Add an Attribute field in Active Directory User Creation (msExchRecipientTypeDetails)

[Safemode]

In the Attributes section, would it be possible to add a field for the msExchRecipientTypeDetails attribute? Typically it's set to 0 by default, and after doing a support call with MS, found out that it can cause issues with DirSync/ADSync not correctly syncing users into distribution groups in O365 unless that attribute was set to 1 and then re-synced, so being able to set it to 1 from the get-go would be very helpful
