Title: Users may be intermittently unable to download attachments or view embedded images in some Outlook connection methods
User impact: Users may be intermittently unable to download attachments or view embedded images in some Outlook clients.
More info: This issue may impact those who are downloading attachments or viewing embedded images in either Outlook on the web or the Outlook mobile apps. 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 or the Outlook mobile app. If available, users can download attachments and view embedded images consistently through the Outlook desktop client.
Current status: We’re continuing to monitor the fix as it deploys to all affected environments, which is taking longer than initially anticipated. We’ll aim to provide a estimated timeline for the fix to finish deployment by our next scheduled update.
Scope of impact: Users attempting to download attachments and viewing embedded images in Outlook on the web or Outlook mobile apps may be intermittently impacted.

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