Hi All, I got a new assignment for Setting up the Infrastructure for 5000 Users approx. Now the scenario is The ORG already using POP3 to access the email in Microsoft Outlook 2007 and Mobile. Now here the question is assessment of the Existing Email Usage and hosting Vendor is no more supporting us. I am not sure if i can achieve it by using the PST Capture and can have atleast Total PST Usage within the ORG and Size of the Standard Folderwise. Please suggest what could be best approach for getting the storage Size, Avg Send/Receive. Thanks in Advance, Know more about Messaging :-)
