Hello, recently the new Outlook app replaced the Mail and Calendar apps. It's nice, but I noticed that when I double click on a .eml file (that was usually opened with the Mail app) this happens: The Mail app launches, and instantly closes itself to redirect me to Outlook The Outlook app then launches, but does not open my .eml file. Instead, it lands on its "home page" like when I open the app with its launcher. I currently cannot open .eml files. If I try to change the default app to open this format, Outlook doesn't appear on the app list so I cannot chose it. I don't know where its launcher is on disk either, so I cannot select it manually. What should i do to fix this issue?

I found a work-around. If you attach the .eml file to a new email, you can open it there with New Outlook.

Hello, thank you for your answer. As i said on my post, If I try to change the default app to open .eml files with Outlook, Outlook is not present in the app list that appears so I cannot choose it. The thing is that i went back to old Mail a couple weeks ago, but today Outlook appeared again by itself and "took control" (some update maybe?) Anyway, .eml is a standard file type for emails, the Outlook app not being able to open it is a bit absurd.. Thank you!

If I use Mail as the "Open with", it will start to open the file with the Mail app, but as the switch is set to "new Outlook", it then switches into the new interface wich closes the file. I tried setting the "Open with" to use the "new Outlook" located here; C:\Program Files\WindowsApps\Microsoft.OutlookForWindows_1.2023.1018.300_x64__8wekyb3d8bbwe\olk.exe Windows added the "new Outlook" option to my "Open with" menu, but when it opens I get the following Popup; When I switch to the Classic Outlook for Windows, I am able to view the .EML files, my only fear is that when the Classic Outlook for Windows is depreciated and we are forced to use the New Outlook for Windows, we will lose this functionality. Emails are saved to our CRM, and if we need to view them they have to be downloaded to the users PC, so emailing them to yourself so you can read them several times a day as a workaround is an extra step and a very inefficient use of people's time. I do hope the development team is aware, and will remedy the situation prior to the depreciation of the Classic Outlook for Windows.

Hi AleB I'm AnnaThomas and I'd happily help you with your question. In this Forum, we are Microsoft consumers just like yourself. Sorry for the trouble this might have caused. You can try changing the default apps by file type from the settings Right-click on the start menu click on apps and features default apps Scroll down and choose default apps by file type, then choose Outlook(new) If you still cannot open the file type, you can switch back to Old mail. On Outlook click on the switch New Outlook. Outlook new is still been improved on and as such might not be able to open the file type in question I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.

The new Outlook app doesn't open .eml files

Hello, recently the new Outlook app replaced the Mail and Calendar apps. It's nice, but I noticed that when I double click on a .eml file (that was usually opened with the Mail app) this happens:

The Mail app launches, and instantly closes itself to redirect me to Outlook
The Outlook app then launches, but does not open my .eml file. Instead, it lands on its "home page" like when I open the app with its launcher.

I currently cannot open .eml files. If I try to change the default app to open this format, Outlook doesn't appear on the app list so I cannot chose it. I don't know where its launcher is on disk either, so I cannot select it manually.

What should i do to fix this issue?

It has been a while since this issue was reported and now changing the default app for viewing .eml files to Outlook (new) from the context menu is available. Please change your default app to Outlook new and then try double-clicking on your .eml files.

If I use Mail as the "Open with", it will start to open the file with the Mail app, but as the switch is set to "new Outlook", it then switches into the new interface wich closes the file.

I tried setting the "Open with" to use the "new Outlook" located here;

C:\Program Files\WindowsApps\Microsoft.OutlookForWindows_1.2023.1018.300_x64__8wekyb3d8bbwe\olk.exe

Windows added the "new Outlook" option to my "Open with" menu, but when it opens I get the following Popup;

When I switch to the Classic Outlook for Windows, I am able to view the .EML files, my only fear is that when the Classic Outlook for Windows is depreciated and we are forced to use the New Outlook for Windows, we will lose this functionality. Emails are saved to our CRM, and if we need to view them they have to be downloaded to the users PC, so emailing them to yourself so you can read them several times a day as a workaround is an extra step and a very inefficient use of people's time.
