SYMPTOMS
The migration wizard is not extracting more than 16,000 items per folder when migrating from Notes to a .pst file.

The size of the mailbox she is trying to migrate is ~ 1.6GB


 * The No of item is ~4k when migrated we getting only 1.5k
 * It appears that smaller mailboxes are migrated fine, we checked one which had only ~350MB. She was still missing some messages it appears that the total No of items was more that 16128, so we were missing everything above that No.



RESOLUTION
This is a limitation when migrating from a Lotus Notes database. The folder containing more than 16000 items will need to be reduced in volume. Notes API can only get 16,128 items from any given folder.

1 gb size limit to migrate - seems to work if we split up the migration in date ranges

16 000 limit of messages in one folder - Works if we split up the migration

Here are a few possibilities:


 * 1) Migrate by date range
 * 2) Reduce the size of the Mailbox on Lotus Notes server
 * 3) Use Outlook to dump all the mail to PST and Exmerge IN to the user's mailbox.
