Data retention/ eDiscovery/Compliance basics
Data is always indexed/searchable, what Retention in the SCC and holds in general allow you to do is prevent users from deleting data and make sure it's retained for legal purposes.
As for 2), holds can vary in type - some of them can apply to specific content only, some to specific location, some might be for a specific duration. You can have multiple holds applied to the same user/content, depending on the case. If you put the user on a permanent hold, you dont necessarily need to use the Hold options when creating a new eDiscovery case. But that's more of a matter of following the policies in your organization.
Thanks for your response Vasil.
Yes, we can create multiple types of holds in the case however I believe, a hold specific to a case will hold the data present in a users mailbox at that point of time and mails deleted thereafter.
For a legal matter specific case in eDiscovery which ivestigates historical emails, the holds inside a case won't come handy (except the emails present currently in user's mailbox). In these scenarios, the holds set up initially based on organizations mail retention policy will come to the rescue.
Also, if I choose to setup mailbox in-place hold for all the employees in my company, is the storage space alloted to a user in Office 365 plan used for this or is it a separate chargeable storage (https://technet.microsoft.com/en-in/library/exchange-online-limits.aspx). How does the storage cost work in retention scenarios ?
As I said, how you decide to use holds in your organization is up to you. The functionality is there.
You dont need to worry about additional storage. Each mailbox has dedicated quota for the RecoverableItems subtree, where (deleted) data on hold ends up. You get 100GB for mailboxes put on hold, and it can now be further increased.
