Updated April 14, 2026: We have updated the timing of this change below. Thank you for your patience.<\/p>\n

[Introduction]<\/b><\/p>\n

<\/p>\n

Microsoft Purview Communication Compliance is undergoing an infrastructure upgrade from January 5 to April 30, 2026, causing temporary processing delays, intermittent errors, and possible outdated report data. Although this migration is planned outside of normal business hours, some production clusters may experience higher loads, potentially causing brief delays in downstream processing. Brief delays in processing may occur during this migration, but no data will be lost.<\/p>\n

No action is required, but admins should inform teams about these short-term impacts.<\/p>\n

[When this will happen:]<\/b><\/p>\n

<\/p>\n

This migration will begin January 5, 2026<\/b>, and end April 30, 2026<\/b> (previously April 15).<\/p>\n

[How this affects your organization:]<\/b><\/p>\n

<\/p>\n

Who is affected:<\/b>
Admins managing Microsoft Purview Communication Compliance policies and review workflows.<\/p>\n

<\/p>\n

What will happen:<\/b><\/p>\n

<\/p>\n

    <\/p>\n
  • Updates to policy insights and aggregated counts (New pending today<\/b>, Total pending<\/b>, Total resolved<\/b>) may occur at a slower pace than usual.<\/li>\n

    <\/p>\n

  • Intermittent errors may occur when reviewing flagged messages.<\/li>\n

    <\/p>\n

  • Brief delays may be observed between receiving an alert notification and accessing messages for review.<\/li>\n

    <\/p>\n

  • Certain report views may display outdated data until backlog processing is complete.<\/li>\n

    <\/p>\n

  • Some export functions, such as exporting reports and files, might be temporarily unavailable.<\/li>\n

    <\/p>\n

  • No data loss will occur\u2015only temporary slowdowns in processing times.<\/li>\n
  • Users may experience reduced responsiveness and intermittent instability in the experience.<\/li>\n

    <\/ul>\n

    <\/p>\n

    This maintenance is scheduled outside of normal business hours to minimize impact. However, global organizations may experience some overlap with active hours.<\/p>\n
