When migrating a customer to Office 365 I had a problem opening the mail control panel applet. It simply showed the error message “Application not found”:
This seemed to be occurring on 64-Bit machines where we had installed 32-Bit Office 2016 from the Office 365 portal.
I found two workarounds for this:
Workaround One: Run the mail applet directly from the command line
- Press Windows Key + R to bring up the run dialog
- Paste the following:
C:\Program Files (x86)\Microsoft Office\root\Office16\MLCFG32.CPL
Workaround Two: Run the mail applet from Outlook 2016
If you in Outlook you can run the control panel mail applet from within Outlook by going to File and clicking on account settings, at the bottom of the account settings drop down you should see a “Manage Profiles” button, which will take you into the mail applet.
I would like to find a proper solution for why this is happening, so if anyone comes across a solution, I’d appreciate it if you share your solution.

I was able to fix this by searching for MLCFG32.cpl, and modifying the paths that had somehow gotten messed up:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{A0D4CD32-5D5D-4f72-BAAA-767A7AD6BAC5}]
@=”Mail”
“LocalizedString”=”Mail (Microsoft Outlook 2016)”
“InfoTip”=”Microsoft Outlook Profiles”
“System.ControlPanel.Category”=”9″
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{A0D4CD32-5D5D-4f72-BAAA-767A7AD6BAC5}\DefaultIcon]
@=”C:\\Program Files (x86)\\Microsoft Office\\root\\Office16\\MLCFG32.CPL,0″
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{A0D4CD32-5D5D-4f72-BAAA-767A7AD6BAC5}\shell]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{A0D4CD32-5D5D-4f72-BAAA-767A7AD6BAC5}\shell\open]

Still an issue up until today on Windows 10 Pro v2004 with Office 2019 v.2006.
Talk about a complete cluster***, even the proposed fixes and workaround sometimes don’t even work either (depending on whether install is C2R or MSI and if 32-bit vs 64-bit. Most reliable workaround is simply going to Outlook > File > Account Settings > Manage Profiles.
This really reflects poorly on Microsoft’s level of software review (not that I’m surprised any bit from using their products for over 10 years professionally), a complete lack of QA, and utter incompetence at resolving bugs that have been an issue for over 3 years. It’s pretty shameful.
