Title: Users may be intermittently unable to download attachments or view embedded images in Outlook on the web
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.” We’re validating whether this problem also intermittently impacts Outlook mobile.
As a potential workaround, downloading attachments and embedded image viewing may succeed after an affected user signs-out and then signs-in again to Outlook on the web, if appropriate.
Additionally, users can download attachments and view embedded images consistently through the Outlook desktop client, if available.
Current status: We’ve completed the internal validation process and started the fix deployment to the affected environment. We anticipate this will finish and remediate the impact by our next scheduled update on Thursday, April 11, 2024, at 9:00 PM UTC.
Scope of impact: Users attempting to download attachments and viewing embedded images in Outlook on the web may be intermittently impacted.
Start time: Friday, March 29, 2024, at 12:00 AM UTC
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.
