Exchange Error to all user

[Qphan]

We're keep getting this error every morning when our users login to Outlook.

"Your Microsoft Exchange Server is Unvailable"
"Microsoft Outlook" Network problems are preventing connection to the Microsoft Exchange Server computer.

The only happen in the morning. Once they're connected then it's ok for the rest of the day.

Any idea why this happen? I'm not sure if it got to do with the configuration on our Cisco switch or this is the exchange issue.

Thanks in advance

What's your OS & Outlook version? I have users running WinXP & Outlook2002, and they are getting similar errors during the day whenever their laptop comes back from sleep mode. Are your computers maybe going to sleep instead of shutting down at night?

When they come back from sleep, they receive this message plus a 2nd (big) message box:
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.

Sounds like the Power management settings for those machines are set to trun the Nic card off.
