Cause
IMPORTANT: The OST file can only ever be retained (re-connected to the new target mailbox)if the mailbox was processed in a Remote User Collection (RUC). If this condition was not met then OST file will be recreated and new one downloaded from Exchange server regardless of settings in the CPUU batch file, while old OST file will still be backed up and WILL NOT BE LOST.If this was not desired outcome please roll back CPUU profile updating, process the mailbox in Remote User Collection andthen run CPUU again.

Always(Recommended) - EMWprof will update all the OST profiles. Old OST files will be removed and new OST files will be created.
II.Settings for updating profiles of the mailboxes migrated within the Remote Users collections:
Never- CPUU will not update any OST profiles. These profiles will be skipped.
When Possible to keep OST(Recommended) - CPUU will update only OST profiles which target mailboxes were processed as part of Remote User Collection and successfully recreated by the Mail Source Agent. This option is provided to preventrecreating of the OST files for the target mailboxes that the Mail Source Agent failed to recreate for some reason.
Always- CPUU will update all the OST profiles not depending on whether the target mailboxes were processed in Remote User Collection and successfully recreated or not. When selecting this option one should be aware of the risk of recreating the OST files and losing some data from the old OST files.
