The calendar in Outlook 2007 suddenly does not open. Email, contacts, etc work well. I used Diagnostics, which showed no problem, I scanned the PST file and it found errors in 47 folders, which it repaired. However, Outlook still freezes when I want to use calendar. I have created a new Outlook Profile and the calendar function works well!! In conclusion, I guess I have a problem with the calendar function in my current Outlook Profile and the problem does not seem to lie with the Outlook PST File. What can you recommend me to do next in order to address this problem? Should I transfer the PST File to my new profile? If so, how do I do that best?
