DOCUMENT:Q90324 17-DEC-2000 [win3x] TITLE :Workgroups Mail and Mail 3.0 Do Not Work with COMPAQ DOS 3.31 PRODUCT :Microsoft Windows 3.x Retail Product PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows for Workgroups versions 3.1, 3.11 ------------------------------------------------------------------------------- SUMMARY ======= Workgroups Mail and Microsoft Mail 3.0 do not function properly with COMPAQ MS-DOS 3.31 due to changes made to the MS-DOS kernel that affect file-sharing capabilities. This is only true for COMPAQ MS-DOS 3.31. Workgroups Mail and Mail 3.0 work properly with MS-DOS 3.3 or later. COMPAQ is the only OEM that shipped MS-DOS 3.31. For Mail to function properly, upgrade to MS-DOS 5.0 or later. MORE INFORMATION ================ Workgroups Mail and Mail 3.0 do byte-range locking of their .MMF files. This enables Mail to lock only portions of the .MMF file rather then the entire file. Changes made to the COMPAQ MS-DOS 3.31 kernel do not enable this to function properly. COMPAQ MS-DOS 3.31 is manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
