Just wanted to highlight an issue we've seen at my organisation where an MSP file is does not fully install the Outlook 2013 branch where it is modifying an existing installation where that branch is not installed.
The scenario is that Office 2013 SP1 has already been installed using an msp file which does not install access, outlook and lync branches. It also hides and locks these features.
We're then following this base install at a later date and enabling Outlook using another msp file. Despite the msp file installing all features for the branch, Outlook 2013 *does* then appear, but mapiph.dll (and potentially other files) are missing from the installation.
One symptom of the missing mapiph.dll file is that local searching within outlook does not work, such as from the exchange offline cache.
Our workaround has been to enable these branches using config.xml instead. For example...
<Configuration Product="ProPlus"><Display Level="none" CompletionNotice="no" SuppressModal="yes" AcceptEula="yes" /><OptionState Id="OUTLOOKFiles" State="local" Children="force" /><Setting Id="SETUP_REBOOT" Value="Never" /></Configuration>
As an aside, the msp files both had different names. I'm aware this is required.
Just thought I'd put this out there!
