Exchange 2007 addressbook quirk

Getting the following error downloading the addressbook with Outlook 2003 and Exchange 2007Task ‘Microsoft Exchange Server’ reported error (0×8004010F) : ‘The operation failed. An object could not be found.’ To debug OAB creation in Exchange 2007 you need to turn up the Eventlogging level for the OABTodo so do the following in Powershell.

Get Current Exchange OAB Eventlogging level.Get-EventLogLevel “MSExchangeSA\OAL Generator” Set-EventLogLevel -Identity “MSExchangeSA\OAL Generator” –Level Expert

Remember to disable the logging when you are finished troubleshooting.

Set-EventLogLevel -Identity “MSExchangeSA\OAL Generator” –Level Lowest

 In the end i found two accounts with invalid smtp addresses which the logs identifed easily.

Exchange 2007 Internet STMP Connectivity

Setup SMTP mail receiver

new-receiveconnector -Name ‘Receive from Internet’ -Bindings 0.0.0.0:25 -RemoteIPRanges 0.0.0.0-255.255.255.255 -permissionGroups “AnonymousUsers,ExchangeServers,ExchangeLegacyServers,AnonymousUsers”

Setup Receive MAX Message size 25MB

set-receiveconnector ‘Receive from Internet’ -MaxMessageSize 25Mb

Setup STMP mail sender deliver by DNS resolution

new-SendConnector -Name ‘Sent to Internet’ -Usage ‘Internet’ -AddressSpaces ’smtp:*;1′ -ForceHELO $true -Fqdn mail.domain.com.au -DNSRoutingEnabled $true -UseExternalDNSServersEnabled $false -SourceTransportServers ‘SERVER-EX01′

Setup STMP mail sender deliver using Smarthost

new-SendConnector -Name ‘Sent to Internet’ -Usage ‘Internet’ -AddressSpaces ’smtp:*;1′ -ForceHELO $true -Fqdn mail.domain.com.au -DNSRoutingEnabled $false -SmartHosts ‘[192.168.0.5]‘ -SmartHostAuthMechanism ‘None’ -UseExternalDNSServersEnabled $false -SourceTransportServers ‘SERVER-EX01′

Obviously replace the server name, fqdn and smarthost in the scripts.

Vista network woes

We are running a few vista machines internally at work, a month or so ago, they started to drop off the network randomly so the users reported. Later I found that it was only their connections to the network shares dropping. Exchange, Internet Access everything else was unaffected. I was baffled as to what it could be. We were using DFS to map the network drives. I found that I could go to \\servername\share but not the \\namespace\data\share path

Anyway I was googleing for answers as any resourceful tech does.

I came across this Microsoft KB Article 933860.

DFS failover does not occur when a client computer that is running Windows Vista tries to connect to a DFS root server that is unavailable, and you receive an error message: “System error 1214 has occurred”

Now these were not the exact symptom’s I was experiencing, but sounded similar. Anyway I contacted MS for the hotfix’s for Vista x86 and x64, and the issue is now resolved.
