While upgrading to Exchange 2007 SP1 the server I use in my lab, I got the following error:

[ERROR] This role cannot be installed because the following roles are not current: MailboxRole
This role will not be configured because of the following exception: This role cannot be installed because the following roles are not current: MailboxRole

This machine has all the Exchange roles:

• CAS
• HUB
• Mailbox
• Unified Messaging

The error occurred just before upgrading the Unified Messaging role (the CAS and HUB went OK), so after some unsuccessful troubleshooting, I decided to uninstall the UM role from the command line:

setup /mode:uninstall /role:UM

I then rerun the SP1 setup (setup /mode:upgrade) and reinstalled the UM role. Everything is now working and fully upgraded. For additional notes regarding SP1 installation, read this post.

MSExchange.org recently published the last article of the series: Continuous Backup for Exchange Server with DPM 2007.
