Good day
Hope you can assist.
I have a Outlook 2010 on Win7 64bit on a HP Probook 450.
The notebook is on a domain and the user gets his mails of exchange.
When my user receives new mail from only 2 out of 30 odd users, he cannot open them.
He gets a error message, Outlook cannot find item.


But if I go to autodiscover.xxxxxx/owa I can open the mail and reply to it.
This occurs in cached and non cached mode.
This happens in normal Outlook and in safemode Outlook.
I have also uninstalled and reinstalled MS Offcie 2010 which did not help.
Please advise, I'm going nuts...
Thank you
Gideon
