This worked fine for me.
Hope this helps.
Please Rate if this helps u.

Hello;

Thanks for the responce'
I have actually used that piece of code as well and it does work
only if you have your outlook up and running....
I managed to find another piece of code that does not requires
outlook to be up .....check http://www.codeproject.com/useritems/mailcheck.asp
Now Here is another question that I am throwing at you and hope you 'd be able
to answer it.


When I use OutLook Express and set my pos3 server values It does work but with
Exchange it does not seem to work although the code is using MAPI

Is your mail server by any chance a Pop3 server or is it not?

And if it is not ,did you do any change in settings in MS/Outlook to
get your emails through this Code?



Thanks

Share what you know and ask what you dont....

The code I posted works even if the Outlook express is not up.It asks for the user id and password for the user profile.
I didnt change any settings for this.

As you can see below , I m using exactly what you are doing.
I have a toolkit that pumps emails to my account for testing.
my app cant pick up the emails and it keeps tellig me that "On ReadMail MAPI_E_NO_MESSAGES"
however when I bringup my Outlook Express , it manages to ftech the sent emails and then my app pickes them up...
I can understand that this is perhaps something that you probably no nothing about...

Thanks

You reading the msgs two times.That is why u r getting that msg as no unread msgs.


/******************************************/
/***This block is used to find the unread msgs.AFter executing this block , the msgs will become read.But again u r reading the msgs using shared session, by that time,msgs were already read.That is the mistake u r doing.***/

Pl rate if this helps u

Thanks-That is a bug I missed , but that did not change the story.still it comes up with
2002-3-26 11:19:9 On ReadMail MAPI_E_NO_MESSAGES
2002-3-26 11:24:18 lpfnMAPILogon was SUCCESS_SUCCESS
2002-3-26 11:24:18 On ReadMail MAPI_E_NO_MESSAGES

The **** thing works when Outlook express is up..

Thansk and cheers
