ziemekb:Is anybody know if MSFT will verify compatibilty HMC 4.5 with Exchange 2007 SP2?
Unknown. Probably you have to call MS PSS and ask about it.
In general, HMC 4.5 has issues with Exchange 2007 SP2. So far, I found that Exchange 2007 Provider can't create PF:
<response>
<errorContext description="A parameter cannot be found that matches parameter name 'StorageQuota'.
Cmdlet='Set-PublicFolder'
DomainController='ad99-dc-01.ad99.test.com'
Identity='\0_HMC45.com'"
code="0x80131600"
executeSeqNo="217">
<errorSource namespace="Exchange 2007 Provider"
procedure="CreateFolder"/>
<errorSource namespace="Managed Email 2007"
procedure="CreateFolder"/>
<errorSource namespace="Softcom Utils 2007"
procedure="CreateRootPublicFolder"/>
</errorContext>
</response>
Microsoft has changed the name of the parameter, responsible for warning level, in Set-PublicFolder cmdlet. Before it was StorageQuota, now it is IssueWarningQuota. As a result, Exchange 2007 provider in HMC 4.5 is unable to call Set-PublicFolder whiсh is a part on provider’s CreateFolder method.
I hope to have couple spare hours this week to call MS PSS and ask about a fix.
