Solution 1Recommended

Verify Account Sync and Re-enable the Acrobat Add-in

Ensuring both applications are logged into the same Adobe account and refreshing the add-in resolves most upload errors.

Upload failures often happen because Outlook and Adobe Acrobat are out of sync or the add-in has temporarily stalled. Re-authenticating your accounts and refreshing the add-in connection can quickly restore functionality.

1
Check Adobe Account Logins

Open Adobe Acrobat and verify you are signed in. Then open Outlook and ensure any connected Adobe services use the exact same account credentials.

2
Access Outlook Add-ins

In Outlook, navigate to File > Options > Add-ins.

3
Manage COM Add-ins

At the bottom of the window, ensure 'COM Add-ins' is selected in the Manage drop-down menu and click 'Go'.

4
Disable and Re-enable

Uncheck the Adobe Document Cloud or Acrobat add-in, click OK, and restart Outlook. Repeat the process to re-check and enable the add-in.

Frequently Asked Questions

Why did the Adobe Acrobat add-in suddenly disappear from Outlook?

Outlook automatically disables add-ins that cause it to load slowly or crash. You can re-enable it by going to File > Options > Add-ins, selecting 'Disabled Items' from the Manage drop-down, clicking Go, and re-enabling the Adobe add-in.

Can I upload attachments to Adobe Document Cloud without using the Outlook add-in?

Yes. You can manually save the email attachment to your local hard drive first, then log in to Adobe Document Cloud via your web browser or the Acrobat desktop app and upload the file directly.

What should I do if repairing Adobe Acrobat doesn't fix the upload error?

If repairing the installation doesn't work, uninstall Adobe Acrobat completely and reinstall the latest version from the official Adobe website. If the error continues, document the exact error message and contact Adobe Support for further assistance.
