Temporarily Disable the Adobe Cloud Outlook Add-in

Turning off the Adobe Cloud add-in stops it from incorrectly processing and duplicating the viewed EML files into your inbox.

This behavior is a known conflict associated with how the Adobe Cloud add-in handles temporary file processing when an archived email is launched from SharePoint or other applications. Disabling the add-in serves as an immediate and reliable workaround.

1
Open Outlook Options

Launch Microsoft Outlook on your computer. Click on the 'File' tab in the top-left corner of the ribbon, and select 'Options' from the bottom of the left-hand menu.

2
Access COM Add-ins

In the Outlook Options window, click on 'Add-ins' in the left sidebar. At the bottom of the window, ensure that the 'Manage' drop-down menu is set to 'COM Add-ins', and click the 'Go...' button.

3
Disable the Add-in

Locate the 'Adobe Document Cloud for Microsoft Outlook' or similar Adobe add-in in the list. Uncheck the box next to it and click 'OK' to apply your changes.

Temporarily Disable the Adobe Cloud Outlook Add-in
Restoring Functionality: If you need to use Adobe Cloud features within Outlook later, you can return to the COM Add-ins menu to re-enable the add-in.

Frequently Asked Questions

Why do EML files keep saving directly to my Outlook inbox?

This problem often occurs due to conflicts with third-party COM add-ins, such as the Adobe Cloud add-in. The add-in misinterprets the action of opening an archived EML file from an external source and incorrectly creates a copy in the active email inbox.

How can I view EML files without adding them to my Outlook account?

You can temporarily disable the conflicting add-in through Outlook's COM Add-ins menu. Alternatively, you can use a dedicated text editor or a standalone mail viewer application to open the EML files instead of double-clicking them to open in Outlook.

Will disabling the Adobe Cloud add-in delete my existing emails or files?

No. Disabling the COM add-in in Outlook only stops the Adobe integration from running inside your email client. It will not delete your emails, attachments, PDFs, or any files stored in the Adobe Cloud.
