I have a Visual Basic 6 application where I use 'GetFreeBusyState' function.
My problem is the following:

I have two users with a similar username and when the program use the code:

ObjRecipColl.Add ObjBuzon.Nombre
ObjRecipColl.Resolve                                <--------------- Line
where appears the error
Set ObjOneRecip = ObjRecipColl(1)
FreeBusy = ObjOneRecip.GetFreeBusy(StartTime, EndTime, Interval)

the application return 'MAPI_E_AMBIGOUS_RECIP

I'd be very grateful if you could help me to solve the problem:)
