i am using graph api call to get the user info of our organisation. it returns 401 error code. we are using microsoft.identity.client that uses msal library. can you please help me in understanding why is it returning 401 http response?

hello, grant_type=client_credentials doesn't work for exchange 2016 on premise, for exchange online works perfect but for on promise i got 401 error 401 unauthorized unknownerror. https://graph.microsoft.com/v1.0/users/xxxx@xxx.com/calendar could you please help to solve this issue?

ut if i get the new token 5 minutes or less before the first one expires, the new token will only work until the expiration of the first one and plus 5 minutes after it. if i understand correctly, the token is created with a scope for a separate application and this token is used for requests to the web api based on spring boot. this spring boot uses a token to get a list of user groups from the azure graph api and now, 5 minutes after the expiration, the api graph starts responding with a 401 error. interaction with graph api occurs without the participation of the frontend side. i thought i found the solution by adding “offline_access” permition in the graph settings so that a user without authorization can get a new token. it started working better, but sometimes i have the same problem randomly and i can't figure out why it's happening. and the worst thing is that when i get such a situation, nothing helps even a re-log until the new token expires. server error which i get:

hello, i've looked online for answers to this question, but it's been difficult to find a related question/answer. i've recently installed windows 10 pro and have updated to the "2004" version. i've also recently installed report builder version 15.0.19210.0. when i open report builder and try to connect to a remote report server, i get the following error message: "the request failed with http status 401: unauthorized." i have even tried adding my username/password credentials for the remote report server to the windows credential manager under the windows credentials section at the advice of someone from a nearby work organization. i've double-checked the internet address for the remote report server and my username/password credentials. still, i get the 401 unauthorized error from earlier when i try to connect to the remote report server. is there something more i need to do in order to connect to the remote report server?
