When I try and send certain Adobe XD file through Outlook it reports possible jar-related malware. I have done extensive tests to try and narrow down the issue but have come to an impasse and need help from Adobe.
When I try and paste the offending document into this community board it results in: "The attachment's 210223 test6.xd content type (application/octet-stream) does not match its file extension and has been removed." Therefore @Adobe, please reach out to me for a sample file that shows this issue.
1. When sending the outlook file, the message from Outlook reads:
Create a new file → save to desktop → Send through outlook → gets flagged
i.e. No objects were created in a file; it was saved completely blank
An Adobe XD file from 5/2020 → BAD
An Adobe XD file fom 1/2021 → GOOD
An Adobe XD file from 2/2021 → BAD
e.g. Sent a PPT, PDF, SVG attachments → works ok
- A colleague tried sending me back the same Adobe XD file → also flags as malware for him
- A colleague sent me a fresh Adobe XD file from his system → It came through successfully
A full Scan discovers no threats:
- Uninstalled and reinstalled Adobe XD using Adobe Creative Cloud app. Created new file and tried to send → also flags as malware
- Created fresh Adobe Photoshop document. Tried to send → Sent successfully through Outlook
A colleague sent me an existing file from Adobe XD for Windows v.184.108.40.206. → Sent successfully through Outlook
Saving a good Adobe XD file to my desktop and sending it works ok.
I updated to this version and it continued to flag the files as having malware
- A colleague using Windows on Outlook got the same malware handling when sending one of the offending Adobe XD documents
I used Mac version 220.127.116.11 and updated to v37. Both saved new, fresh files with the issue.
I created a fresh file with v37 and tried sending through Outlook and it again complained about malware.
I took a working file and saved it without changes and it was OK. I added some new data from a problematic file and it failed.
Took a errant file with my Mac version. Opened in A colleague’s Windows version, modified and saved it and sent it via Outlook / Windows
Outlook again flagged it as having malware
Opening it on Mac also prompted for an update to Adobe XD on the Mac that it had said was already up-to-date
- Outlook still called out malware in the file
- these could be sent
- these were also flagged by Outlook with the same message
- Files with objects copied from an offending Adobe XD document themselves become “infected”

We understand how frustrating it could be for you. Would you mind trying to compress the file and then try to send it? Outlook recognizes only certain file types and blocks the rest. For info on adding more file types to the approved list in Outlook, you can refer the user to this article: https://blogs.perficient.com/2016/06/03/office-365-have-you-enabled-common-attachment-blocking/
