    @JmArreola is that error a data size limit error? what is the supported data size limit for an email attachment? This is a highly asked customer scenario and we have some customer trying to automate their data pipeline using this.

    Yes @JingChang, I mean the From, To and Subject filter, if you can just modify the flow to be the same as it failed yesterday.

    Hi @JmArreola sure thing! I will validate and let you know. just to make sure, you mean with From, To, and Subject filter all empty (default to accept all), it should work?  do you just want me to remove subject filters or remove all three?

    Re: Getting error 502 when saving email attachment

    Hi @JingChang the filters are not required. The flow should work with and without them. I already have the logs for the failures of your Flows and we will investigate the reason why they failed.

     

    Yesterday we had an issue related to this connector, i will see if your issue is related. In the meantime, just to double check, can you please modify the flow, remove the filters and test it again now?

    okay, @JmArreola, I forgot to tag you in previous conversations, Now with all From, To, Subject Filter specified, I had a successful save of email attachment to one drive.

     

    What is the right way to save all email attachments without specifying sender and subject filter?

     

    thanks

    Jing
