Last week I had the request to obtain the quota on the mail file when creating local replicas. After some search, I found this NOTES.INI entry:
Check_Quota_on_Mail_Create=
http://www-01.ibm.com/support/docview.wss?uid=swg21247798
This setting is not only used when creating local replicas, but also to check the quota when creating new mails !!
