Good morning

We are experiencing the above problem on all Outlook clients after a Rackspace hosted exchange service migration.

None of our mobile IOS or Android Cklients have this prblem.

Cached Exchange mode is on

We do not use roaming profiles

Outlook data filers are at C:\Documents and Settings\*Userbname*\Local Settings\Application Data\Microsoft\Outlook

Clients are a mix of XP Pro SP3 and Win 7 Pro, with Office 2010 Pro Plus, Outlook 14.0.61289.5000 (32-bit)

Our LAN Server/DC is Windows Server 2003

On inspecting this location we see a number of OST files, named
emailaddress - emailaddress.ost
emailaddress - emailaddress(2).ost
etc.

Of fairly equal size, one created each time a user logons on to Windows and starts Outlook, but all with last updated dates of the current day

We added CName Autodiscover records to help automate client setup, but have also manually set some up with the same problem
