Excel's Copilot function is headed for the Recycle Bin

The Register 1 month ago 39

Microsoft will retire Excel’s COPILOT() worksheet function on September 14, 2026. The function, previewed in August 2025, will no longer be available starting that date. From then on, Copilot help must come via the Copilot side pane instead of calling the function from a cell, and Microsoft updated its roadmap to cancel the planned general release in 2027.

Microsoft blames AI for delayed Exchange update, can’t say when it will arrive

The Register 1 month ago 35

Microsoft’s Exchange Server team said Exchange SE Cumulative Update 1 (CU1) was delayed because AI tools used to find bugs created additional validation, fixing, and testing work. The company previously indicated CU1 would arrive by the second half of 2026, but it still has no release date. Microsoft says CU1 will be released after it reaches a stable point and plans to wait for a month without a “pressing security payload,” so the timing remains uncertain.
