Dear All,

I'm running Exchange Server 2013 CU8 on top of fully patched Windows Server 2012 R2 Standard that right now is co-existing with Exchange 2010 SP3 with the latest rollup on top of Windows Server 2008 R2 SP1 with latest updates too.

I found that when I'm running the "Get-App" cmdlet from EMS on Exchange 2013, I get the following error:

The request failed. The remote server returned an error: (403) Forbidden. (There's a screenshot too).

Well, I search the web for some answers before posting here and here's what I've done to summarize my activity with no luck of solving this issue:

1. Running Set-OrganizationConfig with all the EWS flags are blank except EWSEnabled which is true.

2. Reset the EWS virtual directories on both Exchange 2010 & 2013 (Reset = Delete & Recreate).

3. Try to replace my internal PKI cert with the 'Microsoft Exchange' Self-signed certificate back and try running the command again with no result (both for Default Web Site & Back End @IIS).

4. Try to surf using Internet Explorer on the server to https://serverhostname/OWA & /ECP & /EWS with no luck getting error - "This page can't be displayed" after entering the FQDN - https://serverhostname.domain.com/OWA & /ECP ... I'm getting to the interface (I mentioned that because I'm thinking this may relate to this issue).

5. Restart :-). 

Please assist,

Thanks!

Do you have the required rights as shown in "Apps for Outlook" here:

Hi Netanel,

Agree with Ed, You need to be assigned permissions before you can run this cmdlet. 

You may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Apps for Outlook" entry in the Recipients Permissions topic.

Best regards,

I got all the required permissions and still no luck and same error. any suggestions?

Hi Netanel,

Please try to run EMS(Exchange management shell) as an administrator and check if any helps:

To start a EMS as an administrator

Right-click EMS, and then click Run as administrator.

Best regards,

Hi Niko,

I'd tried that and still the same error. :-(
