A while back I installed Office Communicator 2007 R2 in an R1 environment and interestingly as other sites suggest you can login and use an R1 OCS server with the R2 client.
A number of things transpired and therefore I would strongly recommend that you avoid this in production.
- As you might expect R2 options are not functional
- Office Communicator Phone edition was no longer able to login
- Enterprise Messenger for BlackBerry was also unable to login
- There may be more issues that I have not been able to re-produce
Logic suggests that after logging into an OCS R1 server with the R2 client, a number of database updates are automatically applied. This can be reversed by deleting and re-creating the OCS profile. Curious people should avoid, avoid and avoid! [:)]
