Hi all, Here is my configuration : 2 CAS/Hub servers in a CAS Array, and 3 MBX servers. At the beginning, I used the name ex2010.xxxx.fr, internally and externally. All worked well. I then switch to he.xxxx.fr. I ran all the recommanded cmdlets (Set-OutlookProvider, Set-AutodiscoverVirtualDirectory, ...), but when I perform an online connectivity test (see below), the EXCH provider still shows the old name for Server, ServerDN and MdbDN. Though, ASUrl, OOFUrl, ... are fine. The EXPR provider is fine too. Any idea of how to correct it ? Thanks. <Account> <AccountType>email</AccountType> <Action>settings</Action> <Protocol> <Type>EXCH</Type> <Server>ex2010.xxxx.fr</Server> <ServerDN>/o=HostedExOrg/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=ex2010.xxxx.fr</ServerDN> <ServerVersion>738280F7</ServerVersion> <MdbDN>/o=HostedExOrg/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=ex2010.xxxx.fr/cn=Microsoft Private MDB</MdbDN> <ASUrl>https://he.xxxx.fr/ews/exchange.asmx</ASUrl> <OOFUrl>https://he.xxxx.fr/ews/exchange.asmx</OOFUrl> <OABUrl>https://he.xxxx.fr/oab/2a376136-4931-439d-8cac-ed435305e0f9/</OABUrl> <UMUrl>https://he.xxxx.fr/ews/UM2007Legacy.asmx</UMUrl> <Port>0</Port> Christian G.

Hi , Just to be clear, how to modify EXCH provider ? Would you post detail cmdlet ? The Set-OutlookProvider cmdlet only set global setting. And the EXCH setting references the Exchange RPC protocol that is used internally. This setting includes port settings and the internal URLs for the Exchange services that you have enabled. The EXPR setting references the Exchange HTTP protocol that is used by Outlook Anywhere. This setting includes the external URLs for the Exchange services that you have enabled, which are used by clients that access Exchange from the Internet. Please understand the following article.

Thanks for the replies. Since the databases has been created after the CAS array creation, I thought nothing would need to be done on to them. But I had forgotten to also change the name of the CAS array : Get-ClientAccessArray | Set-ClientAccessArray -Fqdn he.xxxx.frChristian G.
