Fixing OAuth Authorization Errors

OAuth errors usually occur when: 1) You denied a required permission during authorization — reconnect and accept all required scopes. 2) Your organization's admin has restricted third-party app access — contact your IT administrator. 3) The OAuth token expired — go to Settings > Accounts > Reconnect to refresh. 4) Browser cookies or extensions are interfering — try in an incognito/private window. For Google Workspace accounts, your admin may need to approve Kamili Mail in the Google Admin Console.
