In the past whenever I faced any problem or issue on my laptop with regards to Windows, Microsoft Office, Outlook or any other program for that matter my simple resolution was to better reinstall everything. Reinstalling Operating System bought two major problems with it. Risk of losing some or the other data while taking backup and investing around 2 to 4 hours during the entire process, that’s almost a day wasted for a small cause. Last time I used services of Microsoft Answer for resolving error code 0xc1900101. They too took a through backup of my data before troubleshooting (Just to be on a safer side if something goes wrong). They spent around 30 minutes troubleshooting the issue and resolved it without any reinstallation or loss of data. Great tech guys.
