There are two options for Outlook users: a downloadable client and an online application (OWA). Both provide essentially the same functionality, although some prefer the Web application since it does not occupy a lot of space on your computer.

Simple setup for searching, downloading, extracting and saving emails with attachments. Works with most email providers out of the box and does not require installing any other email clients.

The Web App (OWA) and the downloadable client are probably familiar to Microsoft Outlook users.

However, some users have reported difficulty downloading email attachments when using the web version, especially in Google Chrome. In addition, users seem to have problems downloading XML files when using the web app.

Attachments Not Opening In Outlook

It is possible that your computer cannot recognize an attachment in outlook because it is in a format that it cannot recognize. If you have not installed an app such as Adobe Photoshop, then you cannot open an image in .psd format. For example, your system may not have the software necessary to open an image in this format.

 

Why does Outlook Web App stop downloading attachments?

Why does Outlook Web App stop downloading attachments?

Browser compatibility: If you try to download attachments using a browser that is not supported by Outlook WebApp, you may encounter the current error.

Low bandwidth: If you are accessing Outlook WebApp over a network connection with low bandwidth, this may be the cause of the current error.

Inconsistent cache/cookie/user data: Older cache/user data may affect Outlook WebApp and cause this error.

Restrictions by security programs: Security programs such as anti-virus programs and firewalls tend to restrict network resources that they consider malicious. If these applications have identified the Outlook web application as malicious due to an error, the restrictions created by these applications can cause the Outlook web application to run the current error.

Attachment Not Opening In Outlook

A cached page or an issue with memory can sometimes prevent the attachments from loading. The first thing you should do is refresh the page to see if it works. Usually, just a simple refresh will resolve the issue. If it works, great, but if it doesn’t, you will need to try another option.

ISP Network Restrictions: ISPs have security and control methods and restrict certain network resources, and these ISP-imposed restrictions can exacerbate the current problem.

Can’t Open Attachments In Outlook

You can force Outlook to redownload attachments if you close and reopen the program. Depending on your version of Outlook, this may work.

Blocked Attachment Extensions: By default, Outlook Web App blocks certain types of file extensions as attachments. If you try to download such a file as an attachment, Outlook Web App will not allow the download.

It may be due to a file extension or format issue, your device not being compatible with the file or your antivirus blocking the attachment. You can use the following methods to troubleshoot the error if attachments cannot be downloaded or previewed on Microsoft Outlook web email. It can also be due to a corrupted file.

Suspicious sender: Outlook Web App uses sender filtering to identify rogue and malicious senders. If your sender is flagged as suspicious by Outlook Web App, this may be the cause of the detected error.

Incompatible browser add-ons: Some add-ons are incompatible with Outlook Web App, in particular, AdBlock has been known to interfere with Outlook Web App, causing the current error.

New UI: Microsoft often publishes a new UI to add functionality and improve the usability of Outlook Web App, but sometimes the new UI can cause the current problem due to a coding error.

In some instances, you may be able to download attachments from your emails after changing your web browser.

Try downloading attachments in zip format

The problem may be resolved by downloading the attachments as a zip file and then selecting the Download All option beneath each attachment.
