What you’re seeing
- The option to open an attachment is missing in new Outlook; only preview or download is offered.
- Attachments open in a built-in preview pane rather than in Word, Excel or the expected program.
- Clicking a contact does nothing, or the People view loads blank.
- The same mailbox works normally in classic Outlook on the same PC.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- New Outlook is built on web technology and handles attachments through previews and downloads, so it doesn't behave like classic Outlook's direct open.
- The file type association for the attachment points to an app that isn't installed or that new Outlook can't hand files to.
- Microsoft 365 policies restrict opening or downloading certain attachment types in Outlook on the web, and new Outlook inherits them.
- Contacts stored in a local data file or a non-Exchange account aren't supported the same way in new Outlook.
- The WebView2 runtime that new Outlook depends on is outdated or damaged.
Why it matters
Email attachments and contacts are central to most office work, so even small friction here slows invoices, contracts, quotes and customer follow-up. Staff develop workarounds such as downloading everything to their desktop, which scatters copies of sensitive documents across PCs and complicates data retention. As Microsoft steers more users toward new Outlook, unresolved issues like this can spread across the office and create pressure to delay or reverse the transition.

Frequently asked questions
Should we move everyone back to classic Outlook?
It can be a reasonable stopgap, but Microsoft is steadily shifting users to new Outlook. Understanding why it fails for you is a better long-term answer than relying on the classic version.
Are our attachments or contacts lost?
No. They are stored in your mailbox; the problem is how new Outlook presents them on this PC.
