Blackberry Bes no mail deletion on device after upgrade to version 9

i´ve upgraded to vers. 9 from 8.5.2 on windows 2003 server. also on my blackberry bes server.
since than, when user delete a email on the notes client, the mail is not deleted on the device. also read/unread marks are not reconciled. even when they do “reconcile now”.
when a email is deletet on the device, it is quickly deletet on the notes client.
caldendar is working fine.

on the domino server, mail and bookmark template and files are on vers 8.5.2.
on the bes the templates are from vers. 9.

bevore the upgrade everthing worked fine, but i´m not able to find the cause.
all settings are correct.

any idea?

that brings me not further.

vers. 9 is could also be labeled 8.5.4.
on 8.5.3 there was no problem…
due to the fact that all is runing smoothly except the problem described, I guess there is a setting, a template or a file what´sa causing the problem.

a clue to that would be more helpful…

BTW: The cause may be you’re running a completely unsupported and probably untested configuration.
