Could not convert property DisabledEmailAddressTemplates - Exchange 2003 to 2010 Migration

Performing an Exchange 2003 to 2010 migration, with later plans to migrate to Office 365.

While performing Exchange 2010 SP3 install on a new server, I get this error during install: (I removed the domain name used)

Beginning processing New-AcceptedDomain -Name:'' -DomainName:'' -DomainType:'Authoritative'
[07/14/2014 19:30:30.0795] [2] Processing object "".
[07/14/2014 19:30:30.0827] [2] Could not convert property DisabledEmailAddressTemplates to type ProxyAddressTemplate. Error while converting string ':OPTIO' to result type Microsoft.Exchange.Data.ProxyAddressTemplate: E-mail address template ":OPTIO" has an empty prefix or an empty address template string. Property Name: DisabledEmailAddressTemplates

I get this error repeated on ALL accepted e-mail domains.  I can't see any reference to :OPTIO in any e-mail recepient policy...

Also, ran a report to export all SMTP addresses used (with alias) and nothing...

I am stuck...any ideas?

Probably you will have to search for the term in question in your case is OPTIO.

 You could try to use ldifde to find, use this command against your domain and see if OPTIO term appear.

 ldifde -f badproxies.txt -d "dc=yourdomain,dc=com" -l proxyaddresses -r "(proxyaddresses=*smtp:*OPTIO*@*)"

 This will generate a text file with info about the term if exists on you AD you also can use ldifde to query ldap and try to find that term by other ways. You could see more info about ldifde here LDIFDE

Thank you for the info...
Unfortunately, it only found 1 item, a disabled account.  Removed the account (not needed) and still get the SAME error on the PrepareAD portion of the setup of Exchange 2010

Found the solution...
There was an entry for :XXX in the DisabledGatewayProxy for one of the e-mail templates.  Removed that and all is well.

You need to use ADSIEdit in order to find it...
