Over the weekend we upgraded from 2022 R1 to 2023 R2.  Prior to this we were using IMAP to send emails through our Exchange server.  We haven’t had any issues with this method until after the upgrade.  Now we are getting an error “The remote certificate is invalid according to the validation procedure.”.  Our certificate is not invalid.  We have been told that Microsoft has deprecated Basic Authentication and they have, for Exchange Online.  However Modern Authentication just became available in CU13 in May of 2023 and we were using it sucessfully in Acumatica until the upgrade.

Has anyone else run into this issue and if so how did you fix it?  Thursday is ACH day and we will have over 200 remittance advices to send out.  We really don’t want to use the Exchange integration because we don’t want it that involved in our emails but we do need the ability to send out order confirmations, shipping confirmations, ACH notifications etc.

I don’t see a way to edit my post and the part above is a little unclear after reading it again.  We were not using Modern Authentication prior to the upgrade we were using IMAP with Basic Authentication and want to continue doing so for now.  We are currently on CU11 and Modern Authentication is not available to us yet.

We are self-hosted.  The Acumatica application & database servers are installed in-house in the same VMWare environment as our Exchange server.
