Description
I'm running into an issue where my old/dismissed reminders come back every time I restart outlook. I'm trying to resolve the issue per resolution 2 on https://learn.microsoft.com/en-us/exchange/troubleshoot/calendars/cannot-dismiss-outlook-calendar-reminders. When I try to delete the reminders folder via mfcmapi (64-bit version 24.0.24100.06) I get the following error:
Error:
Code: MAPI_E_UNKNOWN_FLAGS == 0x80040106
Function lpParentFolder->DeleteFolder( static_cast(itemEID.size()), mapi::toEntryID(itemEID), lpProgress ? reinterpret_cast<ULONG_PTR>(m_hWnd) : NULL, lpProgress, ulFlags)
File C:__w\1\s\MFCMAPI\UI\Dialogs\HierarchyTable\MsgStoreDlg.cpp
Line 797

Research direction
Start at UI/Dialogs/HierarchyTable/MsgStoreDlg.cpp line 797, where the DeleteFolder call reports MAPI_E_UNKNOWN_FLAGS. Reproduce the error by deleting the reminders folder through the 64-bit MFCMAPI build, then trace the flags passed to that call and determine the expected behavior; the issue has no stated acceptance criteria.
