Hi,
one of my customers has a problem
(only one... so maybe it´s not the problem of my add-in ;-) )
my add-in is not loaded.

It´s deactivated by outlook. If I set the hook to activate "files->options->Add-Ins-> commadd-ins" ... after the next startup it´s deactivated again. (Loadbehaviour is 3) A adxloader.log is not created.

Do you have an idea where I can search for the solution? The log of the installation seems okay. It ended with success :-)

Hello Bernd,

First off, let the customer navigate to File | Info | Manage COM Add-ins to check if your add-in is declared slow.

Also, we saw similar issues with add-ins switched from per-machine to per-user (or vice versa) and the older add-in version still being installed. This creates two sets of registry keys pointing to the per-user and per-machine versions. Check the paths the log reports.

Yes, the add-in is declared slow.
Under that entry, I can check "Add-in always activate" to ON.

If I renew the window, it´s again deactivated and I can check again "always activate" ...

Hmmm seems that Outlook don´t want to follow my "orders" ;-)

You must start Outlook with Admin rights to change this behaviour otherwise the registry entry will not be changed. You can also change the registry entry manual with admin rights.

I´ve done this as administrator ... I found it:

The Add-In was listed under
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Resiliency\CrashingAddinList
After deleting the entry everything is fine now :-)

Thank you!
