Hello,
We encountered a similar question while validating Sales Order Agent during implementation.
Based on the information shared, I'd first verify that the Business Central environment meets the supported prerequisites before investigating permissions further. Sales Order Agent is available only for supported country/region versions, so using an unsupported localization can result in behavior that appears to be a permission issue even when the configuration is correct.
If the environment is supported, I'd then verify:
-The Sales Order Agent is correctly configured and enabled.
-The monitored mailbox is working correctly.
-The Agent User has access to the target company and the required permission sets.
-The environment meets the current Microsoft prerequisites for Sales Order Agent.
We documented these prerequisites and implementation guidance here:

I hope this helps.
