Outlook 2010 Clients in non cached mode forced offline mode

I have a strange situation here with either outlook or exchange 2010.

On an outlook 2010 machine (and not all of them), you take outlook out of cached mode it goes offline.  You can not force it back online and its grayed out.

If I place the client back into cached mode reopen outlook, goes back online.

I checked in exchange on my particular test subjects and exchange in all instances was _NOT_ configured to prevent a connection from outlook in non-cached mode meaning the client was allowed to connect either way.

This affects any client whether outside or inside (outside assumes rpc over http).

Have anyone seen this? and if so what was done to correct this issue?  I see absolutely no policy to prevent this in our domain at all. If you have a check list I could follow to confirm this ill be happy to do that too.

Thanks!

locally on the machine

%userprofile%\appdata\roaming\Microsoft\outlook

%userprofile%\appdata\local\Microsoft\outlook

just rename both folders and open outlook without cache mode.
it will rebuild your outlook profile

you can always roll back by rename it back.

Would there be a better way than per client? We have 100s and some are in China... :(

Strange the client I just checked was affected yesterday by it now he can connect, his outbound email is stuck in the outbound queue locally on the computer still though, could this have been a transient problem? If it is how would I prevent it from happening again? Still not sure it is transient yet though.

I am still not seeing this issue again popping its head up...

So I ask if there is a way to know what could cause this to occur?
