Unable to add Shared Mailbox as custom email channel for project

[Shruti Sharma]

Hi,

I want to add a custom email account for my project. This account is an Exchange Shared Mailbox account without any password. When I click on Microsoft icon for adding the account it is redirecting me to Microsoft login page and shows the message - "Need admin approval". I then tried using Other icon which requires entering a password and the shared mailbox doesn't have a password.

Can someone please help me with this issue.

Thanks,

Shruti Sharma

There are a number of posts on unsuccessful attempts to use Shared Mailboxes. I have yet to see an example of this being successful.

Thanks Jack,

I also tried adding MS Office 365 service account and it doesn't work either.

I get the below error - 

Can you please tell me if you know what could be wrong here.

My understanding is that because "service accounts" (and certainly "shared mailboxes") are not people, they have different authentication and usage. 

Because of that, it's inappropriate to try to authenticate against them as if they were people and hence MS doesn't support it.

You can, of course, set up service accounts as a "dummy user" instead of a service account (and then configure them to look like a service account and behave in mostly the same way), I suspect that's your only option here.
