If you use Copy2Contact with Outlook, a separate component is installed called the Copy2Contact Add-in, which actually works inside Outlook to provide some additional features to the Copy2Contact program itself.
One feature is that the Copy2Contact Add-in allows Copy2Contact to “guess” the email address of a contact if you’ve captured text from an incoming email inside Outlook. If the text you highlighted does not include an email address, Copy2Contact can get the sender of the email message from Outlook via the Add-in and offer it to you as an option.
Another feature provided by the Add-in is a special menu on each Outlook item window with some extra options, such as “Copy As Text”. See Reverse Copy2Contact for more info.
Outlook, however, is notoriously idiosyncratic when it comes to Add-ins, and it can seemingly randomly decide to disable an add-in and even report that the add-in has caused Outlook to crash. If the add-in is disabled by Outlook, the features it provides will all of a sudden not be available.
If you find that features provided by the Copy2Contact Add-in have stopped working, you can re-enable the add-in inside Outlook. You can also disable the add-in if Outlook insists that it is causing a problem.
Outlook 2000-2003: Open Outlook and go to “Tools”, then “Options”, then the “Other” tab, then “Advanced Options”, then “COM Addins”. Check (or uncheck) the “Copy2Contact add-in” option and then click OK. Close Outlook, close and re-open Copy2Contact.
Outlook 2007: Go to “Tools”, then “Trust Center” and click on the “Add-ins” section. Click on the “Copy2Contact add-in” and then click on the Go button towards the bottom. The “COM Add-ins” page will open and you can check (or uncheck) the “Copy2Contact add-in” there.
Outlook 2010-2016: Go to “File”, then “Options” and click on the “Add-ins” header on the left. At the bottom next to the word “Manage,” choose “COM Add-ins” and click the “Go” button. The “COM Add-ins” page will open and you can check (or uncheck) the “Copy2Contact add-in” there.
If Outlook keeps disabling the add-in, another option is to download and re-install Copy2Contact, which should restore the add-in as well. Download here.
