User impact: Users may be intermittently unable to download attachments or view embedded images in Outlook on the web.

More info: Users may see the following error message when an attachment fails to download: “Error downloading the file content.” Downloading attachments and embedded image viewing may succeed after signing out and then back into Outlook on the web. If available, users can download attachments and view embedded images consistently through the Outlook desktop client. We’re validating whether this problem also intermittently impacts Outlook mobile.

Current status: Development of the fix continues and once complete, we’ll deploy it to our internal testing environment and validate that it resolves this issue without further complications.

Scope of impact: Users attempting to download attachments and viewing embedded images in Outlook on the web may be intermittently impacted.

Root cause: A recent update, intended to improve the reliability of Outlook on the web, contains a code configuration issue that’s causing long running sessions, preventing attachment downloads and embedded image viewing.
