I've migrated the public folders from exchange 2010 to exchange 2013 and I'm using the newer mapi connection method for outlook clients but now I get this error message
"Cannot display the folder. You server administrator has limited the number of your items open simultaneously...."
and also I see this error on the exchange server, event ID 9646
"Mapi session /o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=xxx with client type MoMT exceeded the maximum of 32 objects of type Session"
how can I fix this?
