Internal Microsoft OneDrive For Business Sync Error - Manual Refresh of Folder Required

Hi @Alen.Alempijevic,

Can you clarify what you mean by this? Do you mean that when you perform a refresh, the file you are downloading still errors, instead of it being able to proceed? Or, are you seeing an error when you try to refresh?

I took a look at the diagnostics. OD4B is returning a 503 response, which indicates that the service is unavailable. They could also be using this as a throttling response.

odrive will automatically request a new token when required. I can see that there are operations that are succeeding, but OneDrive is returning a lot of 503s. Uploads will automatically retry and look to be going through after several retries.

I generally see a 429 response for throttling, rather than a 503, which leads me to believe this throttling may pertain to your tenant (organization), specifically. I am going to request s change for this integration to treat these 503’s a bit differently. It won’t stop them from happening, but will mandate a larger pause before making another request to OneDrive.

When did this issue start happening? I am wondering if there may be some heavy usage going on for your tenant that is resulting in a tighter restriction of API calls.
