Hi, before upgrading to Office 2016 from Office 2007 I didn’t have this issue but now it takes hours to export the Outlook data.
I have been used to cloning my main drive to an identical 250gb SSD so if I come across a serious problem I just swap drives and re-clone to what was the problem drive. I find this saves time but it does mean I have to back up my mail to another drive and then import it again after swapping drives.
Lately after installing Win 10 updates especially the ‘creative’ update which left me with no ‘text’ anywhere, I have had to do swap drives a few times.
The problem is that the time taken to import and export has increased, the last effort taking most of the day. If I cancelled the export the system would freeze and I would have to re-boot.
I noticed that ‘Exporting Calendar’ shows several times whilst in the process of exporting (this would be repeated showing different lengths of time i.e. 30mins- 2hrs) so I have been looking for a way to clear any Calendar files in the hope of fixing the problem but have only found instructions that are unclear or don’t relate to what I see in menu’s i.e. relating to Calendar. I don’t actually use the Calendar but when I click the icon I see the message ‘Microsoft Office is preparing the requested view’. This takes a few seconds and then freezes for a while before several calendars show in a column on the left. The last time I clicked on one the blue circle appeared and Outlook froze and I had to restart it.
I was wondering if Calendar data has accumulated due to importing the data several times. My contacts list has individual contacts repeated about 30 times? Overall Outlook is working, it is only in attempting to export it to a PST file that the problem begins again with the Calendar data. Hope you can help.
