Hello,
I am working on a new version of some software that uses CreateStoreEntryID to
generate an EntryId for a mailbox and OpenMsgStore to connect to the mailbox. I
have recently added AutoDiscover functionality to the software to enable
connecting to Exchange 2013 mail accounts. When I am connecting to mailboxes on
an Exchange 2010 or 2007 server that gets proxied through an exchange 2013
server in the domain I get a MAPI_E_FAILONEPROVIDER back when OpenMsgStore is
called.
Any ideas on how I can get this to work?
