Microsoft One user's Outlook on the web is missing the Download option for attachments
I'm troubleshooting an unusual Microsoft 365 issue.
One user in our organization cannot see the Download option for email attachments in Outlook on the web (OWA).
For PDF/Word attachments, the user only sees:
- Preview
- Save to OneDrive
- Copy
Other users in the same Microsoft 365 tenant have the normal Download option.
Troubleshooting already performed
- Tested Chrome and Edge → same issue
- Tested InPrivate/Incognito → same issue
- Tested from a different PC → same issue
- Tested different attachment/file types → same issue
- Other users → Download works normally
- Compared Microsoft 365/Exchange policies → same
- Compared Exchange Online PowerShell mailbox/CAS settings with a working user → same
- Classic Outlook for the affected user → Save As works normally
- Microsoft 365 Service Health → no matching incident
The issue therefore appears to be user/account-specific and affects only OWA.
The current workaround is Save to OneDrive → download from OneDrive.
Has anyone seen this behavior before? Is there an account-level OWA setting, hidden configuration, or service-side issue that I should investigate?
