AWS Simple Email Service not sending emails to outlook.com or live.in from ap-south-1 region

Question

I am unable to verify outlook.com or live.in mails with AWS SES. Not receiving the verification mail. The account is moved out of the sandbox and it is working when sending to other providers such as Gmail. The issue is present when using ap-south-1 region. If I select another region able to verify outlook.com mail. Kindly share your suggestions

There is an exception for region ap-south-1. You need to get out of the sandbox in a different region: ap-southeast-1 I found this exception here:

[https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-settings-email-phone-verification.html]()

SMS messages from Amazon Cognito user pools are routed through Amazon SNS in the same region unless noted in the following table.

| Amazon Cognito Region | Supported SNS regions |
| --- | --- |
| US East (Ohio) us-east-2 | us-east-1 |
| Asia Pacific (Mumbai) ap-south-1 | ap-southeast-1 |
| Asia Pacific (Seoul) ap-northeast-2 | ap-notheast-1 |
| Canada(Central) ca-central-1 | us-east-1 |
| Europe (Frankfurt) eu-central-1 | eu-west-1 |
| Europe (London) eu-west-2 | eu-west-1 |

Example: If your Cognito user pool is in us-east-1 region, you can update the Amazon SNS limit in us-east-1 region.

Example: If your Cognito user pool is in ap-south-1 region, you can update the Amazon SNS limit in ap-southeast-1 region.

Please check and confirm your SPF and DKIM settings. I faced similar issue with AWS SES with office365, once I fixed the DKIM it started working properly.
