Outlook 2013 Cache Emails Not Being Saved

Configuration:

OS: Windows 7

PC: Lenovo X1 Carbon

Software: Office 2013 Pro

I have a user that has an issue with Cached email addresses not being saved when Outlook is closed and reopened. I have tried several things and at complete loss on how to fix it.

Steps I have done:

Clicked Empty Auto-Complete List

Confirmed "Use Auto-Complete List..." was enabled

Deleted RoamCache folder, I even tried to rename it

Deleted Outlook folder in Users>User>AppData>Local>Microsoft>Outlook

Deleted Outlook Profile and created new one

Reinstalled Office 2013 Pro from O365

If Outlook stays open the Auto-Complete works but if the computer is shutdown or Outlook closed it erases it all again. The user doesn't have an issue via Smartphone or iPad. Any suggestions?

I was trying to locate a possible registry key that may be causing this but haven't had any luck finding it.

Ok, I resolved this issue which I still don't know why the above didn't work. I had to close Outlook, go into the RoamCache folder, Copied the name of the Stream_Autocomplete.......dat file, then deleted the file. I copied the exact file type from a working machine over to the folder, renamed it to the original file name. Opened Outlook, sent a few test emails, closed/opened Outlook, Auto-Complete working still.

Hi,

The file that you replaced is a type of Autocomplete cache in Outlook. Based on your description, the previous one might have been corrupted so the issue occurred, replacing it with a new one fixed it.

I'm glad to hear the it's working now. :)
