Tag: Offline access

One of the settings for sensitivity labels governs how long items protected by a label remain accessible (including offline access) before reauthentication. The default is 30 days, which is a good balance between security and avoiding users having to constantly reauthenticate to open protected messages and files. If necessary, tenant administrators can change the validity period to be anything from 0 to 65535 days.

Now it can start without a network connection, which is something that Outlook classic has been doing for 27-odd years. The update provoked a search for where the new Outlook stores the data used when working offline, and we think we know where the data is.
