Cannot add a hotmail.com account (There is no mailbox associated with this account)

Description:
On attempting to add one of my hotmail (outlook.live.com) accounts to Mailspring I receive the error “There is no email mailbox associated with this account.” Trying again with the same email account reproduces the same result.
Other hotmail accounts work in Mailspring. For some reason this one does not.

Steps to reproduce the behavior:

  1. Click on add account in the burger menu.
  2. Add account.
  3. Sign in with a specific hotmail account in outlook.live.com (email address, password, authy code).
  4. Receive above error message in Mailspring.

Expected Behavior:
I expected Mailspring to add the account as it had for my other accounts.

Screenshots:

Setup:
Windows 11 pro. 23H2. 64bit.
Installed via exe installer.
Mailspring ver. 1.15.1-cb02bf10

For me, it’s ErrorNamespace (IMAP).

Linux, openSUSE Tumbleweed

Installed via rpm installer.

Mailspring ver. 1.16.0-5339a49f


Sorry about the report :folded_hands: Mailspring works fine with my Hotmail account. The reason it didn’t work was because I didn’t turn on the IMAP option in Outlook settings.

This option must be on to use the app.
