Without providing "specifics" - you're asking those reading this and in a
position to provide a potential answer "to surmise" what the error is and
what's causing it. Without details - any answer is nothing more then pure
quesswork on anyone's part and more often then not is a complete waste of
time for all concerned.
Having said that - if you're consistently getting the same error "all the
time" importing the same file into the same folder without deleting the
records you originally imported - then without knowing the exact msg -
doubtful anyone could help you unless they provided a "lucky" answer. It
would however indicate a problem with your input data (if you didn't exceed
the capacity of your contact folder). The first place I'd look would be at
records in and around 3000 or 30,000 (IF the number refers to the record
number in the first place and not something else). IF it does - then you
most likely have a problem with your input data file and suggest you look at
the records surrounding #3000 (or #30000).
Other then that, it's possible that the number of contact records exceeds
the capacity for the setting of the PST file. Ergo - how many contacts did
you have to start with? How many are you trying to import? .........so on
and so forth (but if you haven't been deleting the contacts you've imported
each time then it is <EXTREMELY> unlikely that this number has anything to
with this since it should be consistent from run to run).
