unable to open your default email folders

[Lynn]

Hi,
whenever i switch from wireless to LAN, my outlook always give me this
message:

"Unable to open your default e-mail folders. The Microsoft Exchange Server
computer is not avilable. Either there are network problems or the Microsoft
Exchange Server computer is down for maintenance."

I then need to wait for 30mins to be able to login to Outlook again!
What could be wrong?

thank you

If you reboot after switching, does that remove the problem? It might be an
issue with your Exchange Server remembering the IP address of one interface
and not allowing the other to connect with the same credentials without a
clean disconnect. Of course, I'm grasping at straws here but maybe someone
else can come up with a better answer...

rebooting does not solve this problem
