andrejg 1 Posted May 6, 2022 I came across problems with my MAPI implementation once moving code to 64-bit and the only solution I could find is your unit @Attila Kovacs so thank you!! 👍 1 Share this post Link to post
JonRobertson 81 Posted April 8 (edited) We have apps that use MAPI to start an email that do not work if the user has switched to New Outlook. And new Office 365 installations now install New Outlook without an option to use Classic Outlook. My understanding is that you can still install Classic Outlook, but using a separate download. After some investigation, we discovered that calling MAPISendMailW with the MAPI_DIALOG_MODELESS flag does work with New Outlook. And using Attila's unit made this a breeze. Thanks Attila!
