Outlook에서 CloudM Migrate 마이그레이션 날짜 수정

CloudM Migrate handles 사서함 transfers by downloading messages from the source system and uploading them to the destination. When the destination is a Microsoft Exchange or Microsoft 365 environment accessed through Outlook, each uploaded message receives a new Received 헤더 from 대상 메일 서버. This Received 헤더 contains the timestamp of the migration, not the original delivery date.

Outlook desktop determines the date displayed in 받은 편지함 by reading the most recent Received 헤더 in each email's 헤더 체인. Since the CloudM migration header is the newest, Outlook shows the 마이그레이션 날짜 for every single message. The original Date 헤더 still exists within the email, but Outlook prioritizes the Received 헤더 for its "Received" column display.

This is 특히 problematic for 사용자 who rely heavily on Outlook's date-based sorting and search. After a CloudM migration, 받은 편지함 becomes an undifferentiated mass of messages all stamped with the same date. Finding a specific email from a specific time period requires opening each message individually and checking the original Date 헤더 manually, which is completely impractical for 사서함 with thousands of messages.

Outlook's "Received" column shows the 마이그레이션 타임스탬프 for every email. Date-based sorting becomes useless because all messages are grouped under a single date. The "Arrange by Date" view, which is Outlook's default, presents the entire 사서함 as one flat block instead of the familiar chronological groupings (Today, Yesterday, Last Week, Last Month, Older).

Outlook's Quick Search and Advanced Find features are impacted when filtering by date. Users who search for "emails received last month" or "emails from January" get no results (or all results, depending on when the migration occurred) because Outlook searches against the corrupted Received date. Outlook rules that process emails based on when they were received also malfunction. Auto-archive settings that move emails older than a certain date fail because Outlook sees every email as having the same recent received date.
