If Outlook Express suddenly starts displaying warnings that some tasks couldn’t be completed successfully while sending mail, but the Errors tab remains empty (see: screenshot at the end of this post), it’s worth checking if the size of the Sent Items folder hasn’t exceeded 2 GB in size :)
You may check the location of an Outlook folder on the disk by right-clicking that folder and picking Properties. If you don’t want to waste an hour watching Outlook move the messages between folders, you may use a simple file renaming trick:
- Create a new folder in Outlook and call it whatever you want, e.g.
- Click that folder once so that its file is created on the disk.
- Navigate your file manager to the folder on the disk where profile data is kept (I told you above how to find that folder).
- Close Outlook.
- Delete the
newfolder.dbxfile (or another one with a name relevant to the name you used in step 1).
- Rename the
Sent Items.dbxfile to
newfolder.dbx(again, the name you use must be relevant to the name of the folder you created in step 1).
- Run Outlook. Your sent mail should be in the newfolder folder, while your Sent Items folder should be empty.
