Litigation

Azure Runbook – enable Exchange Online Litigation Hold

This script will connect to Exchange Online and enable litigation hold for all enabled users. Errors due to not having the appropriate license are ignored. Litigation hold can be enabled for users licensed with Business Premium, EOL Plan 2 or the Mailbox Archive add-on. Replace ‘svc-runbookcred’ with your runbook credential name. You can schedule to run nightly to pick up new users as they are added. If you like the script, made it cooler or need some help, please add a comment below! 🙂
