Send as Alias from Microsoft Outlook mobile app (iOS and Android)
The Outlook mobile app for iOS and Android shows only the primary SMTP address in the From field, so aliases seem unusable on mobile. The aliases are actually there, but they have to be enabled for the account in Outlook on the web first, and then the mobile app has to be reset to pick them up. In this guide you will learn how to send as an alias from the Microsoft Outlook mobile app.
Why aliases do not appear on mobile
The mobile app reads the send-as aliases from the mailbox settings on the server. If the alias was never enabled in the Addresses to send from list, the app has nothing to show in the From field.
Enable aliases in Outlook on the web
Turn on the aliases you want to send from in the Outlook on the web settings for the account.
Reset the account in the mobile app
The mobile app caches the account settings. A reset forces it to pull the alias list from the server without removing any of your app preferences.
Send from the alias
After the reset, the From field shows a dropdown so you can pick which address to send from.
Frequently asked questions
Why is my alias missing from the From field?
The alias has to be enabled in the Addresses to send from list in Outlook on the web, and the mobile app needs a reset afterwards.
Does resetting the account delete app settings?
No. The reset only syncs the account configuration from the server; your app preferences stay intact.
Does the alias work for replies as well?
The alias is available in the From dropdown when composing or replying to a message.
Do I need an Exchange admin for this?
The alias must exist on the mailbox. Enabling it for the app is something the user does in their own settings.
Will the alias show for recipients?
Yes, the alias address appears as the sender in the recipient’s mailbox.
