One of my email accounts is imap. The inbox having some weird behaviours. I cannot delete or move emails out of this account as I get the message “Cannot move the items. The item cannot be moved. It was already moved or deleted, access was denied or the server unavailable.”
However I can move or delete the same email on another machine running outlook 2013. I tried deleting and recreating the account on the machine running the 2016 preview. I also tried to fix the pst files and this did not work either. I also have Mac running outlook 2016 but there everything is fine.
Under Folder|Purge|Purge Options I had to check the boxes at the bottom of those settings to make items marked for deletion actually disappear. Every time I ‘deleted’ an item, Outlook was moving a copy to imap Deleted Items/Trash folder but was not removing it from the item’s current folder (Inbox or whatever.)
