Classic ASP CDO.SYS has stopped working

Question

User-464213005 posted

Hi,

This is a bit of an odd query and might relate to IIS7, Classic ASP, CDO.SYS or even Outlook 2007.

I have IIS7 set-up on my Vista Ultimate PC for locally testing websites we build. I also use it to run a classic ASP application that stores our customer information. Part of that system allows us to send emails to our clients (not a mass mailer - just one at a time) using CDO.SYS. This has been working fine for a couple of years and I've moved it from PC to PC as I've gone a long without any problems.

Yesterday I upgraded my MS Office (on the same PC) from Office XP to MS Office Professional 2007 which includes Outlook 2007. Now when I try and email from our ASP application using CDO.SYS I get this error:

Microsoft VBScript runtime error '800a01ad'
ActiveX component can't create object: 'CDO.Message'
/crm/customer-newhistory.asp, line 105

(line 105 reads: Set ObjSendMail = CreateObject("CDO.Message")

I've tried Googling the error and various permatations but I don't know what to do to get it working again. I do have a copy of the application working on my Vista Business laptop (which doesn't have Outlook 2007 installed) so I guess I could copy and files needed from that machine if required.

I'd really appreciate any help anyone could give to try and resolve this.

Thanks in advance.

Hi,

Again, thanks for the quick reply.

I tried that and got this error:

The module "cdosys.dll" was loaded but the call to DllRegisterServer failed with error code 0x80020009

Any ideas what this means?

Thanks again.

Sorry, should have Googled that error before posting - I needed to run CMD as an administrator and now the dll has re-registered correctly.

I'll now test and see if CDO.SYS is working again.

0x80020009 - it means some exception occurred.

Can you try following:

Run regsvr32 /u cdosys.dll

Then regsvr32 /i cdosys.dll

 Hi Ganeshanekar,

If I used 

.To       = "[e-mail]"
.From     = "[e-mail]"
.Subject  = strSubject
.HtmlBody = StrMail
.Send

 

Working fine when I replace with 

.To       = strSendTo
.From     = "[e-mail]"
.Subject  = strSubject
.HtmlBody = StrMail
.Send

 

and it's not working.
