Want to pre populate to, cc, subject, body by passing values to query parameters of outlook on the web deep link

Question

In our react application we are integrating outlook on the web email creation. For that we are using
https://outlook.office.com/?path=/mail/action/compose&to=test1@example.com,test2@example.com?cc=test3@example.com&subject=subject&body=body&&online=1 url to generate the email.

Right now the url is getting converted to https://outlook.office.com/mail/deeplink/compose?to=test1@example.com,test2@example.com%3Fcc%3Dtest3@example.com&subject=subject&body=body&online=1

All the fields are populating correctly.

But one issue we are facing when session is getting expire. After session expire, if we are generating email then cc, subject, body fields are not pre-populating.

I tried with replacing ? before cc with & but that is giving two issues.

1. cc field is not populating for any of the email
2. After session expire we are getting error

If some body can suggest any other ways to over come these issues that will be helpful.

Hello Bryll,

thanks for you reply.

So regarding your question.

After session expire, if we are generating email then cc, subject, body fields are not pre-populating for the first time. If we are generating after first try, everything working perfectly.

This issue is not limited to any particular account or device. It's happening for all.

I tried to replace the url itself. When I am using https://outlook.office.com/mail/deeplink/compose?to=test1@example.com,test2@example.com?cc=test3@example.com&subject=email%20subject&body=email%20body&&online=1

I am able to get ride of two issue

1. cc field is not populating for any of the email
2. After session expire we are getting error

But again if u will observe the screenshot in subject and body spaces are getting replaced with + sign.

This issue is happening when session is getting expire or when we will manually sign out and generate mail using the above url for the first time only.

Hi Sushil, this is Bryll

Thank you for taking the time to write us in the Microsoft Community.

I would love to give some troubleshooting steps to fix your concern. However, we may first have to wait for the answers to below questions to ensure that we understand your concern correctly and that we can provide the necessary guidance.

Can we verify if the issue is specific to a single Outlook.com/Hotmail.com email account? Additionally, is the problem occurring when using an alternative web browser or on another device?

How are you

Lastly, can you share a screenshot of the problem?

Best regards,

Bryll
