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.
