Sync: Enterprise at work, Outlook at home

Is it possible to sync between the 2 servers?
I use Enterprise at work with my lotus notes but want to be able to update my calendar from my home computer and sync it with the same blackberry that gets updated from lotus notes/work?

Would the calendars combine on the blackberry then on to lotus notes?
Any advice would be appreciated.

I also want to use it as a back up in case my work computer crashes on me. I will always have contacts saved at home too.

If so..what version of desktop do I install at home (enterprise or personal)?

Thanks

I don't have BES, just BIS, but I stumbled upon a previous post discussing this issue. It may shed some light on your situation.

I have the same problem - I sync contacts/apmts/email with my office BES - but need to be able to sync at home (to update outlook contacts there -- and other things such a ewallet, reader,etc.) --(so some things are on work computer, and some are stricly on home PC) -- I am afraid to try to do this because I don't want to wipe the connection to BES - it was such a pain to get that function going well. Anybody have tips on how to set this up ? Thanks for listening.
