Microsoft Office 365 Outlook compatibility, oauth2 login

In the process of migrating all of my emails to ONLYOFFICE Version 12.6.0.1900, everything went perfectly except for one account where my client uses Microsoft Office 365 for everything. I cannot login to my outlook mail account since ONLYOFFICE Mail does not support the oauth2 authentication method, EWS (Exchange Web Services).

I do have a workaround, putting the Outlook Webmail link on the module choice page, but I would rather have the full integration I have come to love in ONLYOFFICE.

Hello @aharper
We are checking the situation. I will update this thread as soon as possible.

Hello @aharper
Could you please describe the situation with this one account (oauth2 authentication) as detailed as possible? Do you mean the scenario of authenticating on the Workspace portal using oauth2 credentials?

Trying to authenticate on a client’s Microsoft 365 corporate email account The automatic email account creation give an Account Connection Error. I cannot show the details because I get the error in the forum that new users may only post 2 URLs.

Going into advanced settings, Going to the advanced settings, there is no provision for application ID which will be required, though these IDs often work.

To be able to use OAuth2 with outlook.office365.com server an application ID, which identifies the application which requests access to user data, and a tenant ID, which basically identifies the organization, are required, though sometimes the owner of the Outlook account configures the server (service?) to not require the tenant ID.

Hello @aharper
Your forum level has been increased. Please clarify if you meant the Single Sign-on feature for portal authenticating. If it’s possible, please show us the entire scenario (you can record a videofile or make screenshots).
