Comparing Search-Mailbox and Compliance Search Actions

Comparing Search-Mailbox and Compliance Search Actions

Table 1 summarizes the functionality available in Search-Mailbox and purges executed with compliance search actions. Both have their unique characteristics: compliance searches are faster and can process more mailboxes in a single operation but are limited to what they can remove from a mailbox. Search-Mailbox can focus on Recoverable Items or ignore a mailbox’s archive, while compliance searches can focus on a single target folder. The biggest difference is that Search-Mailbox can copy items to a target mailbox when it removes them from other mailboxes. You can export items with a compliance search, but you must do this separately and before you remove anything.
