Hello Experts ,
I have configured a mailbox and got it tested successfully for both incoming and outgoing mails with server side synchronization.
I am able to send an auto reply from the same mailbox but when i try to send a mail manually from user activity timeline , the mail goes in pending state and shows error "This message has not yet been submitted for delivery. For more information, see help.".
I am not able to find the root cause of the issue.
anyone who can suggest some solutions for the same.
Hello,
Thanks for the update and glad to hear you were able to find the resolution. The reason users have a mailbox for '<username>' and other simply by 'username' is because the one with the <> enclosing the username is a queue user mailbox. These are disabled by default.
It may be necessary in some scenarios where you would configure a Dynamics 365 user as a queue but for most customers, the user mailbox record that is just the 'username' is the mailbox that will be used and is the mailbox record that is active by default.

Hello Lance,
I got the issue resolved.
The issue was related to different mailboxes with same email.
I found that the sandbox instance has two different mailboxes for same user by default.
one is '<username>' and other simply by 'username'.
Why there are two different mailboxes for single user by default?
Hello,
Thank you for providing the requested information. From everything you have described, the mailbox is configured and working successfully.
When you are performing your email test by creating a new email activity, who are you logged into Dynamics 365 as? Are you logged into the system as a different account and then setting the From field as the mailbox that is successfully Test & Enabled?
Hi Lance,
Hello,
What this is telling us is that the user's mailbox who we are attempting to send the email from is not being processed by Server-Side Sync for outgoing emails which is why it is not being picked up by Exchange.
So if we are sending auto reply email from a generic mailbox successfully, we need to start digging into the differences between the mailboxes.

Hi Lance
Thank you for your response.
There are no processes for email entity.
In Advance Find The 'no. of Delivery attempts' is 0 for all the pending send status mail messages.
I enabled auditing too for Email. Is just shows status as pending send and activity status as completed.
The auto reply is from generic mailbox but it is approved and tested successfully.
The Recipients email activity shows email as closed but the recipient does not find any email in its mail folder.
What can be the reasons behind 'no of Delivery attempts' to be 0?
Hello,
There are a couple of things you can look at if the emails are stuck in pending send.
The first is to check on whether there are any Workflows/Plugins that are triggered on the Pending Send action. This almost seems like the status of the email is being reset when the email is attempting to send.
You can check to see if there were any delivery attempts on the email by using an Advanced Find on "Messages" and adding the column "no. of Delivery Attempts". If the Status Reason is "Pending Send" and the Number of Delivery Attempts is 0, it means that the issue is within Dynamics 365 as we are not attempting to hand this email over to Exchange.
Do you have auditing enabled, this may help shed some light on any interaction that happens in Asynchronously after we click Send.
When you use the Auto Reply to send an email, are you sending this under the context of the user mailbox or is there a generic Auto Reply Mailbox that is used?
Do the recipients resolve to a record in Dynamics 365 or do they show as unresolved on the email activity in Dynamics 365?

Hi Clofy
Thank you for the response.
I tried all the steps from the link you provided but not able to resolve the problem.
I have already got my mailbox approved but then also not able to send outgoing mails from CRM.
