Failure with office365 shared inbox

[Teemu Keinonen]

Hi, I'm trying to access shared inbox in Office365, unsuccessfully. Authentication is OK but mail is not shown. Below is IMAP log. Is this a known issue and is there a way around this?

Forgot to mention that shared inboxes are accessed with credentials like this:

sharedinbox@company.com/inbox.user@company.com

Any leads on this?

A quick search suggests that you've got the password wrong and the error from Exchange IMAP is misleading http://unix.stackexchange.com/questions/164823/user-is-authenticated-but-not-connected-after-changing-my-exchange-password

Hi,

That can't be the case, I can log in fine to my own account with the password. How do I specify to roundcube that I want to log in to the shared mail account that my main mail account has credentials to?

[JohnDoh]

Well ok. Like I said it was only a quick search. I have never tried to access Exchange mailboxes via IMAP. Are you sure what you are trying to do is supported by MS? I have see a few old posts in the MS community that say support for it was removed in Exchange 2013. I found another post that using a special username might do the trick.

Roundcube does not support using different usernames for different folders. I guess it might be possible to do using a plugin because plugins can manipulate the username but I'm not sure about just for specific folders.
