Problem with sharing free/busy across two orgs

    Domanda

  • Hello,


    for our migration I want to allow share free/busy. There are two forrests (with a trust), lets call them local.old and local.new


    Mailboxes in "local.old" have these E-Mail-Addresses
    - firstname.lastname@domain.de
    - vorname.nachname@local.old


    Mailuser in "local.neu" have these E-Mail-Addresses
    - firstname.lastname@domain.de
    - firstname.lastname@local.new
    - firstname.lastname@local.old (as "external addresse")


    On the Exchange in local.new I've used Add-AvailabilityAddressSpace to add local.old. On the Exchange in local.old I exported the autodiscover config with Export-AutoDiscoverConfig to exchange.local.new.

    Exchange 2010 seems to use this configuration, but not correctly, because I get this two eventlog entries:
    Process w3wp.exe () (PID=****). Exchange Active Directory Provider could not find an available domain controller in domain DC=local,DC=old. This event may be caused by network connectivity issues or configured incorrectly DNS server. This event may also occur if you have not configured correctly your multiple Active Directory sites.

    (Can not find correct english version of this message, it's translated)
    Process ****: Can not establish a  Active Directory connection in the remote forest local.old. Please verify the attribut 'ServiceBinding' of the Service-Connection-Point-Object CN=local.old,CN=Microsoft Exchange Autodiscover,CN=Services,CN=Configuration,DC=local,DC=new in  Active Directory is configured correctly. Connection error Microsoft.Exchange.Data.Directory.ADTransientException: Could not find any available Domain Controller in domain DC=local,DC=old.
    bei Microsoft.Exchange.Data.Directory.DSAccessTopologyProvider.GetServerFromDomainDN(String distinguishedName, NetworkCredential credential)
    bei Microsoft.Exchange.Data.Directory.SystemConfiguration.ADSystemConfigurationSession.CreateRemoteForestSession(String fqdn, NetworkCredential credential)
    bei Microsoft.Exchange.InfoWorker.Common.Availability.ScpSearch.<>c__DisplayClass6.b__1()
    bei Microsoft.Exchange.InfoWorker.Common.Availability.ScpSearch.PerformRetryableAdOperation(String operationDescription, RetryableAdOperation operation)

    The DCs are working proer. I used dcdiag on the 2010 Exchange to check a DC of local.old and the result is OK


    I hope someone has a good idea - i haven't


    Kind regards,
    Dennis

    Add-AvailabilityAddressSpace -ForestName e2k7forest.dk -AccessMethod PerUserFB -UseServiceAccount $true

    2.Set Required Permissions in Exchange Forest 2 (Exchange 2007)

    Get-ClientAccessServer| Add-AdPermission -AccessRights ExtendedRight -ExtendedRights
    "ms-exch-epi-token-serialization" -User "e2k10forest.dk\ExchangeServers"

    3.Configuring Autodiscover support for Exchange forest 2 in Exchange Forest 1

    4. Create autodiscover DNS record in 2007 forest

  • Sorry, but didn't helped for me. I can't access the calendar of a person in the E2K7 forest. Outlook 2010 shows a message "could not refresh" and I can't see any error in the E2K10 eventlog.

    Any idea?

  • Hi,

    Can you finish the configuration of calendar sharing between these two forest?

  • No, same state... Outlook says that the calendar can't be updated but I don't get any error on the E2K7 or E2K10.

    I'll leave the office for vacation, but will trigger this topic as soon as possible :) In the time between: all ideas are welcome :)

  • OK, I've reviewed my configuration and used Test-OutlookWebServices to test my configuration. But I get an error for AS:

    ErrorProxyRequestProcessingFailed: Unable to send cross-forest request for mailbox <***>SMTP:***.***@local.old because of invalid configuration., inner exception: AvailabilityAddressSpace 'local.old' couldn't be used because the Autodiscover endpoint couldn't be discovered.

    I've used Export-AutoDiscoverConfig to export the SCP from local.old to local.new (for local.old and domain.tld). Is the SCP stored in the correct location? The DNs are:

    CN=local.old,CN=Microsoft Exchange Autodiscover,CN=Services,CN=Configuration,DC=local,DC=new
    CN=domain.tld,CN=Microsoft Exchange Autodiscover,CN=Services,CN=Configuration,DC=local,DC=new

    Every other test of Test-OutlookWebServices is successful, only this one failes.

    I've no idea what happens...

  • This works - after replacing the self-signed certificate on the E2K7 with one singed by an internal CA. Now I've a new problem, but I'll open a new question for it. Thanks for all :)
