You have deployed mail quotas in your environment and your Notes Clients are configured to use local replicas or managed replicas.
Still you experience mail files are growing over quota limits without user complaints. How is this possible?

It seems there is a bug in the IBM Domino mail template version 9.0.1 which allows to create and send new mails even when the mail file is over quota.

Reproducing the problem
When working on the server replica:

• create a new mail and try to save it will correctly display this warning:
  

When working on the local replica:

• Create a new mail will display this error message, but clicking OK allows to continue saving & sending the new mail.
  
  Notes.ini variables have been verified to be set correctly on the client
  Check_Quota_On_Mail_Create=1
  REPL_OBEYS_QUOTAS=1

The problem is known to IBM and is documented as LO83693 "Enforcing Quotas on new mail creation in local based mail files not reliably working in Notes 9.0.1"

How to fix it
As usual there are two options:
a) Wait for IBM to provide a new version of the mail template - maybe this will be done in the next major release.
or
b) fix it yourself by modifying the template with your Domino Designer client as described below:

Within the QueryOpen event of the form(s)  "Memo", "Reply" and "Reply with History" , "To Do", "_Calendar Entry", etc. search for the quota checking code and remove the "Executive" statement incl. its brackets.


Interesting to note that special forms do not contain this code so they do not need to be patched

Please note that design elements need to be signed properly in order to avoid ECL warnings on the client side.
