Is there a throttle limit when using a DELETE request in GRAPH API?

Hi guys
 
I created a custom connector that I am using in a collection and different flows in power automate. The main target is to have a one-way sync between a file and contacts for different users in Outlook.
 
The custom connector, connection and authorization is working as it supposed to be, since I can do actions.
 
The only issue I'm currently facing is that certain DELETE request when using Graph API are giving me 403's and once every while a success (203? or blank page) 
 
The requests that are giving me these problems are:
 
So in short: I want to delete certain folders and childfolders in Outlook. In certain instances, it is working, but most of the time I get 403 errors while the flow is unchanged or when testing in the custom connector.
 
Is there a throttle limit when using a DELETE request in GRAPH API with contactFolders & childFolders
Did somebody experienced this issue also and what is the throttle limit (2 per 5 hours, 10 per day, ...) for these requests?
 
Thank you for your time.

    A 403 is basically “you’re not allowed to do that”.
    The call is fine, but the folder you’re trying to delete is blocked — and in your case I think the issue is that some of those folders are under a retention policy or temporarily locked because something is using them, not throttling.
    A 429 is “slow down, too many requests at once”.
    That one only shows up when you’re actually hitting Graph limits.
    So in short:
    403 = permissions/restriction on the folder
    429 = too many requests, try again later

    Adding to @SebS response,
     
    I am not sure about throttling limits, but I know it is not very less like 2 per day or 10 per week.
     
     
    I think the error is because of trying to access other users outlook and doing stuff on behalf of them.(Note this will work with your own outlook folders and sub folders, but won't work on other users outlook items)
     
    Which I think can result in 403 (Forbidden) unless you have a service principal or your own account with delegation permissions to access other user accounts outlook.

    Hi @JS-26111451-0 , 

    You’re not hitting a special “DELETE limit” in Graph throttling applies to all request types the same way. The 403s you’re seeing usually mean either the app doesn’t have the right permissions (Contacts.ReadWrite) or you’re trying to delete a folder that Outlook won’t allow (like default system folders). If you’re deleting a lot at once, Graph may throttle, but you’ll see a 429 Too Many Requests error in that case, not 403.

     In short: check permissions and make sure the folders are actually deletable. Add retry logic if you’re doing bulk deletes.
