Microsoft 365에서 BitTitan MigrationWiz 마이그레이션 날짜 수정
BitTitan MigrationWiz 마이그레이션이 Microsoft 365에서 잘못된 날짜를 표시하는 이유
When BitTitan MigrationWiz migrates 사서함 into Microsoft 365, it uses the Exchange Web Services (EWS) or IMAP protocol to upload messages to the destination tenant. During this upload, Microsoft 365's mail infrastructure stamps each message with a new Received 헤더 containing the 마이그레이션 타임스탬프. This header becomes the most recent entry in the email's 헤더 체인.
Microsoft 365 stores this timestamp as the message's INTERNALDATE. Every client that connects to the M365 사서함 (Outlook desktop, Outlook on the web, Outlook mobile, and third-party IMAP clients) reads this INTERNALDATE to determine when the message was received. As a result, the entire 사서함 displays the 마이그레이션 날짜 for every email, 에 관계없이 when the message was originally sent or received.
For 조직s migrating to Microsoft 365 from on-premises Exchange, Google Workspace, or other platforms using BitTitan, this 날짜 손상 affects every migrated 사서함 simultaneously. IT teams face a wave of support tickets from 사용자 who can no longer find emails by date across any of their M365 applications.
Microsoft 365에 미치는 영향
In the Microsoft 365 ecosystem, the impact extends beyond a single client. Outlook on the web (OWA), Outlook desktop, Outlook for Mac, and the Outlook mobile apps all display the 잘못된 날짜. Microsoft's Copilot and AI features that reference email timelines also produce incorrect results because they rely on the same corrupted date metadata.
Compliance and eDiscovery workflows in Microsoft 365 are 특히 affected. Litigation holds, 보존 policies, and 규정 준수 searches that filter by date range return inaccurate results. Administrators who need to produce emails from a specific time period for legal or audit purposes cannot rely on the displayed dates. Microsoft 365's built-in search and the Security & Compliance Center both reference the corrupted INTERNALDATE, making accurate date-based queries impossible without first fixing the underlying data.
자주 묻는 질문
Does BitTitan MigrationWiz corrupt dates when migrating to Microsoft 365?
예. BitTitan MigrationWiz adds a Received 헤더 during the migration process that overwrites the displayed date in Microsoft 365. This is a known side effect of IMAP-based migration and affects all M365 clients and services that reference the message date.
Will fixing dates affect Microsoft 365 규정 준수 and 보존 policies?
Redate.io restores the 원래 날짜s, which actually improves 규정 준수 accuracy. After the fix, 보존 policies, eDiscovery searches, and litigation holds reference the correct 원래 날짜s rather than the misleading 마이그레이션 타임스탬프s.
Can Redate.io fix dates across all Microsoft 365 apps at once?
예. Redate.io fixes the email at the 서버 수준 by correcting the Received 헤더s and INTERNALDATE. The corrected date then appears 자동으로 in Outlook desktop, OWA, Outlook mobile, and any other client connected to the Microsoft 365 사서함.
