Migration Archive Hybrid

Rods used Ask the Experts™
Good afternoon everyone!

I am performing mailbox migrations in a Hybrid environment!

Why am I having a problem in 3 boxes where I do not change 2013 are they? Archive while performing sync is giving the following error.

This Mailbox has 16GB, but this is being used as a mailbox or several users as members.

Migrated data:
Migration rate:
Error: MigrationPermanentException: The file size 104.8 GB (112,571,089,611 bytes) exceeds the destination quota of 100 GB (107,374,182,400 bytes). The file size 104.8 GB (112,571,089,611 bytes) exceeds the target quota 100 GB (107,374,182,400 bytes).

The error states the issue.   You obviously have 100gb capacity on the mailboxes.   The date you are trying to migrate is 104gb.  You may need to  do some cleanup before migrating.  Do they need anything in the deleted items folder?  If not, remove it.    Maybe archive some extremely old mail out to a local .pst file  then migrate.
