File size limits for Intranet zone

UserIntune-readyPersistence_FileLimits1

Supported on At least Internet Explorer 5.0

25H2 · 1.0

What it does

Limits the amount of storage that a page or site using the DHTML Persistence behavior can use for the Local Intranet security zone. If you enable this policy, you can specify the persistence storage amount per domain or per document for this security zone. If you disable this policy or do not configure it, you cannot set this limit. Note: This setting does not appear in the user interface.

What it writes

Hive: HKEY_CURRENT_USER
Registry key: Software\Policies\Microsoft\Internet Explorer\Persistence

In Intune

No native CSP; import the ADMX (Intune-ready).

From Microsoft's Policy CSP DDF files (DDF v2 Files, February 2026), read 18 Oct 2026.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
