问题
We are upgrading our server to Windows 2012 from 2003. Our application use CDO 1.21 and MAPI to send mails, I know I have to use SMTP/ OOM/AWS. At this late stage I don't want to do make changes in our programs right now - there are 80+ :)
When I am going to MS site to download CDO 1.21, Windows 2102/Exchange Server 2010 SP3 is not specified under supported platforms.
I am able to download CDO 1.21 for Win 2012. But now when I am connecting via MAPI, System is throwing error:
The information store could not be opened. [MAPI 1.0 - [MAPI_E_LOGON_FAILED(80040111)]]
MAPI Code :
Set objMAPI = New MAPI.Session
objMAPI.Logon ShowDialog:=False, NewSession:=False, ProfileInfo:=gobjINI.gstrExchangeServer & vbLf & gobjINI.gstrProfile
'Add a new mesage to the OUtbo Messages Collection
Set objMSG = objMAPI.Outbox.Messages.Add
Error is thrown on third line: Set objMSG = objMAPI.Outbox.Messages.Add.
