qbmapi64 ERROR!!!

Adding another voice to this thread as it is happening to us as well.  We have QB installed on 2 servers both are Windows Server 2019.  I tried a repair of QB using the Tools Hub and saw it reinstalled the C++ redistr as needed, but it did not help.

I can also confirm that this fix worked for us:

1. Close QuickBooks.

2. Copy D3DCompiler_47.dll from C:\Windows\System32\.

3. Paste into the QuickBooks installation folder (C:\Program Files\Intuit\Quickbooks 2024\).

4. Open QuickBooks again. The error should not be present.

qbmapi64 ERROR!!!

I ran into the same error. Everything was working fine until I updated QuickBooks 24 on server 2019. The mapi64 error suggests it had to do with email. What I found out worked was after the update, I uninstalled Office 64 bit  rebooted and then installed Office 32 bit. The error went away and everything worked as it should again. It seems to be an issue with 64bit Office and QuickBooks after the update. Hope that helps someone else.
