Silent upgrade of client from v9.0.4 to v10.2 causes ribbon to disappear
We're in the process of upgrading our back end servers from v8 to v10 and are at the stage were we have our 9.0.4 servers on Windows 2008 R2. Before we do the final upgrade to v10.0.2 we are going to use SCCM to upgrade our client estate (Windows XP SP3 with Office 2007 and WIndows 7 with Office 2010) from a mixture of v8 and v9 clients to the latest v10.0.2 client.To facilitate the roll out we'll be using a silent installation using SCCM like we have with our older clients in the past.
I have packaged the msi with the requisite command line to suppress reboots and the install goes fine (Appears in programs and features, can retireve mail, entry is in the Add-Ins section etc.) but the ribbon in Outlook 2010 does not show (Tried four different computers so far). If I do a manual upgrade using the setup.exe then the install works fine and the ribbon is shown. On a Windows XP/Office 2007 machine the silent installation works fine as well although all of these have been on a limited number of trial machines.
On the problem machines after the upgrade has broken the EV client I've tried a repair, removal and re-installation, client reset, re-synching ev with the users mailbox and nothing helps. Below are two log files from two different clients with the issue. RPC over HTTP is allowed in the policies and were fully working with the 9.0.4 client.
The only way I can get these PC's to work which used the silent upgrade option is to delete the mail profile and re-create it but this is totally impractical for over 1000 machines.
Any ideas or help will be much appreciated
