The following error occurs during Public Folder gathering:
"HrMAPIOpenSubfolderEx() returned the error 0x800B0001 while opening Public folder Name. The folder was not found.Probable Cause: You do not have administrative access to the server. Object: Public Folder Name Context: Retrieving the Article Index folder from the message store.; Server:/o=XXX/ou=XXX/cn=Configuration/cn=Servers/cn=XXX; DC:XXX; GC:XXX; Method: QExchangeWidget::EnumPublicMsgStoreRoot; Calling HrMAPIOpenSubfolderEx();"
This can occur if a folder path contains an invalid character or if one of the folders in the folder path has a backslash in the folder name.
Since HrMAPIOpenSubfolderEx parses the path using a backslash, this would fail to open the folder. The result is that the folder ACL, subfolder count and replica server list will not be gathered.
Check if you can open the properties for the folders when connected to the respective server in Exchange Administrator using the Quest MessageStats Service account.
If this does not work, then Messagestats will not be able to open the folders either.
If this works, please contact Support@Quest.com to open a support case. Please provide more information about these public folders, for instance if they are configured differently, what are the permissions, etc.
