Post Attachment to SAP B1 Service Layer - python

In a Python application, I want to send files to "remote SAP B1 service layer". I have tried many ways to send an attachment to this remote service layer, using their b1s/v2/Attachments2 endpoint, but I continuously receive an error.
I can retrieve an attachment with GET with the same endpoint, but POST an attachment I can't.

Registering in Sharepoint through AppRegNew.aspx

I have a python script which will access the SharePoint. For this I am trying to generate a client Id and client Secret.
So there are five values:
Client Id
Client Secret
Title
App Domain
Redirect URI
I am not sure what I have to fill for the "App Domain" and "Redirect URI" values.
Can anyone help what these are supposed to mean in terms for my script?

Python O365 Outlook Connection Issues

I am trying to write a script in Python to grab new emails from a specific folder and save the attachments to a shared drive to upload to a database. Power Automate would work, but the file size limit to save the attachment is a meager 20 MB. I am able to authenticate the token, but am getting the following error when trying to grab the emails:
Unauthorized for url.
The token contains no permissions, or permissions can not be understood.
I have included the code I am using to connect to Microsoft Graph.
(credentials and tenant_id are correct in my code, took them out for obvious reasons
from O365 import Account, MSOffice365Protocol, MSGraphProtocol
credentials = ('xxxxxx', 'xxxxxx')
protocol = MSGraphProtocol(default_resource='reporting.triometric#xxxx.com')
scopes_graph = protocol.get_scopes_for('message_all_shared')
scopes = ['https://graph.microsoft.com/.default']
account = Account(credentials, auth_flow_type='credentials', tenant_id="**", scopes=scopes,)
if account.authenticate():
print('Authenticated')
mailbox = account.mailbox(resource='reporting.triometric#xxxx.com')
inbox = mailbox.inbox_folder()
for message in inbox.get_messages():
print(message)
I have already configured the permissions through Azure to include all the necessary 'mail' delegations.
The rest of my script works perfectly fine for uploading files to the database. Currently, the attachments must be manually saved on a shared drive multiple times per day, then the script is run to upload. Are there any steps I am missing? Any insights would be greatly appreciated!
Here are the permissions:

auth_flow_type='credentials' means you are using client credentials flow.
In this case you should add Application permissions rather than Delegated permissions.
Don't forget to click on "Grant admin consent for {your tenant}".
UPDATE:
If you set auth_flow_type to 'Authorization', it will use auth code flow which requires the delegated permission.

Sending email using python script from an Azure server

Using a python script, I am trying to send an email.
The mail part of the script looks like -
import smtplib
sender = 'abc.xyz#company.com'
receiver = 'abc.xyz#company.com'
message = """From: From Person <abc.xyz#company.com>
To: To Person <abc.xyz#company.com>
Subject: Inbound Folder Check - Alert
Unchanged even after an hour, please check
"""
smtpObj = smtplib.SMTP('smtp.office365.com',587)
smtpObj.starttls()
smtpObj.login('def#company.onmicrosoft.com','Password')
smtpObj.sendmail(sender, receiver, message)
The error that I am getting is -
raise SMTPDataError(code, resp) smtplib.SMTPDataError: (554, b'5.2.0

Only help I got on the internet was from the page - https://support.microsoft.com/en-us/help/3132755/554-5-2-0-storedrv-deliver-exception-objectnotfoundexception-mapiexcep
And it seems to say clutter is enabled but the folder is not present in the mailbox and suggests to turn off the clutter option which didn’t help.
PS - This works from my local machine within my company network but it is something to do with running it from Azure server.

First of all, please follow the offical document How to set up a multifunction device or application to send email using Office 365 to make sure whether set up correctly.
Secondly, if you were using Azure VM to send mail via SMTP, you can refer to this document Understand outbound SMTP problems in Azure VMs to try to fix your issue.
Meanwhile, for coding, there are some resources that may helps.
Python: Send Email via Office 365
Send email on App Service using Office 365 (O365) in PHP
Sending email from an Azure App Service using an O365 SMTP server in C#
Or using some packages directly like python-o365: GitHub and PyPI.
Finally, there is a service named SendGrid which be used for email service. You can use it to send mail in your scenario on Azure, please refer to the offical tutorial to know How to Send Email Using SendGrid with Azure (C#). For Python, you can code via its REST API or sendgrid python library.

Capturing email reply messages in Python

I have a web application in Python that allows someone to post a message. When this occurs, my application will automatically dispatch an email to the other user, who is following the "conversation/post". The user receive the email and replies with a message such as "Ok".
I want capture this reply message to a post in my application. I see this in applications such as Assana. How I can do this? Does there exists a service or API I can use?

Any email sent from the user will go to the domain mail server. If you want to receive it in a POST request, you'll have to write a separate application that retrieves email messages from the mail server and then sends the ones you want in a HTTP request to your web server. You'll then have to run your application as a daemon/service, and have it periodically poll the server for new messages (or use IMAP IDLE)
You may want to use imaplib to retrieve the emails.
Developing a complete two-way bridge between a web page and email with conversation tracking will likely require knowledge about MTA and LDA administration

Sending file via email to MMS for AT&T

One can send messages to an AT&T customer via [10-digit-cell-numer]#txt.att.net from their email client. I tried to send a file to my iPhone using this method (specifically an audio file) to no avail. The message came through but the file attachment was not present.

It seems you can send MMS messages to #mms.att.net
That was easy.
