Hello,
We migrate our existing Exchange 2003 Infrastruktur to Exchange 2010 SP1 RU3. Everything seems to work fine but on the Outlook 2003 Clients we can send and receive emails. But when we press Send / Recieve the folloing error occurs:
Task Microsoft Exchnage Server reported eror (0x80040115): The conection to the Microsoft Exchange Server is unavailable. Outlook must be online or conected to complete this action."
I tried new profiles / Cache Mode / Online Mode / SP3
i suspect OAB but there are no synchronisation Problems and a deploy it on everey way...
Have anyone an idea to get rid of this problem?
Thanks for your help
