I have today got this problem:
E-mail can be received in my normal folders.
Now I can't move them away to 'deleted' or 'archive' folders any more.
I constantly get the error 'Det går inte att kopiera objekten'.
(Can't copy the items / can't move the items)
It is the same regardless of mail account.
I have created a new profile with only my 'outlook.com' account.
I have tried to repair Office, got error code 30029-44 (can't find what that means).
I have uninstalled Office 365 and reinstalled it (with restarts).
Problem is still there.
On another computer, I can access my mail normally, and move items between folders and subfolders as usual.
I have disconnected all my mail accounts (and corresponding PST files), so there is only one account left, and I rarely use that.
So the problem seems to be linked to the Outlook app itself, not any mail account.
I have been using Office 365 for years, now suddenly it seems to be broken totally (Outlook, that is).
Please help!
