Outlook 2010 on Exchange 2013

Hi experts,

We are migrating from Exchange 2010 to 2013. WE have a mix of  Win7/Office 2010 and Win10/Office 2013 in our environment. After the initial setup, when we move a user who is using Win10/Office2013 from Exchange 2010 to 2013, it works fine. All URLs are pointed towards the load balancer (KEMP) and the user feels no difference. But if the same user is using Win7/Outlook 2010, it does nothing and  Outlook stays in disconnected mode. If we try and recreate Outlook profile, Outlook does not open and instead it gives the error, "cannot open your default email folders. you must connect to microsoft exchange with the current profile before you can synchronize your folders with your outlook data file"

Office 2010 is running on the latest version of SP2, all updates are installed. We even moved the PC outside WSUS to get any additional updates. Any help will be appreciated.

Thank you

Make sure to update to Office 2010, SP3 on the affected computers.
and Make sure the autodiscover record is present on those computers (using ping autodiscover.domain.com)

Hi Jose,

I have verified all that. If I install the same office version on a Win 10 machine then it starts working. It is not working on Win 7 for some reason.

if I installed office 2013 on Win 7, it does not work. Not sure what to look for.
