Consent

Needed in the EU and the UK

MicrosoftApplicationsTelemetryDeviceId is in the Analytics category. In the EU and the UK, analytics cookies need the visitor's consent before they are set. California's CCPA works differently: it lets residents opt out of the sale or sharing of their personal information.

GDPR and ePrivacy (EU): Prior consent is needed before setting MicrosoftApplicationsTelemetryDeviceId. Analytics cookies are not covered by the strictly necessary exemption; only a few regulators (for example France's CNIL) allow a narrow exemption for first-party audience measurement under strict conditions.
UK GDPR and PECR: Consent is needed before setting MicrosoftApplicationsTelemetryDeviceId. The ICO treats analytics cookies as non-essential.
CCPA and CPRA (California): Disclose MicrosoftApplicationsTelemetryDeviceId in your privacy policy and honour opt-out requests, including the Global Privacy Control signal, if the analytics data is shared or sold.

Managing MicrosoftApplicationsTelemetryDeviceId with a consent banner

A consent banner can keep the script that sets MicrosoftApplicationsTelemetryDeviceId waiting until the visitor accepts analytics cookies. Kukie.io's cookie scanner finds MicrosoftApplicationsTelemetryDeviceId and sorts it into a category. The banner holds back known trackers by default, and any other script you tag with its category waits too.
