I have the following code running to create a mail merge file. The
Users sheet contains all the contact information. The FreeAccess sheet
contains the users' IDs and the contents for the mail merge fields.
There could be as many as 30 rows per user on this sheet. The code
searches for all the rows for each user on the Users sheet and copies
the contents of each row of the FreeAccess sheets for that user to the
user's single row on the Users sheet. The problem I'm running into is
that I can run 250 records in about 15 minutes. It will run 500
records in an hour and 1000 records in 4 hours. At this point it's
quicker for me to run these in batches of 250. Is there something I
can do to stop this exponential increase in processing time so that I
can run larger batches more efficiently?

A quick solution may be to put

Application.screenupdating = false

at the start of the process, and

Application.screenupdating = true

at the very end.

Thanks, Keith. I have that in there already - just posted the
relevant code. The rest of it is doing to formatting for column
headings, etc. The code I posted is where all the real work is being
done.

Ok, option 2 is to re-code to get rid of the unnecessary .select
and .activate methods. To get info from the worksheets and ranges you
don't need to select/activate them, always slows things down.

e.g.

replace

Worksheets("Users").Activate
lngKOU = Cells(lngUserRow, 1).Value

with

Worksheets("Users").Cells(lngUserRow, 1).Value
