Hi,

I'm using this code with asp (no .net) to access a gmail Mailbox.

<%
Dim oSession
Set oSession = Server.CreateObject("OSPOP3_Plus.Session")
oSession.UseSSL  = True
oSession.OpenPOP3_5 "pop.gmail.com", 995, "myusername@gmail.com, "mypwd"

%>

but I get this error:

OSPOP3_Plus error '80004003'

Object reference not set to an instance of an object.

/Default.asp, line 5

Probably if the ID specified for the anonymous user in IIS doesn't match the ID of the user the com+ client was exported to impersonate, it will show that error.  By setting the id's the same, classic asp will have access rights to creating the com+ object

Error '80004003' is pretty generic, meaning it can be anything. Try the following steps:
1) make sure OSPOP3_Plus is properly installed
2) create a package under COM+ services, import OSPOP3_Plus.tlb there and set it to run under user with sufficient rights (no, it does not have to match IIS Anonymous user): create an instance of the object, connect to network/Internet, access to file system (if you are planning to save messages or attachments)
3) in case you have firewall or other packet-blocking software (anti-virus, anti-spyware, etc.) make sure OSPOP3_Plus is granted access to network/Internet and POP3 ports specifically (usually 110 and 995 for secure POP)

No problem. Glad it helped
