Exchange Server - High Availability
Posted on 2011-02-15
My goal is to have uninterupted email capability in the event of server hardware failure. I currently have two Exchange 2003 Enteprise servers. The second server currently is only an information store. I have two main questions.
- is it reasonable to assume that if my 1st Exchange server would crash, I could redirect incoming and outgoing email to the 2nd server, assuming I make DNS changes as necessary? Or am I missing something vital?
- If someone's mailbox was located on an information store that resided on the server that is down, can a temporary mailbox be created on the 2nd server Information Store? I've tried this in the past and even though the Information Store is down, it says that user already exists. This makes sense, but is there any way around this? For instance, if my CEO's mailbox was on an information store that crashed, how can I get SMTP email to/from him until that store is brought back online?
