I discovered some strange behaviour in the "alert me" functionality of Sharepoint Online. I've set up a alert on a file with the name "CRM process approvals: XYZ.pdf". I recieve a email when something changes in the file, but the url isn't working. The URL I expect:


The url in the alert email:


I tried this with multiple file names, but it seems that it is double encoding the URLs and showing '%2520' instead of '%20'. How to solve this?

  • Does your filename indeed include : (colon) in it? If it does, this will cause the URL to become encoded, and as spaces are pre-encoded to %20, this causes the "double-encoding" where %20 is divided into %25+20 = %2520. – moe Jun 21 '17 at 6:43
  • @moe Thanks. It also happens with files without any special characters. – Citizen SP Jun 21 '17 at 7:33

    I'm still quite convinced that if you have files with restricted characters in their name, such as :, it affects all of the files from the same library/folder. See what are the restricted characters. If possible, could you try to reproduce the behavior on another location where are no files using restricted characters in their name? – moe Jun 21 '17 at 8:55
