"There was a problem reading one or more of your reminders. Some reminders may not appear network problems are preventing connection to the Microsoft exchange server computer"

Search your PC for outlook.exe.  Once you know where it is, browse to that location through a command prompt and run:

outlook /cleanreminders

I've already done that, still has the same issue. :(

Take a look at the network connection.  Are you still able to do other network functions after this happens?  Does it happen to anyone else on the same hub?  If you change your connection to a different hub connection does it stop?  Is it only during high usage times?

It was a corrupt reoccuring calendar entry.

Thanks for pointing me in the right direction Marc.

Any tips on how you resolved this.  I have the exact same problem.
