We need to move our PFs to Exchange online. We are currently in 2012 R2 with Exchange 2013.
We are following: https://lnkd.in/dFumZhkK
The issue starts at step 5 wherein we are supposed to use the script Sync-ModernMailPublicFolders.ps1
This script has the Exchange Online V2 module included. This module cannot be installed unless we have WMF 5.1 which as per MS cannot be installed on a server running Exchange 2013 https://lnkd.in/dnSjHnNh
Now, we have also tried to install the older version of EXO V2: 2.0.3 but that also returns an error when we try to connect.
“Index was out of range. Must be non-negative and less than the size of the collection.”
Who else has done a migration from 2012/Exchange 2013 and faced the same issue – and how was it resolved?

Quick fix? Install a windows 2016 server with exchange 2016 ... use it as the connection with the cmdlets you need.
When everything is migrated cleanup the 2013 and use the new exchange server as remote management. Ofcourse you can do also with exchange 2019.
If you dont have a license you still can use this setup for 180 days.
dont forget to quick configure the spn to exchange 2013 back or just configure all the important stuff on the new exchange.
