Outlook recreating OST / mailbox each logon, after upgrade from hosted ex2003 to ex2010
Posted on 2013-01-08
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
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
