I have a few users who use a calendar that is in my organizations public folders. in Outlook2010 I can click the public folders icon bring them up and then right click on the calendar and add it to the favorites and then go up to the favorites within the public folders and click on the calendar then in the calendar tab it is listed under the other calendars. Which is great but when i close out outlook and get back into it the calendar dissapears and i have to do the above steps all over again. I have done everything I know how to fix this issue including changing the mapi32.dll to mapi32.old thinking that might be the issue but nothing seems to fix this. Please any info would be much appreciated.
