Remove OneDrive From Shared Mailboxes
Use this PowerShell script after an offboarding review has confirmed that OneDrive sites owned by shared mailboxes are no longer required. Start with -WhatIf, verify every mailbox-to-site match, and use -Purge only after the retention and recovery decision is final.
Portal Redirect
Portal Redirect is no longer needed for new deployments. Opening a SharePoint URL directly already starts the appropriate Microsoft sign-in process when required and returns the user to SharePoint.
SharePoint Farm Wake-Up PowerShell
Use SPWakeUp only as a reviewed legacy script for an existing SharePoint Server farm where administrators deliberately want to request every discovered site after an application-pool recycle, server restart, or maintenance window. Do not use it for SharePoint Online.
SharePoint Configuration Cache Cleaner
Use SPCacheCleaner only when a diagnosed SharePoint Server configuration-cache problem requires the documented cache rebuild procedure across a farm. Review every target server and take a configuration backup first. Do not use it as routine maintenance or for SharePoint Online.
