Miscellaneous topics that do not fit into specific categories.
Follow these steps in order, testing after each step:
- Ensure Outlook is fully updated
- In classic Outlook: select File > Office Account > Update Options > Update Now.
- Restart Outlook and test deleting/moving messages again.
- Restart the computer
- Some Office or Windows updates only complete after a restart.
- After restart, open Outlook and try to delete or move items again.
- If using an IMAP account and seeing errors like “Cannot move the items” or “The operation cannot be performed because the message has been changed” when moving mail:
- Switch to a different folder, then back to the original folder, and try the move/delete again.
- If that fails, close Outlook completely, reopen it, and repeat the move/delete.
- If still unable to move items between folders
- Create a new Outlook profile and test there (keep the current profile so it can be switched back if needed). Steps are in Create an Outlook profile in the referenced article.
- Temporary workarounds if the problem continues
- If using Outlook with Microsoft 365/Exchange: use Outlook on the Web (OWA) to move or delete items.
- If using a 3rd-party mail provider (IMAP/POP3): sign in to the provider’s webmail and move/delete items there.
If none of the above resolves the issue and in-app support is available, use Help > Contact Support in Outlook, or if part of an organization, ask the Microsoft 365 tenant administrator to open a support ticket from the M365 Admin Portal.
