If Openchange provisioning of 4087 branch version is made by script from 4087 version, there is error:
[+] Step 1: Register Exchange OIDs
ERROR: no 'top' class in loaded schema
[!] error while provisioning the prefixMap: (31, 'WERR_GENERAL_FAILURE')
but there are not troubles while openning of Global address book in MS Outlook.

Do you mean that the issue is now fixed for you?

I don' t know exactly at the moment whether it is affected to something in working. But I suppose, some additional investigation is necassary, I think rather not solved or fixed.

While provisioning of Openchange of 4090 branch version by provision script from the version, there has been new error message:

NOTE: This operation can take several minutes
[+] Step 1: Register Exchange OIDs
ERROR: no subClassOf 'serviceAdministrationPoint' for 'rRASAdministrationConnectionPoint'
[!] error while provisioning the prefixMap: (31, 'WERR_GENERAL_FAILURE')

And again there is error while provisioning but there are not any visible errors while working after provisioning.

The same error is in 4106 version:
ERROR: no subClassOf 'serviceAdministrationPoint' for
rRASAdministrationConnectionPoint'
[!] error while provisioning the prefixMap: (31, 'WERR_GENERAL_FAILURE')

I have the same error with the latest version.
