Well availability of Outlook 2010 was a much anticipated due to the very famous Personal Archive feature in Exchange 2010. Butâ€¦people were in for a surprise when they upgraded to Outlook 2010 RTM from MDSN or TechNet – the Personal Archive and Retention Policies went missing.
The issue was discussed at length and as per one of the Outlook PM – Technet and MSDN have Pro Plus Retail with keys that do not enable the Outlook Pro features. So what this means is that Retention policies and Personal archive are not available as of now in Outlook 2010 Pro plus retail version on TechNet/MSDN, using the keys there. The Volume Licensing Keys on the other hand do not have this issue.
I see and can see a lot of discussion on this decision from Microsoft! Lets wait and watch !
