I'm trying to upload ~20,000 emails from Outlook for Mac (latest version) over EWS.
After copying the emails from a local folder to one on the server (outside of the Inbox) the upload started.
While the upload looks like it's completed (Outlook says the folder is now up-to-date) I only have 2,406 emails within the same folder on the server.
In addition to the above, the server contains one GRP file (around 1GB in size) with the name 2020_1_13.grp that contains all of these emails. The dates of the emails range from 2010 - 2019.
So, we have two issues...
1. Emails not being stored in the correct GRP files.
2. Unable to upload large amounts of emails from a local source.
I have previously raised this issue as a ticket (084-2502ED00-006C) back in October 2019, but was told that all development work is currently focused on MAPI. This original ticket was raised when I attempted the same upload, but over IMAP.
