Based on the older version of this article here:
I created the ParameterSystem Subkey, with the Maximun Polling Frequency key and set the Decimal value to 45000.
This was to mitigate the delay issues in Outlook 2003.
Ever since then I receive this error message in my event viewer.
Event 9646, MSExchangeIS
Mapi session "13fbc88b-c9fc-4b9c-9efd-1
4: /o=MYDOMAIN/ou=First Administrative Group/cn=Recipients/cn=MYU
SER" exceeded the maximum of 32 objects of type "session".
Another user get this:
Mapi session "2e5673f1-a3bd-4d56-b988-0
2: /o=MYDOMAIN/ou=First Administrative Group/cn=Recipients/cn=MYU
SER" exceeded the maximum of 250 objects of type "objtMessage".
I have received about 6 of these.
I'm not saying this started as a result of me creating the subkey...Microsoft would have to confirm that.
I'm just saying that this is when I started to notice it.
My system specs are:
Exchange 2010 SP1 Enterprise - Update Roll Up 2
Windows Server 2008 R2 - All updated up until December 12, 2010.
