      • If the account is shown as IMAP, remove it and add it again as Exchange.
      • If the account was added incorrectly as IMAP, contacts will not sync.
    3. If using the Outlook mobile app instead of the iPhone Contacts app:
      • In Outlook, go to Settings > tap the account > make sure Sync Contacts is enabled.
      • On iPhone, open Settings > scroll down to Outlook > make sure Contacts and Background App Refresh are turned on.
    4. If the account is in the Outlook app and still not syncing:
      • Go to Outlook > Settings > tap the account > Reset Account.
      • If that does not help, delete the account from the app and add it again.
    5. If contacts were imported from another connected account, those imported contacts may not sync across devices and apps. Contacts created in People can sync, but imported contacts may not.

    If the iPhone is using the Gmail app or a Gmail-configured account path, the key requirement is still that the mailbox be configured with a sync method that supports contacts, not IMAP/POP.
