I'm using the Google Apps Provisioning API to 1) create new users in our domain and 2), immediately after creation, move them into a sub OU which has the Mail service enabled. I would also like to use the Mail Settings API to 3) set a default SendAs for the new users at the same time. However, I don't seem to be able to set the SendAs until a small amount of time has passed. I get an InvalidValue(1801) ErrorCode. If I make the same call to the Mail Settings API a little later, it works fine. So, I'm guessing the problem is when the Mail Settings API call is made, the user hasn't been registered as being in the OU with the Mail service enabled yet.
Is there a way for me to set the SendAs immediately after the user creation and move? As a workaround, I can put a short delay in my code before the setting of the SendAs, but I'd prefer not to have to do this and I'm not sure what amount of delay would consistently be sufficient.
Thanks for any help you may be able to provide.
