Modern Outlook mobile apps don't see Public Folder calendars. We bridge the gap.
Sharing calendars between different Exchange orgs often fails free/busy checks. We fix the feed.
Passthrough Encryption Active
Room and Equipment calendars are often hidden. We expose them for viewing.
Identify the target Public Folder or Resource Mailbox.
Publish the calendar to an HTML/ICS link via OWA.
Allow Lokr to proxy that link.
