MS Office Forum / Outlook / Programming VBA / April 2008MAPI Session Logon error
Hi All, I have a Visual Basic application which has the below code Set Session = New MAPI.Session ProfileInfo = ExchangeServer & vbLf & UserId Call Session.Logon(, , False, , , , sProfileInfo) Set Contacts = Session.GetDefaultFolder(CdoDefaultFolderContacts) It is working fine in my PC with WINDOWS XP Professional and OUTLOOK 2003. But the "Set oContacts = ..", given in the above coding snapshot returns an error message, in one of the user's PC. The error is happening in a system with WINDOWS 2003 and OUTLOOK 2007. When I replace the statement "Call oSession.Logon(, , False, , , , sProfileInfo)" with the statement as Call oSession.Logon(, , True, False), it is working fine Can anyone tell me, why this is happening, is it some envvironment issue? I cant change the code in the application, since this is the only user, who is having the problem and the others (I hope all are using WINDOWS XP, with OUTLOOK 2003) are not having the problem. Did you actually install CDO 1.21 on the Outlook 2007 system? It is a separate download.

Yupe, I have got CDO 1.21 installed. But still it is not working. > Did you actually install CDO 1.21 on the Outlook 2007 system?

So the Session instantiates when using ShowDialog? Does the user enter their normal logon in that dialog? Do the parameters for the dynamic logon look valid on the problem machine? How are you deriving ExchangeServer and UserId? In general, when using a dynamic logon (where UserId must match the existing mailbox name) you'd use something like this: Session.Logon "", "", False, True, 0, False, sProfileInfo SignatureKen Slovak [MVP - Outlook] http://www.slovaktech.com Author: Professional Programming Outlook 2007 Reminder Manager, Extended Reminders, Attachment Options http://www.slovaktech.com/products.htm > Hi All, > [quoted text clipped - 22 lines] > with > OUTLOOK 2003) are not having the problem. For the first question, No, the user specifies the admin details of the exchange server The server details are from the database and the same details are used by other users, where the program is working fine. > So the Session instantiates when using ShowDialog?

Does that user have the same permissions as other users? Are you sure that the user is using the correct alias and that they have permissions for that alias? Did you try the suggestion I made about changing the logon arguments? With a CDO logon it's a matter of permissions and getting your parameters correct.

I dont think, there is anything related to the permission of the user. Because, if i set the code, in such a way that the profile name is selectable, then the code works fine, or else it doesnt. This happens only in this system. All other system, the profile name is not selectable, but the code works fine.... > Does that user have the same permissions as other users?

Hi AVIS, > Set Session = New MAPI.Session > ProfileInfo = ExchangeServer & vbLf & UserId If you have two userIds where one is the prefix of another you cannot log on to the short userID with a dynamic profile, because the two userIDs are counted as valid and none is chosen automatically. So if you have something like "user" and "userA" you will not be able to log on with user with a dynamic profile. This got more complex with Exchange >= 2000 because several AD properties of a user are looked up. So the mailbox alias is only one attribute to look at. We had problems with the windows logon name as well. So please verify if the problematic system is really the system or if you just use a userID which is a prefix of another mailbox alias or user name. -- SvenC Actually, it should be possible to do that by prefixing the userID with "=" to force an exact match, e.g. "=" & UserId SignatureSue Mosher, Outlook MVP Author of Microsoft Outlook 2007 Programming: Jumpstart for Power Users and Administrators http://www.outlookcode.com/article.aspx?id=54 > Hi AVIS, > [quoted text clipped - 22 lines] > -- > SvenC Hi Sue, > Actually, it should be possible to do that by prefixing the userID > with "=" to force an exact match, e.g. "=" & UserId I tested that a while ago and had problems with it. It could be different behaviour for Exchange Server MAPI and Outlook MAPI. IIRC it did not work for Exchange MAPI and ExchangeMAPICDO -- SvenC Hi, I tried implementing ur suggestions, but still it is not working. I also found that the profile name that I have selected is not prefixed to any of the other user ids. > Hi Sue, > [quoted text clipped - 7 lines] > -- > SvenC Profile names and user IDs are two completely different things.

As far as the resolution of the user ID, it happens correctly and gets resolved as expected. Proper permissions have also been given to user id. > If you type that UserID into the To box of a message, does it resolve to an Exchange user? > [quoted text clipped - 23 lines] > >> >> -- > >> >> SvenC Any Updates? > As I informed, the appointments are getting created, if the below statement > is used for the logon [quoted text clipped - 36 lines] > > >> >> -- > > >> >> SvenC An alternative would be to provide the name of a profile.
