Can anyone shed some light on why is it that, regardless of what prefix I set on a site collection's Document IDs (and, of course, I check the "Reset all Document IDs in this Site Collection to begin with these characters." box) - the document IDs will continue to have the ugly randomized ID prefix that SharePoint sets by default?

Basically, I go to settings, type in the prefix I want, check the "Reset all Document IDs..." box, hit "OK", wait until SharePoint thinks about it. Then when I go back in the same screen, I have a randomized value set as prefix, instead of what I set up.

This is happening again and again. Fully reproductibile.

What do I need to do here!?

  • There’s no way to know exactly how long SharePoint will take to update prefix of document IDs to existing documents, but it should update within a day. Whether this issue occurs now? Mar 10, 2021 at 10:22
  • The IDs ARE being applied, except that they are being applied with the random prefix rather than the one I set. That is quite annoying. Throwing IDs like that on corporate documents is an indication of slopiness - so we will not be able to use that ID in our documents if we can't make some sense of it. Needless to say - I really want to have this issue solved as the feature is extremely useful. Mar 10, 2021 at 10:29

Opened a case with Microsoft and they acknowledged a bug in their system. No resolution time given :(


After you set prefix in the Document ID settings, did you see "Configuration of the Document ID feature is scheduled to be completed by an automated process"? enter image description here How many files in the site collection? The length of the set prefix process is related to the number of files.

  • yes, I did see that. There are really not too many files in there and the process takes a relatively short while (another thing I would like to know is where do I see/set parameters for these processes). The point is that whatever I set the prefix to and hit "Reset all...", it is just re-generates them, using a random prefix value. Mar 11, 2021 at 10:57
  • These processes work in the back end. I suggest you open a service request with Microsoft to check. Mar 12, 2021 at 10:12
