Many users of Outlook 2003 with mailboxes on an Exchange 2003 Server provided report single or together of the following error messages when they attempted to explore single or many Exchange 2010 user Calendars.
Unable to display the folder. The information store could not be opened.
The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action.

Issues with MS outlook exchange server
This error usually arises when you access your Outlook Email offline. To resolve this issue, Outlook need
to be synchronized. Here’s what you need to do.
Open Microsoft Outlook.
Synchronize the required Outlook folder.
Select the Send/Receive menu.
Or head to Tools and choose this Folder for the option to synchronize the chosen off-line folder.
Clicking on the Send/Receive menu button, would allow all off-line folders to be synchronized.
Go to Tools menu, followed by Options. To perform automatic synchronization.
Send immediately once connected under Send and Receive must be selected.
Make sure to select on Perform automatic send/receive once exiting.
Now you have got with successfully synchronized Outlook.
If that doesn’t work, another resolution would be to delete the account and then reconfigure your email to Outlook.
