I am still unable to get Outlook Calendar to sync with Method. I have uninstalled the old version and re-installed the new. It worked for a short time, even though I had the old add-in icons as well as the new icons.
Then when opening Outlook, I received an add in error message. I lost the new icons and was left with the old.
Today, I have uninstalled the add-in completely. The old icons still remain in Outlook.
When I try to re-install the new version, I now receive an error message at the end as follows:
"The following Microsoft Office solution cannot be installed due to a general installer error: OutlookMethodSync.vsto"
0x80131604
Not sure what to do at this point.
