Microsoft Outlook issues with Outbox, Sent Items and Autocomplete on and off BUG
When you send an e-mail message in Microsoft Outlook, the message may remain in your Outbox folder as shown in the following figure and when you try to write a new email the autocomplete may not work. Sent Items Folder will not show sent email.
When this problem occurs, the message remains in your Outbox folder until you manually initiate a Send/Receive operation (for example, press F9 or select send or receive) But the email will not show on the Sent Items Folder
We are not sure why this is happening yet but it seems to be some kind of Binary error. This means it happens half of the time that Outlook opens and you can easily identify it by trying to write an email and autocomplete wont work. or it will
The only ones we found so far are:
-Replace Office 2019 for Office 365
We have note tried yet:
-Create a new profile in windows and try again.
-Uninstall office and clear all folders and registry values left. Then reinstall again.
