I came in this morning to a dead exchange 2010 server with no backup. We're a relatively small shop with not a lot of users. Here's my plan and I'd like some input from the experts. We were in the planning stages of upgrading to Exchange 2013. I would like to export everyone's outlook to a pst. Already tested this with one user and we were able to export to a pst everything since Friday. Next I'd like to install a new server with Exchange 2013. After that is up and going then import each user's pst file. What are some thoughts about this?
