Posted on by 65

Hi, 

I had created a code unit which was responsible to get the customer names and send in email i created that code unit to test the background job functionality for testing purpose and left it for some days with Ready status.

From today i am unable to send the email to my gmail account or outlook account from business central dynamics 365. 

Here is the screenshot of the error. I found this from the dashboard showing failed emails so i loaded the failed email and clicked on show error.

Is there any limitation in the sandbox or this issue is something else? i have tried to search this error but didn't get any information.

Any suggestions please how to fix this issue yesterday the system was sending the emails using the background job.

    Hi, I'm not sure if this has anything to do with your question, in BC21.2 Microsoft added the following new functionality.

    Business Central 2022 wave 2 (BC21) new features: Set Email Rate Limit per Minute (Easily comply with email-sending limits through email throttling)

    Hope this helps as well.

    Thanks.

    I agreed with Mohana Yadav check if your email quota is full in Gmail account.

    Thanks.

    Looks like due to daily limit quota.
