Greeting to all.
How are you doing?
Please I wanted to ask you are there any reliable solution concerning exchange store.exe process?
I have notice that even if you upgrade your server ram to 20Gb store.exe will still act the same way.
My server memory usage goes to 98% this causes poor performance mail services, though store.exe is consuming
60% of the Ram, but if I can limit store memory usage to 30% I will be fine.
I will appreciate your advice.
Thank you.

By default, the msExchESEParamCacheSizeMax key is not set, which means the store can allocate the memory it needs dynamically. ESE (store.exe) will grow the cache to consume almost all available RAM on the server if there is no other memory pressure on the system For example, if the server contains 16gb physical memory, if there is no other memory pressure, one could expect that the store.exe process will grow to use up to 14gb memory (16gb minus 2gb allocated to Kernel mode). This much larger database cache size results in greatly reduced disk I/O, and is preferred anyways, as reading information from memory is much faster than reading information from disk. If memory pressure occurs, as when other applications request/require memory, ESE will appropriately shrink the size of the database cache. It’s not recommended to modify the msExchESEParamCacheSizeMax attribute of the information store object. Lowering this value may degrade performance, in terms of server performance as well as in terms of end-user experience.

I have an Exchange 2010 server that is currently using 89% of it's 16GB of memory. This is all that server does so according to the article Zealous posted this is absolutely normal behavior. So I am guessing if I had another application running on that server that had a large memory requirement then Exchange would give some of its memory up.

I understood that it will release some memory to other process if they are in need.
but the thing here is that my server memory is always 98% used.
I want to keep it below 80%
because each time it goes to 98% email uses get the error on WOA that the mailbox is not available.

I guess you could alter the msExchESEParamCacheSizeMax key
