Hi I'm receiving this error in my Exchange 2007 Server every hour: Error updating public folder with free/busy information on virtual machine ICOMAIL. The error number is 0x80070005. I used Err.exe program to see what is that, and the outcome is: # for hex 0x80070005 / decimal -2147024891 :COR_E_UNAUTHORIZEDACCESS corerror.h# MessageText:# Access is denied.DIERR_OTHERAPPHASPRIO dinput.hDIERR_READONLY dinput.hDIERR_HANDLEEXISTS dinput.hDSERR_ACCESSDENIED dsound.hecAccessDenied ec.hecPropSecurityViolation ec.hMAPI_E_NO_ACCESS mapicode.hSTIERR_READONLY stierr.hSTIERR_NOTINITIALIZED stierr.hE_ACCESSDENIED winerror.h# General access denied error# 11 matches found for "0x80070005" It is speaking about access denied, but I don't know what to do. Thank you for any help.
