This event simply reads Network Problems are preventing connection to Microsoft Exchange. The user is also notified via the balloon that the connection status has changed. Event ID 26 is then logged which is Connection to Microsoft Exchange has been lost. Outlook will restore the connection when possible. Followed by another event id 26 saying Connection to Microsoft Exchange has been restored. All of this happens within a couple of seconds generally. Users when sending mail will occasionally get the balloon – Outlook is trying to receive data from the exchange server and then Connection has been restored. With logging switched on I managed to get these Event ID 19’s as well. Rpc call (Unknown) on transport (ncacn_ip_tcp) to server (EXserver.mydomain.local) failed with error code (6be) after waiting (0) ms; eeInfo (Block (0), Error = 6be, Version = 1, GeneratingComponent = 2, DetectionLocation = 6ae, Flags = 0, Params = 1, [Param (0) Type = eeptLongVal, Value = 1], Block (1), Error = c0021012, Version = 1, GeneratingComponent = 2, DetectionLocation = 6b8, Flag
2007 and throughout the day continuly recieve: "Event id: 26 Connection to Microsoft Exchange has been lost. Outlook will restore the connection when possible" and when this happens: "Event ID: 19 Rpc call (EcDoRpcExt) on transport (ncacn_ip_tcp) to server (exchange02.domain.COM) failed with error code (6) after waiting (0) ms; eeInfo (none)" at about the same time. In Outlook the balloon notification will pop up letting the users know that Outlook has lost its connection with the Exchange server. It only happens with mailboxes on this Excahnge server, I can move the mailboxes back https://social.technet.microsoft.com/Forums/exchange/en-US/c217b15f-02db-40f5-b92b-ae1270069995/outlook-2010-random-status-connection-changes?forum=exchangesvrclientslegacy to another server and the issue goes away for that mailbox. My RPC Averaged Latency, RPC Operations/Sec and RPC Requests are generally under what Microsoft's high thresholds are. There are 3 shared mailboxes on this server that 100 or so users connect to where their mailboxes are housed on another server. Other than these 3 shared mailboxes there are only 3 user mailboxes and all three http://www.networksteve.com/exchange/topic.php/Outlook_Disconnecting/?TopicId=17443&Posts=22 receive these disconnects and errors all day long. Any ideas? July 13th, 2010 4:09pm Can u run check-mapiconnectivity test on that server. Next is the error apearing when the users are using RPC over HTTPS or when their are pure MAPI clinents. Are the MBX servers all in the same subnet, have u checked that RPC servive is working on the problematic server. Are the RPC ports open for the users to connect to the server. Are all your users on that server having the same problem, its again me asking if their connectiong like MAPI or HTTPS/RPC. Also run ExBPA and check for errors. Are their any system errors on the server indicating a hardware error? Free Windows Admin Tool Kit Click here and download it now July 13th, 2010 4:29pm Pure MAPI no RPC over HTTPS. Yes, all user maliboxes on that server have the issue. Yes, all mailbox servers are on the same subnet, connected to the same switch. RPC service is working on the server and as far as I know all default RPC ports are open. No system errors in the event viewer. ExBPA looks good. However, the Exchange Performance Troubleshoot

Have reverse Proxy through ISA server 2006 sp1 on win2k3sp2 . failed with OWA , /Exchange to E2K3 mailboxes and rpc works fine . However 2 or 3 times in a day , the Outlook 2007 client on RPC disconnects with connection status in outlook shows directory status as disconnected ,Mail is connected , however mails can be sent & recived but RPC connection becomes very slow . If I set up RPC over HTTPS bypassing ISA server it works fine failed with error . NETstat command in ISA server shows all connections to DC's established . Any ideas on what could be the casue.
