In-Place Hold [E2013] [EWS]

Hi,

Can you please clarify me whether the following scenarios are possible by the help of EWS for Exchange online 2013.

1. Enable time based in-place hold.

2. Use Search-Mailbox operation based on the Hold-Id. 

3. Specify the message types and Start-Date and End-Date in the Search-Mailbox or SetHoldOnMailbox. 

If possible can you please provide me the SOAP XML requests?

Thanks,                                                                                                                                                             Nandita
