I have an Outlook Add-in. In Outlook 2016 (Office 365 desktop version) it will not load. 32 bit Office install on Windows 10 64 bit. It appears that the VSTO runtime itself is not loading. The add-in does not appear. It doesn't appear in the disabled add-ins, nor in the Manage Add-ins anywhere to be enabled.
Is your Dynamics CRM for Outlook not working? If you are a like me and use Dynamics CRM for Outlook it’s likely that you’ve come across some odd issues with performance or Outlook not working as you expect it to. Restart Outlook. Close Outlook, wait for 5 seconds, then start it again. Enable Disabled Add-in. Select Disabled Items in the drop-down at the bottom of this window, next to the Go button. Select the Add-in which you would like to re-enable. Click Enable in the lower-left corner of this window. Restart Outlook. Close Outlook, wait for 5 seconds, then start it again. Skype for Business add-in not loading on Startup. The Skype for Business plugin in Outlook keeps coming up 'unloaded' for this user. If I click the checkbox next to it, it changes to 'loaded', but not 'load on startup' which is what I want. I have tried/looked at: Checked disabled plugins, nothing listed. Removed/added plugin as administrator.
The add-in registry entry for being always enabled is correctly added. I have verified that the correct .NET version and the VSTO runtime are all installed. I have set
and receive no data back from them.
I have also verified that the registry keys are correct. LoadBehavior is set to 3 and Manifest is pointing to the correctly installed file.
What is even more curious is that it did load at one point and worked fine, but seemingly all of a sudden it will not.
Has anyone run into this or know anything I can check to see what is going on?

In the event anyone runs into this, here are the steps used to solve the problem for me.
- Uninstall my add-in
- Uninstall the VSTO runtime
- Uninstall Outlook, including any non-2016 components if any remain
- Reinstall Outlook (2016 should have the run time)
- Reinstall the add-in
It's a pain, but it worked.

Office Outlook is certainly the best desktop email client out there for Windows operating system. I have been using Outlook for the past few months, and all I can say is that it’s hard to switch to other email clients once you start using Outlook.

C:UsersUserNameAppDataLocalMicrosoftOutlook
In the above path, “C” is the drive where Windows is installed and UserName is your user account name.
NOTE: If you can’t see AppData folder, it’s because the folder is hidden by default. In the File Explorer, click View, and then check Hidden items to view the folder.
