Outlook clients disconnect from server - 14.Dec.2010 1:10:56 PM

Hi Guys,

Looking for some help please as im stumped.

We have a client on Exchange 2010 with Outlook 2007 clients.

The exchange server has been faultless to date with this issue as an exception.

2% of the users get disconnected from the exchange around once an hour (its never dead on an hour).

The event ID is 26 on the clients machines and basically says connection lost and then another message saying connection restored. The delay in restoring the connection can be seconds or ultimatley never.

They are using Outlook Anywhere as the server is offsite.

The same company has users with the exact same setup are fine. This can occur in or out of the office and can make life very difficult for them.

Ive checked everything on their machines and am really struggling to get to the bottom of why 2 out of 15 users have this issue. Almost seems like they are disconnecting from the network (which they are not).

The fix so far is to set outlook to offline mode then back to online. This is not ideal. Not sure if this is a server thing (doubtful as no one else has this issue) or local.

Any help much appricated.

Regards

Lee

maybe it's an internet problem.

try this while the user is connected. open a cmd and use this command.

ping -t Server_IP > log.txt

if outlook looses connection see if there is a lost connection in the log file.

The users are all in the same office on the same internet connection. Wish it was that!

still doesn't hurt to check, could be many things, these tests are to rule out possible problems. I said internet connection but, it could be network hardware or with wireless the damn cellphone near the antena or other interference.

If you dont know what the problem is you got to rule out what it's not and narrow it down.

Does it happen at the same time on both computers or at diferrent times?

Different times and its random.

All other network related applications continue to run fine. Both internally and externally. Outlook is not able to reconnect or establish a connection for some period of time, I have been on their machine when this happened and can access everything network related fine.

Its just occured again in fact. THis time I logged in and could ping the server and everything else but HTTP over RPC got stuck trying to disconnect cleanly and as such could not reconnect.

Maybe this is an RPC issue for this user...is there any exchange commands i can to see current connections over RPC?

or check this link.

http://social.technet.microsoft.com/Forums/en-US/exchangesvrclients/thread/2de0bd0e-b684-4e5e-9d03-d47645dc6cb2/

a few questions:

- are cliente systems fully updated?
- are there differences between ppl who are having the problem and the ones who are not?
- have you tried Outlook 2010?
- are you using certifications on clientes? and whats there max time?

1) Yes all updates are applied
2) there were no differences, until i experienced the same disconnection at the roughly one hour interval. Its never dead on an hour, its always around 5-10 mins either side.
3) Havent yet upgraded to 2010, and dont see this as a fix...Althought its my last option!
4) Yes SSL on Outlook Anywhere is a must. No idea how to check there max time though.

You can download office 2010 trial version and see how it works out.

As for the certifications, not sure were that is but you should see what the time out is.

Or reinstall them again on clientes with problems.

Clients are prompted to allow the certificates to be accepted once a month, so assume that is rememebered for 4 weeks.

Not going to install outlook 2010 as a trial on client machines.
