What is going on with Outlook for Windows? For years, it froze its entire UI whenever there was some network lag on the IMAP server, and the recent improvements for Outlook strangely focus only on their Mac, web, and mobile versions. Does the Windows version still have a future? It seems to be stuck in some maintenance limbo.

I think it is probably a very large program but does have some legacy cruft they probably can't fix easily. Either because backwards compatibility for COM or due to that if you rewrite something to be async the callers also need to be async and callee need to be non-blocking[0].

However, Outlook is very much actively developed and myself being a Premium user am receiving new features now and then, like UI refreshes etc.

(0xC000005 == STATUS_ACCESS_VIOLATION, accessing a memory address that couldn't be accessed, ie a segfault.)

I wonder if this is an attack vector. On one hand it isn't because usually the HTTP traffic of Exchange is encrypted, on the other hand it is a crash triggered by a remote condition.

Yup! I just updated Windows and got a crash. Relaunched it and it was ok

    Faulting application name: OUTLOOK.EXE, version: 
    16.0.13001.20266, time stamp: 0x5ef2a169
    Faulting module name: mso98win32client.dll, version: 0.0.0.0, time stamp: 0x5ef2771f
    Exception code: 0xc0000005
    Fault offset: 0x00000000000beef2
    Faulting process id: 0x3be0
    Faulting application start time: 0x01d65ad25f628bf7

    Office\root\Office16\OUTLOOK.EXE
    Faulting module path: C:\Program Files\Common Files\Microsoft Shared\Office16\mso98win32client.dll
It's also very nice how easy it is to roll back one program on Windows!
