Hello- I've been asked to run a Discovery search on two different domains that have sent to us or that we have sent to. I would only be searching on the past 90 days because we purge our emails after 90 days.
I'm estimating on a typical work day we typically receive 20,000 emails and also can send out approximately 20,000 as well. This does not include our "internal" communications which I have no idea. Thus my questions - Have others found it safe to run Discovery searches during the working hours or should I do this after hours so I don't accidentally cause any system performance issues during the day for users? Or, is this not a problem due to how the searches are performed? When searching for emails to/from a particular outside domain, should I run the 3 months at once or run a month at a time to help not create any issues? If I want to then take the info from the Discovery Search mailbox and write it to .pst, is this possible? Or is it better to run a separate (perhaps, some type of powershell) to get this to a .pst? We lock down .pst on our users workstations via group policy so it makes it a bit difficult for me to do this via my workstation, so again, is there a better, say administrative command or way to do this? We are currently running Exchange 2010 RU2 SP3 Thank you very much for your help and feedback in advance. This electronic communication may contain confidential information.
