Urgent: Exchange Server SP1 RU4 Removed from Download Centre


This has been steadily escalating this afternoon and the decision has finally been taken to remove RU4 from the download servers.  From what little I know one of the changes that was made to fix a bug in Exchange has highlighted a latent problem within Outlook.  Both the Exchange team and the Office team are looking into this issue.

What should you do?

  • If you haven’t yet installed RU4, do not begin a rollout and do not deploy RU4
  • If you have already installed RU4, contact Microsoft Customer Support obtain an interim update which fixes the issue.

RU5 is due for release in August and contains a change within Exchange that prevents this apparent data loss from occurring.

The full update is here..
