Hello,

i got a problem selecting the .pdf attachment in outlook. error code says that no preview can be showed, because the needed preview isn't installed.

Server 2012 R2 as Terminalserver, Outlook 2010, newest version of adobe reader XI.

I've already checked the following:

- outlook>options>trustcenter>trustcenter settings>attachment handling .. the box disable preview is clear .. furthermore outlook>options>trustcenter>trustcenter settings>attachment handling>attachment and documentpreview .. all boxes including pdf preview handler are filled.

- adobe reader XI>edit>presettings?>e-mail-account ... outlook is standart.

- Registryentry: "Change the AppID value to {534A1E02-D58F-44f0-B58B-36CBED287C7C}"

- also i repaired the adobe installation and i reinstalled it a few times.

- even checked the access-rights on the temp. directorys outlook uses for attachments and the users have full access.

i have no more clue what it can be..

so may you have the solution for me or at least some tips.

Thanks,

Nikolai

Hi Nikolai,

We may try to disable protected mode in Adobe Reader to see the result.

To modify when the Protected View is used, do the following:

1. Choose File > Preferences.

2. In the Categories list on the left, select Security (Enhanced).

3. In the Sandbox Protections area, select an option for Protected View:

• Off
• Files from potentially unsafe locations
• All files

Please let me know the result.
