I am having a very puzzling problem in trying to export WLM messages from a Windows 7 system and import them into a new Windows 10 computer.   I am going WLM 2012 to WLM 2012.

I initially was trying to export to a Flash drive and then import the files into the Windows 10 computer.  Took about 10 seconds each way - so I suspected it didn't work, and it didn't.  Then I read on this forum about Exporting not working very well (if at all) when going to a Flash drive and the suggestion was to Export to a local folder/file and then copy that folder to the Flash drive.

Well, that was good advice because the Export now appeared to be working and a total of 19,018 files were exported (yes, it took a lot longer this time).  The email is my wife's and of the 19,018 files, 9,908 are in her Inbox (another story).

Anyway, the next step was to copy the Export folder to my Flash drive -- everything OK, so far.  The problem comes in after roughly 18,600 of the files have been transferred to the Flash and then all of the sudden, the transfer speed slows down to about 15 bytes per second (yes, that is right, "bytes per second") and it goes downhill from there.  And the time left to finish transferring the files jumps to 13 hours.  Folder/file size is about 3.47GB. 

So what is going on.  Anybody have a clue as to what is happing to cause this abrupt change, where the transfer speed essentially goes to zero .  I think some of the files being transferred were .eml files.

(I can't figure out WHY Microsoft makes it SO DIFFICULT to move email files.)

(P.S.  I am trying the cloud now, but the upload / download sync is nothing to brag about either -- and I found out through trial and error that it is almost impossible to tell when that is complete, i.e. when the files are finally synced, but that may be just that I am new to the cloud and don't understand all of the sync business yet.)
