Litigation Hold Can Max Out Recoverable Items 30 GB Limit

In MS Exchange, if you place a litigation hold on mailboxes to preserve email messages for a long period of time, keep in mind that modified or deleted Outlook items will be preserved in the Recoverable Items folder. This may cause the data stored in this folder to exceed its default maximum size of 30 GB.

Have the Exchange admin monitor the folder size, or sufficiently increase the default to deal with the accumulated data.
