ServiceNow for Microsoft 365でPortalが開けずエラーが表示されます原因と解決の機会を知りたい。
エラー：「ユーザー認証中にエラーが発生しました」
ーーーーーーーーーーーーーーーーーーーーーーーー
考えられる原因は、以下。
・Azure Portalのアプリにインストールした[SSO and Activity Notification]のAPIの要求の値[TeamsActivity.send]を削除。（権限が強いため一時的に削除）
・カスタムポータルの埋め込みを実施。ESCポータル⇒XXサービスポータルに変更
・sys_properties＞sn_now_teams.portal.suffix ＞suffix＞Value＞XXspに設定
　※空の場合は標準でESCポータルになる。

I can't open Portal in ServiceNow for Microsoft 365 and I get an error. I want to know the cause and the opportunity to resolve it.
Error: "An error occurred while authenticating user"
----
Possible causes are as follows:
- Deleted the API request value [TeamsActivity.send] installed in the Azure portal app. (Temporarily deleted due to strong permissions)
- Custom portals have been embedded. ESC Portal ⇒ Change to XX Service Portal
・Set to sys_properties>sn_now_teams.portal.suffix>suffix>Value>XXsp
*If it is empty, it will be the ESC portal as standard.

Hi @NatsukiO 

I’ve come across a couple of similar cases in the ServiceNow Community where the ServiceNow for Microsoft 365 (Teams) app showed the error “An error occurred while authenticating user”. These might be helpful references:

In this case, the issue was due to a mismatch between Azure AD UPN and the ServiceNow user email. Adjusting the OIDC claim mapping resolved the authentication problem.

Here, the error was also authentication-related. The resolution involved verifying that Azure AD attributes (UPN/email) were properly aligned with the ServiceNow user table.

If my response helped, please mark it as the accepted solution so others can benefit as well.
