Is Lotus Notes MAPI compliant?
Yep, the equivalent. Which versions of Lotus Notes provide MAPI support? All 32-bit versions of Lotus Notes from 4.5 onwards provide the necessary .dll. However, version 4.5.4 works reliably in all situations. Version 4.6 and 4.6a were missing some fixes to the MAPI support that were in 4.5.4 and so do not work properly. We don’t know about later versions. Starting with Notes Release 5.0.5, Lotus delivers iNotes Access for Microsoft Outlook, which includes calendar capability as well as mail features. It is simpler to install and configure than the earlier MAPI provider. http://www.slipstick.com/addins/services/lotusnotes.
