URGENT UPDATE: Microsoft has confirmed a significant bug affecting the new Outlook app, preventing users from opening Excel attachments with non-ASCII characters. This issue has prompted immediate concern from users who rely on this functionality for their daily tasks.
Reports indicate that since its launch, the new Outlook app has struggled to gain acceptance, with users expressing frustration over its performance and missing features compared to previous versions. Now, with the latest bug identified as issue EX1189359, users are facing yet another hurdle.
According to a service alert published by Microsoft, users attempting to open Excel files attached to emails in the new Outlook may encounter an error message stating, “Try opening the file again later.” The problem specifically impacts attachments that include non-ASCII characters, such as accented letters or non-Latin script.
To mitigate the disruption, Microsoft is advising users to either access Outlook via the web or download the attachments locally to open them in Excel. This workaround is crucial for anyone handling files with special characters in their names.
Microsoft is actively working on a fix and expects to roll out an update soon, though it is still conducting tests to ensure the issue is fully resolved. As users await a permanent solution, many are exploring alternatives to the new Outlook, with reports suggesting some have successfully transitioned to different email applications in 2025.
The urgency of this situation is palpable, as many professionals rely on seamless access to Excel files for critical tasks. With the holiday season approaching, the impact of this bug could disrupt workflows for countless users.
Stay tuned for further updates as Microsoft addresses this pressing issue. In the meantime, those affected should consider utilizing Outlook on the web or alternative applications to manage their email attachments effectively.
