We're migrating 8400+ folders and 300GB of public folder data to Office365
We've encountered 1482 failed and skipped elements - yes, we configured a bad item limit or Unlimited. Looks like large items - that is items larger than 49MB fails - not documented anywhere.
But still - the error we struggle with is the 1482 skipped elements - Skipped ITEM Folder ACL - reason CorruptFolderACL
O365 support says we - most likely - can look away from those errors. But hey - what if I'd need to reset permissions on 1482 folders - not likely.
And - going through PublicFolder permissions on EX2007 server I see that my migration user have all administrative permissions, and author for Client Permissions. Any unresolved SIDs (deleted users) are removed from ACL aswell ---
i say "what the heck"
O365 support says - "strange"
me again "what the heck"
Browsing the web I see some cases with this error - but never what the impact or solutions are.
and O365 said "perhaps you can try PST import on your 8402 public folders" - I haven't stopped laughing yet ...
