I hope this is the right place for my question.
We are supporting a company that is about to merge with another one. Both of them are fairly small. They want to keep using their mails and the domains as usual. i.e. user@companyABC.com and user@companyXYZ.com.
I am not sure witch version of exchange they have already installed at their server, so I am going for the worst case scenario, that is for exchange 2003.
Can we use only one Exchange server to support both companies mails?
Depending on the answer to this, the other thing they have asked us is if some of the users, i.e. secretaries can have access to both companies contacts and calendars. Can this be done?
If you could point some sites with configuration information... I would appreciate it!!!
