BizTalk 2020 Office365 Email Send Port - Errors but emails sent every 5 minutes

Hi All

 

Bit of a stuck position and fairly new to Biztalk but been thrown in the deep end as our current support is in limbo,.

 

I'm trying to move our current SMTP send connectors to 365. 


Everything is configured as i think it should and an email is sent with the contents of the test xml file in the body instead of an attachment but Biztalk Errors every 5m with the following: 

 

The adapter failed to transmit message going to send port "Paul Test Outgoing 365" with URL "O365Mail://biztalk@domain.com". It will be retransmitted after the retry interval specified for this Send Port. Details:"An unexpected failure occurred when processing a message. The text associated with the exception is "Object reference not set to an instance of an object.
". ".

 

The Receive port is configured to monitor a folder for XML files and the Receive pipeline is set to PassThruReceive

 

The email is received fine 4 times every 5minutes until Biztalk suspends it. 

 

Anyone able to help?

 

Thanks in advance

    This issue should be fixed in latest BizTalk 2020 CU3. Until you have installed CU3, to avoid duplicate emails in earlier version, change retry to 0. Then the email should be sent once and then get suspended, which you can delete.
