You have successfully migrated from an on-premise Exchange 2010 organization to Exchange Online.
All clients use Microsoft Office 365. You want to capture all edits made to user Michelle Smith’s
mailbox for 17 days. You want to have a rolling legal hold to preserve the data in the mailbox, with
the data not affected by any of Michelle Smith’s actions. What should you do?
A.
Run the following cmdlet:
Set-Mailbox -identity “Michelle Smith” -SingleItemRecoveryEnabled $true
B.
Contact the Office 365 help desk
C.
Upgrade to an Exchange Online (Plan 2) subscription and contact the Office 365 help desk
D.
Upgrade to an Exchange Archiving subscription and contact the Office 365 help desk
Explanation:
You should contact the Office 365 help desk to enable a Single Item Recovery (SIR) for 17 days. SIR is
enabled by default on all mailboxes in Exchange Online with a 14-day retention period. To extend or
decrease the SIR period, you must contact the Office 365 help desk.
You should not run Set-Mailbox -identity “Michelle Smith” -SingleItemRecoveryEnabled $true. This
action will enable SIR for an on-premise account. SIR is not enabled by default on an on-premise
account. In this scenario, you have upgrade Exchange 2010 to Exchange online so all accounts are in
the cloudbased service.
You do not need to upgrade to an Exchange Online (Plan 2) subscription and contact the Office 365
help desk.
A SIR can be placed on account with an Exchange Online (Plan 1) subscription if you want to have a
rolling legal hold of 30 days or less.
You do not need to upgrade to an Exchange Archiving subscription and contact the Office 365 help
desk. An
Exchange Archiving subscription provides a personal e-mail archive for users who have mailboxes on
Exchange Server 2010 and is not a requirement to have a SIR.
