Moving autocomplete files between profiles on Outlook 2010/2013/2016

This is the process I use for moving autocomplete data from one profile to another profile when you don't have an Exchange server.  This is applicable for Outlook 2010/2013/2016.

First, send an email from the new mail profile and note the time/date when you sent the email.  This time/date will be important shortly.

Now, go to:
c:\users\%username%\appdata\local\microsoft\outlook\roamcache

You're looking for two autocomplete files.  Both files start with stream_autocomplete . . .

You're looking for one stream_autocomplete file with the time/date when you sent the email just now.
You're also looking for the stream_autocomplete that is much larger and represents the autocomplete for the old profile (this will be a file between 10 KB and 5000 KB) with a time/date that corresponds to the last time you sent an email from the old profile.

We'll call the new file "new_autocomplete" and the old file "old_autocomplete" going forward.

Open Outlook.  Put Outlook offline.

in c:\users\%username%\appdata\local\microsoft\outlook\roamcache . . .

Copy and paste old_autocomplete so you have old_autocomplete and old_autocomplete_copy.

Highlight new_autocomplete and choose rename.  Hit control C so you have the name of new_autocomplete in your clipboard.  Add a single letter to the end of new_autocomplete so new_autocomplete now has a new name.

Highlight old_autocomplete_copy and choose rename.  Paste the name you have on your clipboard.  Now, your copy of old_autocomplete will have new_autocomplete's name.

Close Outlook.
Wait 30 seconds
Reopen Outlook.
Put Outlook onlne.

Test autocomplete.

That's it.
