Dear Anyone,

We are using Exchange 2010 server, recently there has a problem for OWA login and got the result message "Your mailbox appears to be unavailable. Try to access it again in 10 seconds. If you see this error again, contact your helpdesk"

Everytime we need to reboot frontend and backend exchange server.

Can anyone help us how to solve this problem?

Many Thanks

Hi,

If some required Exchange service(s) are not running, this can happen. Next time, before restarting the server, do a troubleshooting.

1. Use the following cmdlet to check the system health (service health)

Get-ExchangeServer | Test-ServiceHealth | ft Role,RequiredServicesRunning -

2. Verify that all the required Exchange services are in running status.

3. If not, check event viewer and find the reason for the service has stopped.

3. Use the following cmdlet to start the services again

Test-ServiceHealth | Select ServicesNotRunning | foreach { Start-Service $_.ServicesNotRunning }

4. Again, check if some of the services are not started. Find the reason from event viewer

Thanks for your reply.

Every happened this event, I had checked Test-ServiceHealth, there is nothing in [ServiceNotRunning], and I also check event viewer, cannot find which event is related.

can you give me more hints? beside reboot server, can I do anthing such restart which service I can solve temporary.

Thanks

Hi,

As a temporary solution, you can try restarting store service and/or transport service.

Hi chan,

Thank you for your question.

In addition ManUs suggestion, we could run the following command when we could not logon OWA, then check if the issue persist.

Test-ServiceHealth | select ServicesNotRunning | Foreach { Start-Service $_.ServiceNotRunning }

This command proceed as follow :

1.        Validate status of Microsoft Exchange server services based on the installed role(s)
2.        From services statuses it selects those not running services
3.        Finally , it initiates a start-service request for each of not running services

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
