When I try to send a message with an attachment, my message won't deliver (BANNED FILENAME).

Your problem probably falls into one of two categories:

  1. Your extension is not allowed. Some file types are prohibited from being sent from Outlook Web Access entirely. These include those file types with the following extensions:

    • ade, adp, app, asx, bas, bat, chm, cmd, com, cpl, crt, csh, exe, fxp, hlp, hta, inf, ins, isp, js, jse, ksh, lnk, mda, mdb, mde, mdt, mdw, mdz, msc, msi, msp, mst, ops, pcd, pif, prf, prg, reg, scf, scr, sct, shb, shs, url, vb, vbe, vbs, wsc, wsf, wsh

    If your file falls into this category, you cannot send the file as-is. You can either rename the file (i.e. change the extension), send it, and then ask the recipient to rename it to change the extension back, or compress the file into a zip or rar archive before you send it.

  2. Your extension is allowed, but only if you save a copy on your file system (i.e. on your computer) first. These include those file types with the following extensions:

    • htm, html, htc, mht, mhtml, shtm, shtml, stm, url, xml, dir, dcr, plg, spl, swf

    If your file falls into this category, make sure that you save a copy of the file to your computer before sending (e.g. if you are trying to forward an attachment).
