We have given valid credentials and other parameters but still getting this issue. Can anyone help me on this?

Hi @Naveen B,


Hope you’re well. I compared your configuration with the one used by one of our customers, who has been using inbound mail processing with Office 365 for many years. Your configuration is correct but Office 365 is denying IMAP access.

There are two possible problems:

  1. IMAP access has been disabled for this account. I’m not an expert on Office 365 but can’t see a way to configure this from the admin center -- looks like it has to be done through PowerShell: Set-CASMailboxPlan
  2. Two-step authentication is enabled. You will need to create an app-specific password by following the instructions here: Manage app passwords for two-step verification

Hi @Gabriel Michaud  Hope you are doing well :)

Yeah, I’m good, and thank you :)  Thanks a lot for providing the possible options. I will look into it and keep you posted on the update.


Were you able to fix this problem? I am getting it and cannot seem to fix it even following the above instructions


To enable IMAP in O365 refer to this Microsoft doc.


I think you will need to use power shell to do this.  The app passwords can be problematic to use sometimes.  If you use an extremely strong password for this account, you can disable MFA for that ne account.

Hi @Naveen B,

Are you able to share if you managed to resolve the email setup error? I had the same error now and trying to figure out what went wrong. The email account to be used by Acumatica has been disabled for MFA and IMAP enabled.

Thank you in advance
