"Could not complete the operation. One or more parameter values are not valid".

Hello all fairly new to this page so would gladly apreciate some advice on trying to get past a niggly error message which is recuring despite carrying out Microsofts Solutions.
Any feedback will be a bonus as this fault is randomly popping up and is incredibly annoying doesnt seem to happen at specific times say when creating a task as microsoft document .
We are recieving a "Could not complete the operation. One or more parameter values are not valid".
For which i have tried a number of differing solutions via microsoft including creating new mail profile, renaming outlook data files, .ost and .pst repairer tool, outlook check and repair facilty as well as removing live meeting which can aparently cause a conflict. We are using Office 2003 SP1 and this is a networked PC gettin mail from Exchange 2003 server. An isolated incident here but still very annoying as other computers run fine using same hardware and OS ) Thanks Again Have fun all
