Problem with new mail notification - Notes.ini NewMailSeqNum<RepId> for each mail database

I have configured different location for each notes client user. There is different mail database in location configuration document (and different user id - other parameters are the same).

I have problem with new mail notification - notes client generates NewMailSeqNum in Notes.ini only for one user (admin) and for all other users (locations) it uses NewMailSeqNum without determining replica-id. This makes mail notification completely useless, because I need switching between users while notes client is running (so multi user installation does not solve the problem). Mails are delivered properly, and if I set NewMailSeqNum to 0 the notification appears - of course until I switch to another user who has e.g. much more mails.

Is there any setting that enables generating and recognizing NewMailSeqNum for each location? I tried to write it manually in Notes.ini for each location, but Notes Client doesn’t seem to recognize it.
