Integration with ArcSight would be very helpful. The user mailbox management is poor. For example, if I want to restore a complete mailbox then it doesn't keep the structure of the inbox intact. When the emails are restored, they are in a single folder that we have to extract and restructure. At times, the restoration doesn't work properly. It would be difficult to opt-out of the services because it would require the transfer of a lot of data from the cloud to on-premises storage. Technical support should be more available to the Indian market.
