I wrote in another topic, and really hope to get help from MS:
This is great to read, however, Sharepoint is simply the bane of my helpdesk... Numerous MS staff at events state that Sharepoint/Document libraries is the Microsoft equivalent of Dropbox, and the screenshots from Mover reinforce this.
However, Sharepoint just isn't up to it... The sync utility just "breaks" whenever you reach anywhere near 150k files (despite MS stating 300k), constant desyncs and other issues - I wrote about it here https://www.reddit.com/r/msp/comments/dgzp6w/is_office_365_sharepointonedrive_production_ready/
Today, we have a client who needs ~10k files shifted from within one Sharepoint library to another - doing this via the desktop client and syncing seems to be less than perfect with a few files getting missed and doing it via the UI always seems to hang on large move/copies, so, I am finding that I need to delegate the job to people on my helpdesk to go through folder structures manually to move a few folders at a time to ensure nothing gets missed.
It really just feels like we have gone back in time with sharepoint and it is constantly taking ages to perform what should be simple tasks.
Can I please ask if MS is going to do anything on this front as for a lot of larger companies, it is making Sharepoint almost unusable to the point where we are looking at alternate solutions such as Dropbox or Egnyte.
