Hi Kashish,

Good day.

Thank you for connecting with us in Microsoft community.

According to your mentioned error message "Remote server returned '550 5.7.705 Access denied, tenant has exceeded threshold",

I have found one official document NDR error codes 550 5.7.703, 550 5.7.705, 550 5.7.708, and 550 5.7.750 - Exchange | Microsoft Learn

If you are an End user, you will have to contact Office 365 global admin person in your organization to double check and perform certain necessary steps from their side.

==================================================================================================

If your scenario is different than above provided official document information, I would like to share more specific direction information with you, your current scenario should be diagnosed by Microsoft's frontline support team by colleting some advanced logs information. Frontline technical support engineer can also involve specific support team for further analysis some particular situation if it is required.

For example: if something wrong between email account and server in your Office 365 Business tenant or some other reason etc.., this kind of information need diagnose by technical support team from their backend resources and permission.

Since we forum moderators have limited permissions and access resources, due to this reason and for data privacy of users, we are unable to collect certain kind of logs information in the public forum which contain sensitive information.

After diagnosing the scenario, our technical support team can provide possible information from their end.

For the above provided standard process information, in your organization, Office 365 global admin person may need to contact Office 365 support team on backend  via an open service request so they can diagnose this specific scenario through some more technical resources,

For this standard process, here's the official document for the global admin reference: Get support - Microsoft 365 admin | Microsoft Learn (Online Option).

End users need to contact Office 365 global admin person in their organization to do some standard process and to connect with frontline technical support team.

Important note: If any organization's Office 365 Business/Business/Education subscription is from a syndicated partner or reseller, and if the global admin can't open the service request on their end, they may need to contact the reseller's support provider so they can help the global admin to open the service request on their end. after the Office 365 support team will involve in the created service request.

Your cooperation precious time is highly appreciated.

Sincerely

Vaidya Darpan
