I am running a migration of Exchange public folders from 2007 to 2013. There is approx 70GB of data in public folders arranged through approx. 5000 folders and I am getting issues running the initial sync with some items being too large.
Searching the folders for large items is apparently not a thing.
I have not found any logs of what these items are, is there anyway to tell before I skip all large items or is there some way to force the large items through?
