In-place Hold (eDiscovery)

I’ll explain In-place Hold feature on eDiscovery, this commented by Office 365 for IT Pros which I bought.

In-place Hold : This defines how Exchange Online will hold content located by the search criteria. If set, you can hold data indefinitely or for a defined number of days based on the date the item was received or created in the mailbox.

All eDiscovery searches automatically examine deleted items held in the Recoverable Items structure, including those retained to meet in-place or legal holds imposed by this search or other searches. If an item is found in Recoverable items, it can be retrieved when the search is subsequently used to copy items to the discovery mailbox.

When I see that explanation , I see eDiscovery is not a unique place to store all messages, etc , this feature is related user’s hidden Recoverable Items structure, and you must know if Recoverable Items structure exceeds 100gb , deleted items shouldn’t work , so as to use effectively user mailbox under office365 environment, it’s better idea to set online archive to all user mailboxes

Electronic Discovery(EDiscovery)

Sometimes defined as how records managers and litigators discover content stored in electonic format. It means the process by which searches are conducted across online sources so that information meeting the criteria for a legal discovery order can be found and made available for review

Both Exchange Online and SharePoint Online suppor in-place holds. It works by retaining content where is stored when a discovery search is performed. In-place hold is able to include all kinds of content stored in a mailbox or site. If items that come under the scope of an in-place hold are edited or deleted after hold is created, the application ensures the information is retained. For example, if a mailbox owner attempts to delete an item that is on hold, Exchange Online creates a copy of the items in a folder in the Recoverable items structure. The copied items are invisible to users and client but can still be discovered and retrieved by searches. [All coments are gotten by office 365 for IT pros book]


As I know the Recoverable items structure quota is 100G, if that structure is exceeeded to that quota, there are some odd symptoms such as deleted items folder cannot clean-up even if users are trying to deleted items from user’s folder, so as to use EDiscovery feature for storing and searching data , I think users need to use online archive instead of deleteing items on their folders.


Anyone who are reading this EDiscovery feature, you need to know that Recoverable items sturcture, if you see Office 365 for IT Pros mentioned when that structure’s quota is exceeded , it needs to contact to increase or not of that structure, but when I checked to ms engineer, that feature is not use.
