OAuth 2.0 Service mailbox - invalid client_id

David Hollegien 4 Nov 2021

Hello,

We just migrated to Office/Microsoft 365 and I wanted to use the new Modern auth functionality for connecting our service mailbox, but I get the following error when trying to setup OAuth:

When I log into the mailbox manually (outlook.office365.com), it works fine.

Hey Markus,
The situation of 2 duplicate serial number both uses OAuth - and get an error for doing so - is by design - for security reasons. Fixing the "lock" to that serial number will only be temp - if you again uses it on both installations running on the same serial number. IF you cant to use this feature on 2 tenants - you need 2 unique serial numbers. Reach out to support with the serial number you would like to "unlock" - for resolving the situation.

If you need help with a feature after the end of the pilot program, reach out to our support team - they will be able to help you out.
