When you work offline, you may receive following message several times:
Outlook is retrieving data from the Microsoft Exchange Server server_name.
This behavior occurs when your connection to your Exchange Server is through RPC/HTTP transport protocol. Outlook cannot detect global catalog connections directly to the Exchange Server; Outlook can detect only global catalog connections to your RPCProxy server. As each global catalog connection to the RPCProxy server, you receive the warning message that is described in the "Symptoms" section of this article.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
When you receive the warning message, you can cancel the request or minimize the message until Outlook closes the message automatically.
To determine the status for each of the servers that you are connected to, follow these steps:
In the notification area, right-click the Network Connection icon for the server you want to check.
On the General tab, note the Connection values.
Repeat steps 1 through 3 for each server that you have a connection to.
