Hi All,

 

We are using Intune for MDM and MAM for our iOS and Android devices. With Intune we push several applications including Outlook and Adobe Reader for Intune. When we add a signature to a PDF file on the mobile device and send it through the Outlook app, we can't open it on our Windows devices.

 

Adobe Reader states that file has been corrupted and cannot be repaired. When we try it through OWA, we receive the message that the file header doesn't start with %PDF. We are using Exchange Online as our email services.

 

We've tried the suggested solution in the following link (https://helpx.adobe.com/acrobat/kb/pdf-error-1015-11001-update.html) but that doesn't solve the issue.

 

Can anyone point me in the right direction? Thanks in advance.

 

Best regards,

Ruud Gijsbers

I'm not following why you think this is an MDM or MAM problem, can you add more details as you why you think it is an MDM  or MAM issue?

Hi Garth,

 

Thanks for your response. You already helped me with your question. To be honest, this question was placed in a hurry. The reason why i think/thought it has someting to do with MAM, is because this problem doesn't occur with the normal Adobe Reader app (With or without Intune enrollment). And the only other thing I could think of, would be that it has something to do with Application Protection Policies.

 

We have an application protection policy in place for Office applications and Adobe Reader for Intune with the following settings

I'm going to test if the problem also arises when the policy isn't in place. I'll post the outcome here. Thanks for now.

Eventually it wasn't MAM or MDM related. It looks like it had to do with something the end-user did wrong. After some testing, it worked for several test accounts.

 

Best regards,

Ruud Gijsbers
