Hello!

Today I've bumped into a strange issue, when finishing installation of Exchange Server 2013SP1: the first time I open ECP it opens successfully, the second - it shows (after entering login/password) the following:

X-OWA-Error: Microsoft.Exchange.Data.Storage.MailboxOfflineException
X-OWA-Version: 15.0.847.32
X-FEServer: EXCH1
X-BEServer: EXCH1
Date: 4/17/2015 2:56:46 PM

I have two host machines on which I'm testing various server/network configurations and I used these hosts/VMs many times for the various Exchange installations and I've never seen such issues. All my steps are:

1) Install DC (vm)
2) Install Exchange 2013 SP1
3) Run ECP for the first time = ok
4) Close ECP
5) Run ECP for the second time = error (I have even never rebooted the server after finishing installation)
.....

6) Run ECP for the n-th time = ok (optionally)

I reinstalled DC and Exchange VMs twice  - the result is the same...

???

Thank you in advance,

Michael

Hi Michael,

From your description, I recommend you check if there is any issue with network connectivity. What's more, please carry out service health checks and determine that the services are restored.

Hope this can be helpful to you.

Best regards,
