Microsoft 365へのロックインを回避し、交渉力と自由度を維持するには

Published: 22 May 2023


多様な機能を備えたMicrosoft 365は、国内大企業で最も利用されているコラボレーション・スイート製品であるが、他基盤への移行が難しい、いわゆる「ロックイン」の状態に陥るユーザー企業が少なくない。本稿では、デジタル・ワークプレース戦略を推進するアプリケーション・リーダーがMicrosoft 365の継続利用以外の選択肢を知り、ベンダーに対する交渉力と製品選択の自由度を維持するための方法を提案する。

Included in Full Research



Microsoft 365のユーザー企業は、以下を主な要因として「ロックイン」の状況に陥る傾向がある。

  • Microsoft 365に含まれるアプリやサービス上に構築されたアプリケーションの移行に、多くの工数と期間を要する。

  • Microsoft 365の現実的な代替案、つまり現在利用している機能を提供できる代替製品 (群) のめど付いていない。

  • 代替製品への移行作業に必要な期間を見積もると、契約更新に間に合わない。



  • 移行しやすい状態を維持するために、Microsoft 365に含まれるアプリやサービス上で開発されたアプリケーションの扱いを整理し、以後の開発にガバナンスを利かせる。

  • 更新条件に納得できない場合、代替となる製品 (群) への移行を直ちに進められるように、ペルソナ別の利用実態を把握した上でMicrosoft 365の各サービスの移行先とコンテンツなどの移行方法を準備する。

  • 契約交渉や代替製品への移行に要する期間も考慮してリードタイムを逆算し、交渉の準備を早期に開始する。
