  1. Is this your corporate iPhone? Then please contact the system administrator of your corporate
  2. If it is your personal device, in that case, do you have any profile installed by your corporate/organisation/enterprise/School Management?
    1. Erase the profile added by you If you have installed a profile on your own --> Install or remove configuration profiles on iPhone - Apple ...
    2. Or please contact the system administrator of the organisation who provided the profile to you


When a corporate profile (like a Mobile Device Management or MDM profile) is installed on an iPhone, it can control various parts of the device, including iCloud settings — but it depends on what the company has configured in that profile.


If the MDM profile enforces certain restrictions — like disabling iCloud Drive, iCloud Photos, or iCloud Keychain — those features might get turned off. In that case, data tied to those services (like photos, documents, or app data) won’t be deleted from iCloud itself, but they will be removed from the local device until the restriction is lifted.


However, if the corporate profile removes or signs you out of your iCloud Apple ID entirely, that could lead to more significant data loss on the device — like contacts, calendars, and notes if they were syncing through iCloud. Again, that data would still exist in iCloud (unless specifically wiped remotely), but it would disappear from the phone.


One big thing to watch out for: some corporate profiles can include remote management capabilities, which could let the company wipe the device entirely, including iCloud-related content.


So the loss of data on the device is possible — but whether it’s also removed from iCloud depends on the specific policies set up in the MDM profile and the actions the company takes.
