remove old OWA files after cumulative updates?? RRS feed

  • Question

  • I recently discovered a folder, C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\prem, which contains millions of leftovers from cumulative updates, plus fonts.

    What is the best, most appropriate way to clean out this folder and keep it clean??

    Along these lines, is there other housecleaning one should do after running cumulative updates??

    This question is for both Exchange 2016 and Exchange 2013.

  • In my case it's about 1 GB/folder thereabouts so I really would like to remove them non-destructively. :)

  • From what I know, you shouldnt remove those. At least that has been the case in the past.

    Well, totally up to you of course! But 1GB in the big picture is not much and you it would stink if some time down the road you were find out you cant apply a CU or something when it looks for a dir or file that isnt there. Just sayin :)

  • Hi tlyczko2,

    According to my experience, yes, you can delete these folders, but it's not recommended. We cannot guarantee if deleting these folders will result in any potential problems, and once result in a problem, that would  affect the user experience. If you still insist on deleting these folders, please back them up before deleting, that will help us revert it back if any problem occurs and minimize the impact.

  • I meant 1 GB *per* folder, not 1 GB total. :)

  • As stated by Andy and Kelvin, you can delete these folders but it's not recommended to do so. If you want to do this, you may consider to create a scheduled task and clean up the folder with script. For your reference:
