Hi bengxiong,

What does the event viewer say about why the Information Store stopped?
Dear beng
There could be plenty of factors involved in this situation
Check out this link as it addresses many factors;
In addition to checking the event viewer as JoWickerman suggested.  Check the queue to see if you have email stuck there (Exchange system manager > Administrative Groups > first administrative group > servers > ServerName > Queues).

Also run ISINTEG fix -test alltests

I already check the event viewer there's nothing about the issue. yes, I check the Queues and there are like alot of emails that  are in there. I tried to freeze and force it but nothing happen.
Have you contacted your ISP to make sure that they don't have issues?
Make sure that all the services are started.  Then I would start with the easiest thing first, reboot the server. If that doesn't work then I would check your DNS settings and your connection to the internet.

I already reboot both of my server. The PDC and exchange. I checked the DNS and everything works fine.
Did you contact your ISP?

Also did you have a chance to run ISINTEG to repair any issues with the server?
bengxiongAuthor Commented:
Yes, I contact my isp and they said there's nothing wrong on their  end.  I guess I will have to do some more troubleshooting.

Confirm that you can access the internet from the server?

Have you recently installed or uninstalled any email filtering software?

Make sure that the Simple mail transport service is started as well as all the MS Exchange services that are set to start automatically.

Double check the Application event log for errors.

Thanks guys for your help.  I delete all of the emails that are in the Queues one by one and restart all of the exchange services and now it work. It must have something to do with my isp because all of my email went on the blacklist.
Glad to hear it's working again, good job.
