we have an exchange 2007 server (sp1) that has been in place for nearly 3 years. all of a sudden, newly created users cannot connect to their newly created mailboxes using outlook. like i say, this server has been sitting there for quite a while, no changes in environment and nothing (obviously) different with our networking environment. ~300 users.
things a new user CAN do:
1. CAN use OWA to access mailbox
2. I can add that new user's mailbox to MY Outlook client and expnd his inbox.
This now happens with each new user. Existing ones, so far, have been unaffected.
any help? or even a small nudge in a direction?
sincere thanks to anyone that can help shed light.
