I had to use exchangelib, to modify the subject of some of my emails. The following is the line of code that I am using to modify the email subjects. I am using App details with the exchangelib package.
credentials = OAuth2Credentials(client_id="", client_secret="",
tenant_id="",
identity=Identity(primary_smtp_address=""))
config = Configuration(credentials=credentials, auth_type=OAUTH2,
service_endpoint='https://outlook.office365.com/EWS/exchange.asmx')
account = Account(
primary_smtp_address=mailbox_name,
config=config,
access_type=IMPERSONATION)
inbox = account.inbox
if inbox.all().exists():
for message in inbox.all().order_by('-datetime_received')[:10]:
message.subject = "Modified Subject"
# message.save()
message.save(update_fields=['subject'])
The update message operation is throwing the below error:
message.save(update_fields=['subject'])
