Quick Tip: Fix “Enable Web-based distribution” greyed out in offline address book
After upgrading from Microsoft Exchange 2003 to Exchange 2007 or 2010 you might notice that the "Enable Web-based distribution" option is greyed out. The first thing to check is if you have moved the Offline Address Book generation to an Exchange 2007/2010 server.
However if you have already done this and the option is still disabled it can easily fixed by running ApplyMandatoryProperties on it. This can be done by running the below powershell command
Get-OfflineAddressBook | Set-OfflineAddressBook -ApplyMandatoryProperties
Et voila! you can now "Enable Web-based distribution"
Cannot install the Certificate Authority Web Enrollment component
I have recently been faced with a Certificate Authority server running on Microsoft Windows 2008 R2 that was refusing to have the Web Enrollment component installed.
I have tried installing by the GUI and using powershell using add-windowsfeature ADCS-Web-Enrollment and both method failed with the following error
"Certification Authority Web Enrollment cannot be installed on this computer or Error: Cannot install Certification Authority Web Enrollment."
The solution to this problem is
- Run regedit on the server
- Browse to HKLocalMachine\System\CurrentControlSet\Services\CertSvc\Configuration
- Change the SetupStatus key to 0×6001 (it was 0x6003 in my case)
Et voila you should be able to install the web enrollment now without issues

Outlook Web Access did not initialize error on Exchange 2007 SP1 after installation of Rollup 5
Installing the rollup update 5 on a machine running Microsoft Exchange 2007 SP1 might cause your Outlook Web Access, OWA, to fail with error Outlook Web Access did not initialize
I have already experienced this error at 2 of my customers on fresh installations and I am surprised I didn't find this error documented at Microsoft (Maybe I didn't look hard enough)
The problem is that, for some weird reason, the installation of the rollup update 5 is removing the Exchange server from the Exchange Domain Servers group !
So if you are facing this issue simply find that group, add your exchange server account to it and restart your server. That should do it!
