Working with Mail365 shared Mailbox IMAP connection fails

[MichaelMcManus]

Attempting to connect to a Office365 shared account. Everything seems to be set up correctly. Connection works find for a normal username email account on 365.

Username for the shared account is entered as [email protected]\sharedaccountname which seems to be expected elsewhere with 360works and other places for using shared boxes..

The odd thing, if you change the connection to EmailConnectPOP from EmailConnectIMAP the connection for the shared account works fine and fetches mail.

Any ideas to make the IMAP side work?

Are you getting any errors when you try to connect to an IMAP server this way? If so, what is the error? 

[MichaelMcManus]

The plugin returns "error". The dialog return "Authenticate Error"

The log shows:

Oct 03, 2018 3:10:57 PM com.prosc.fmkit.Plugin setLastError
SEVERE: PluginFunction PluginFunction{name='EmailConnectIMAP', minArgs=3, maxArgs=-1} got an error with converted args [outlook.office365.com, [email protected]\sharedaccountname, XXXXXXXX, [tls=1, ssl=1]]

Guess I should also mention that this is done as a calculation.

Thanks

Can you successfully connect if you remove the "/sharedaccountname" ? 

I am not quite sure why this would work with the POP protocol vs the IMAP protocol. Might be a server side configuration issue.

 

As an aside, you don't need to set both TLS and SSL equal to one. The server should require one or the other.

[MichaelMcManus]

Thanks for that tls/ssl. Will change it.

It does work fine without "/sharedaccountname"

Excellent. I am assuming this is what Office 365 refers to as a shared mailbox? If so, are you able to read in the expected messages now?

[OlgerDiekstra]

You can't login to a shared office 365 mailbox. It doesn't have a license. You can only login to mailboxes that have a license. Shared mailboxes can be accessed by user accounts (mailboxes) that do have a license installed.
