I am running the Hybrid Configuration Wizard on Exchange 2013 CU1 to connect to Office 365.
When prompted to select a certificate, I choose our public wildcard certificate, issued by StartCom (StartSSL).
Unfortunately it is not accepted and I am unable to continue the wizard, presented with the message:
The length of the property is too long. The maximum length is 256 and the length of the value provided is 281.
Looking at the event logs, it appears the Powershell cmdlet 'Set-HybridConfiguration' is being run with the '-TlsCertificateName' option.
When trying to run the cmdlet manually I get the following error:
The length of the property is too long. The maximum length is 256 and the length of the value provided is 281.
+ CategoryInfo : NotSpecified: (:) [Set-HybridConfiguration], DataValidationException
+ FullyQualifiedErrorId : CACC7602,Microsoft.Exchange.Management.SystemConfigurationTasks.SetHybridConfiguration
+ PSComputerName : exchangeserver.internaldomain.local
Unfortunately the string generated using our certificate issuer and common name is 281 characters long, which exceeds the 256 character limit of the cmdlet validation.
Does anyone know of a hotfix to resolve this issue, or some way I can edit the cmdlet to increase the number of characters that are accepted?
