With the new MFA, I can no longer use IMAP to configure office 365 emails in Acumatica. Need assistance.

Hi @Martha Cepeda ，
As mentioned in this official article, with the deprecation of basic auth in Exchange Online, OAuth 2.0 auth is required to be implemented for applications to access IMAP, POP and SMTP AUTH protocols in Exchange Online. So, agree with Dillon that it'd be best to reach out to Acumatica for help on this. By the way, if Dillon's reply has been helpful, you can consider accepting his post as answer help increase visibility of this question for other users in this community.
Hello Martha,
You will need to speak to your IT Administrator (or if you are one) to exclude the account you are using from MFA to send e-mails.
If this is not possible, you may need to reach out to Acumatica to see if they have a solution for Modern Authentication.
It looks like Acumatica is already discussing this issue:
