Perform a Clean Reinstallation of Adobe Acrobat
Use the official Adobe Cleaner Tool to completely remove existing corrupted application files and install a fresh copy of Acrobat.
Often, standard uninstallation leaves behind registry keys and corrupted files that continue to cause plug-in conflicts in Outlook. Using the dedicated cleaner tool ensures a completely clean slate before reinstalling.
Download the official Adobe Acrobat Cleaner Tool from the Adobe Developer site. Run the executable file and follow the on-screen prompts to completely remove the application.
Once the cleaner tool finishes, reboot your machine to ensure all cached files and background processes related to Acrobat are fully terminated and cleared.
Visit the official Adobe Acrobat DC downloads page to download the latest installer. Run the setup file to install a fresh, updated version of the software on your system.

Manually Reinstall the Send and Track Plug-in
If reinstalling the main Acrobat software does not resolve the issue, manually reinstalling just the Outlook plug-in can fix specific integration errors.
