Required Permissions for eDiscovery & Hold
Administrators or users who are members of the Discovery Management role group can perform searches of mailboxes in the Exchange Online organization for data that meets specific criteria and can also configure legal holds on mailboxes.
To Use in Place eDiscovery and/or place users on Hold you must add yourself or delegates to the Discovery Management Group from EAC Permissions section. This should be configured first. Log out then back in once added to this group.
NOTE: The change can take time to update. If you log back in and still don’t see the full set of icons in compliance management then log out and try later.

Personal Archive Storage Quotas – (call to MS Office Datacenter)
Each subscriber receives 50 GB of storage in the primary mailbox, plus unlimited storage in the archive mailbox. A default quota of 100 GB is set on the archive mailbox, which will generally accommodate reasonable use, including the import of one user’s historical email. In the unlikely event that a user reaches this quota, a call to Office 365 support is required. Administrators can’t increase or decrease this quota.

Recoverable Items Folder Storage Quotas – (call to MS Office Datacenter)
When a mailbox is on litigation hold none of the items in the Recoverable Items folder are permanently deleted. This makes it possible to reach or exceed the 30 GB quota for the Recoverable Items folder. Office 365 is currently “in development” of increasing this size from 30G to 100G. You can view this info and more on the Office 365 Roadmap.

InActive Mailboxes when a User is Deleted
By default when a user is deleted from Office 365 their corresponding mailbox (if present) is eradicated as well after a recovery period of 30 days.
Exchange Online makes it possible for you to preserve the contents of deleted mailboxes indefinitely. This feature is called inactive mailboxes. A mailbox becomes inactive when an In-Place Hold is placed on the mailbox before the corresponding Office 365 user account is deleted. The contents of an inactive mailbox are preserved indefinitely. This allows administrators, compliance officers, or records managers to use the In-Place eDiscovery feature in Exchange Online to access and search the contents of an inactive mailbox. Inactive mailboxes can’t receive email and aren’t displayed in your organization’s shared address book or other lists.
If a hold isn’t placed on a mailbox before it’s deleted, the contents of the mailbox won’t be preserved or discoverable. The mailbox can be recovered within 30 days of deletion, but the mailbox and its contents will be permanently deleted after 30 days if it isn’t recovered.
