I recently upgraded a user from a standard Pop3 email account to a Microsoft Exchange Office 365 email account. The upgrade went great and all the email was transferred, but the user complained about their auto-complete email contacts were not showing up when they typed a contact’s email address in the “send” field. This user was running Windows 7 and was using Outlook 2010. Here are the steps to retrieve the auto-complete file and use it in the new profile.
Step One: Close Outlook
Step Two: Browse to the RoamCache where the auto-complete file is stored. (location is C:\Users\”user.name”\AppData\Local\Microsoft\Outlook\RoamCache
Step Three: Rename RoamCache to old_RoamCache
Step Four: Open Outlook, and create a new email and put a valid email address in the to. . field. Close the new email ( you don’t need to save ). Close Outlook
Step Five: Step 4 creates a new Stream_Autocomplete_”long GUID….xx”.dat DAT File of 1KB in a new RoamCache folder.
Step Six: Change the extension of the file in Step 5 from .dat to .dat22
Step Seven: Copy the original Stream_Autocomplete…from old_RoamCache & paste into the RoamCache folder
Step Eight: Copy the GUID string from the .dat22 and replace the GUID of your previous Stream_AutoComplete
Step Nine: Open Outlook, all of your previous auto-complete entries are now available.
I hope this helps. Special thanks to femi for making my day a lot easier. This post was posted by techspeeder.
