I have a physical Exchange 2003 box XEON 3.00 GHZ with 4G of memory.
C: OS Drive = 27GB. with 2.65G free
E: = DATA Drive 245G with 10G free
F: Log Files Drive 68.2G with 66.7GB Free
I just started with this company approx 2 months ago. As their Exchange Admin, here are my findings of our Exchange Server. As you can see i am running out of disk space for my data drive E:. Due to company policy i cannot delete (YET) terminated employees mailboxes and i have approx 20GB's worth of terminated employees mailbox. Also I only have 1 mailbox Store.
I also have 4 clustered VMWare ESX 4.1 VSphere servers. With enough resource to virtualize exchange. But with Exchange 2010, i am trying to decide the best approach to upgrading and fixing my current state. So my questions have multiple parts.
1. Can Exchange 2003 and Exchange 2010 Co-Exist using the same domain?
2. Can Exchang 2003 and Exchange 2007 Co-Exist in the same domain?
3. If the answer to Question 1 is Yes, dont answer Question #2
4. If the answer to Question #1 is NO but answer to Question #2 is yes, if i buy Exchange 2010, i do have rights to install 2007 yes? then upgrade 2003 to 2007, then do it again from 2007 to 2010?
I can virturalize Exchange and give it more disk space. Since i only have 1 mailbox store, i can create another mailbox store for my terminated employees, but i need drive space.
1. is it OK to map to a shared drive from another server and create a mailbox store there and put all my terminated employees to that store? since most likely, these mailboxes will not be viewed. Only when needed and probably only 1 mailbox at a time?
2. If that is not adviceable, or will it be better if i connect a USB drive on the exchange server itself, can i create the terminated employee store there?
3. Or can i put the terminated employee store to the F: drive and put its log files on the E: drive the reverse of the primary store?
