EWS Send Error

[TopCatz]

Hi There
I have set up Exchange 365 on Aquamail, with EWS connection.
All my folders show up and receiving email is great, however I am unable to send any email from Aquamail.
The error is listed as

errorirresovableconflict

Please can you advise how to send email using EWS with Exchange365
Thanks

Did you mean Office 365?

I have an Office 365 account and just tried sending a message -- worked fine...

So, with this in mind, would you please capture the issue in a debug log, with "raw session data" enabled?

Hi Kostya
Yes, Office 365 is what I am using.

I have captured a debug log and sent it to the email address in the FAQ section.

Thanks for your quick reply to help me
All the best,
TC

Thank you.

This is the actual error messagae returned by the server:

"The user account which was used to submit this request does not have the right to send mail on behalf of the specified sending account"

I found other cases of this error, even when using Outlook:

This appears to be same information, but more to the point:
