First of all, if you are trying to provide access to those emails while your Exchange solution is down, you have to replicate the exchange system. Read mail and all. Most users won't be too happy about any messages marked read coming back as unread when exchange spools it all up.
While it might be possible to get a webmail interface up, I'm sure most of your users probably won't like the experience much. I'll suggest that unless there is specific Exchange services you NEED, Zimbra would probably handle what you want. Plus Zimbra offers support for effectively clustering the system. So you should be able to do staged upgrades without downtime. Just a good point here. If you are mission critical on your email, you really should look at some way of having a spare that you can do your maintenance on and do effectively a quick failover to the upgraded machine and then upgrade the former primary. If you aren't really that mission critical, you can easily take the time to be down and do whatever upgrades. I guess my suggestion is more along the lines of, you should consider what are your risks of being down, and what is your risk of losing everything. Then what are your fall backs. Then what is the difference between your fall back points and the cost of a new email server to do the upgrade and switch over to. ----- Original Message ----- > My office uses Exchange 2007 for our mail, which we host locally.
