Outlook 2003 error when clicking on reply all or forward

When I click on either of these an error message appears stating: "The message interface has returned an unknown error, if the problem persists contact your systems administrator"

I have tried creating a new profile but I get an error "The action could not be completed the connection to the Microsoft Exchange server is unavailable. Outlook must be online or connected to complete this action"

Outlook is not set to offline, and emails are being sent and received successfully.

A little background: The user is running Windows 7. I believe (not 100% sure) an Outlook 2007 trial was installed, it expired an OEM copy of Office 2003 was installed and now this is happening, I think it may have been reinstalled but I am not 100%.

Any ideas on how to get rid of the error?

hi,
I believe that there is a confilict in the registry because you had outlook 2007 trial version and then you install office 2003. I suggest to uninstall from add remove programs all Microsoft office version and then restart your pc. After you restart the try installing Microsoft office again. Most propably the problem will be solved.

All versions of outlook share the same MAPI system and may be conflicting with the different versions.

Alternatively, the PST fileis corrupted.

if this is a networked system within a company, might be helpful if the same version of Office that is on the other systems, is also added to this one, rather than an OEM copy (you may have issues with updates/patches, as OEM support for 2003 has expired).

Make sure you have fully removed Office 2003 and any trial versions (might want to run CCleaner and give the registry a clean before re-install).  Then re-install 2003, and apply SP3 for 2003, plus any other outstanding separate patches/hotfixes from the Windows Update site, or local WSUS server if you have one.

Well this is still an issue.

Seems as though all Office installs are OEM software. I tried removing the OEM install and installing 2003 standard that I had on me but the install hangs on caching cab file or something to that effect.

I removed the users Outlook profiles and was completely unable to even access emails. Only way I got them back was through a system restore!

I think one issue is that HP tools is installed and will ask for a password before logging into Outlook. So Outlook is offline until this password is entered. I will removed HP tools and then create the new Outlook profile and see how that goes.

Does anyone have any other suggestions?

can't think of anything else off the top of my head, but make sure you applied all Service Packs and patches after you installed Office, before you launch anything.  On most HP systems i have worked on, the OEM Office Trial has been the limited version with no Outlook, and has no media, you are just required to buy a license key before the 60 trial ends.

how many users have this error??  if its just one or two, i would consider using the F11/Restore Disk option, to do a quick rebuild, after you back-up the users data.

There is a 60 day trial for Office 2007 but that expired and then an OEM Offcie 2003 was installed.
