WorkMail - EWS - OauthAuthentication

[tamili2i]

Hi,
I am using ExchangeLib to fetch Mail from different mailboxes from WorkMail. I have enabled Impersonation Role to fetch mails. How to implement OAuth Authentication for the same?

I don't know how OAuth towards AWS WorkMail works. Generally speaking, the simplest OAuth solution in exchangelib is to fetch an access token via some means outside of exchangelib and then create a credentials instance like this: OAuth2Credentials(client_id=None, client_secret=None, access_token='blablabla').

How to manage OAuth2Credentials in exchange-lib?

[ecederstrand]

What do you mean by "manage"? The code I posted above shows how to create an OAuth2Credentials that you can use as the credentials object for your Account instance. I've seen reports that exchangelib works with AWS WorkMail, but be aware that WorkBail is a reverse-engineered version of the EWS protocol from Microsoft, so there may be some differences.

I am not sure how to get client_id and tenant id to create OAuth.

[ecederstrand]

I don't think you need them. In theory at least, the access token would be enough.

Okay Got it. Thanks for your explanation.
