Our application(IBM Content Collector - ICC) is trying to query PR_HIERARCHY_SERVER property. We use the MSMAPI32.dll, acting as client to Exchange servers. However MAPI call HrGetProp for the property PR_HIERARCHY_SERVER = 0x6633001F fails with MAPI Error 'MAPI_E_INVALID_PARAMETER'.
We noticed the issue is not seen when we use Outlook 2010 as client. Below are all the scenariosand results: 1) ICC with Exchange 2019 : Outlook 2019 : Public folder archiving fails 2) ICC with Exchange Online : Outlook 2019 : Public folder archiving fails 3) ICC with Exchange 2016 : Outlook 2016 : Public folder archiving fails 4) ICC with Exchange 2016 : Outlook 2010 : Public folder archiving works!
Do we have to make any changes to code when using newer Outlook client versions? Kindly provide suggestions as this is a blocker for one of our Customers(env: ICC with Exchange Online : Outlook 365).
