Remote Access

hi all

We are having lotus domino server R6.0.1. and

the clients we have installed is R5.0.8. becos the space constraint of the PCs. Some of the users are having remote access facility using internet browser.Initially the database design template is R6.In this situation the remote users having a option called logout under mail option,after usage users can able to choose logout option to comeout.In the client part they are not able to create TODO items and under Tool option,Archive Settings and New Memo using Stationery options only available. If i change the database design to R5, users can able to create in TODO and they are having preferences,out of office,add sender to addressbook and new memo using stationery options.what is the remedy for this and the server database design is R6,users database design is mixing of R5 and R6.Is that create any database corruption problem ? and we want clients database design would be R5 in the same time we need logout option during remote access.

requesting all to give me a solution at the earliest
