how to implement OAuth2.0 in Jira cloud with microsoft office 365

[Tejaswini Donga]

We are migrating out Jira Data Center instance to Jira Cloud instance and want to know if Oauth 2.0 is possible in Jira Cloud and if so how do we setup Oauth 2.0 for Outgoing mail and integrate with Microsoft office 365 in Jira Cloud

Hi @Tejaswini Donga 

No this can't be done, as on Cloud outgoing mail can only be disabled or enabled.

See, https://support.atlassian.com/jira/kb/configure-outgoing-mail-in-jira-cloud/ 

You could look at a 3rd party app like Email This Issue

@Ugnius Aušra I hope you didn't use Ai to provide this anwer :), as the link you provideed this is for Data Center only.

@Marc -Devoteam-  I actually used search engine, to find documentation and didn't noticed on the right, that is for data center. 

My bad :(

Hello @Tejaswini Donga 

Yes, OAuth 2.0 is supported in Jira Cloud for both incoming and outgoing mail with Microsoft 

For Outgoing Mail (SMTP):

1. Go to Settings → System → Mail → Outgoing Mail
2. Click Configure new SMTP mail server
3. Under Service Provider, select Microsoftsupport.atlassian.com
4. Enter these settings:
   • Host: smtp.office365.comdocs.meta-inf.hu
   • Port: 587
   • Protocol: SMTP with OAuth 2.0
5. Click Authorize and sign in with your Microsoft 365 account
6. Grant the required permissions

For Incoming Mail:

1. Go to Settings → System → Incoming Mail
2. Click Add Mail Server
3. Select Microsoft as the service provider
4. Click Authorize and authenticate with Microsoft 365support.atlassian.com

Important Notes:

• Make sure your Microsoft 365 admin has enabled the required permissions for OAuth apps
• The email account you authorize must have proper mailbox access
• Basic authentication is deprecated by Microsoft, so OAuth 2.0 is now the recommended approachdipolimene.medium.com
