Exchange: ErrorNamespace

Problem

With an Exchange account, Authentication fails with the message:

ErrorNamespace (IMAP)

I don’t find any way to configure manually the authentication infos. Probably the problem is due to the fact that the email and the server domains are different (name.surname@domain.com vs mail.domain.com).

Additional Context

With other email clients I always had to manually edit the domain to from domain.com to mail.domain.com, and I think this is the same case. I wonder why mailspring does not yet have a simple tab for manually editing and reviewing the default configuration, this would be a very useful feature.

Some more details:

I am having the same issue in 1.2.2-96fb3a99

This is my log output:

I believe I need to change to AUTH=LOGIN but I’m not sure how to set this.

I just ran into this in 1.8.0 while attempting to connect to an O365 account. My browser loads the intended OAuth URL and I can complete that process, yielding the “You’re All Set!” success splash page at Mailspring

However the actual Mailspring App “Add Account” modal just sits there, then eventually shows the ErrorNamespace (IMAP) error.

I have the same problem with O365 Authentication. It seems that the Microsoft 365 accepts the login but then the Mailspring shows the error of ErrorNamespace.

My settings:
SO: Ubuntu 20.04
Mailspring version: 1.8.0 .deb
Account: Microsoft 365 Corporate

Same error @BinaryPaean and @jrmejiaa reported here. Version 1.7 used to work like a charm. It seems the problem is “User is authenticated but not connected”. Any hint here?

BTW, getting the same error when trying to connect to two different corporate accounts.

Hi,

I managed to work around this by downgrading to 1.7.8, setting up the account again, and then updating to the current newest (1.8.0). I tried this both on windows and ubuntu.

My specific issue was that I changed my office365 password, and got ErrorNamespace when trying to re-authenticate.

Thanks in general to the mailspring developers, much appreciated for a very useful piece of software.

This also works for me, but this is not a solution. With this new system of issues in this page I don’t know if they are working on that.

I hope that they fix this issue.

@jrmejiaa We do update when we start work on a task and/or manage to resolve it. This system is designed to make it easier for people to know what’s going on. Silence means we haven’t been able to work on it yet. (Development time is limited; PRs and diagnostic work always welcome.)

Thanks for the update @CodeMouse92. I am not sure how I can be useful because I don’t know much about the software that you use to develop the app. But if I can do test to help, I would love to do it.

Thanks for your time.

Same issue. And I don’t know any other solution than using another app. I will wait for some time in two apps, and hope it will be fixed. Cause your app is awesome!

Same issue as above, tried a fresh install several times and deleted the folders in AppData no luck. I can connect successfully in other apps including via IMAP on my cell phone via multiple apps. Only Mailspring give an issue.

Hi @wpbryant and @NickRimmer. This problem is a issue from the new versions of Mailspring. I know it is not a solution for the problem but until this could be solved, I stay in the version v1.7.8 of this project. If you want to test, I think that it could work properly also in your cases.

Greetings.

Thanks, yeah I’m sorta new so I’m not sure how to find this older version of the software.

If you go into the releases in Github, you are going to find the executable for the different versions of the System. This should be the version that would work for you

Hmm interesting I still get the error on 1.7.8
