Hello Experts , <br />
<br />
<br />
After an iSCSI switch outage we lost connection into our storage system and also our Exchange SCC infrastructure lost his mailbox storage. We finish with the restoration of the services and the volumes and clients have connectivity problems , <br />
<br />
Although mail flow works without problems and outlook is connected without problem &nbsp;, clients complaint about connectivity issues when they are doing common things like browsing GAL , trying to send appointment to someone else , etc .The error they take is &quot;&nbsp;the connection to the microsoft exchange is unaavailable. Outlook must be online or connected to complete this action &quot;&nbsp;<br />
<br />
Also i cannot longer setup in outlook new users. <br />
<br />
<br />
Thanks

Exchange 2007 - Strange problems after outage of storage

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
