Having issues with Outlook 2016 not responding for many of my users. Version of FSLogix: 2.9.8111.53415. Many users have .OST's larger than 5GB. For Outlook Cache mode what do you use or recommend? 3 Months, 6 Months, 1 Year? We were using 2 years but went down to 1 year. Now we are thinking of setting this to 6 months. Noticing the following event log entries. Anyone have any ideas? Problem is due to faulty hardware? Looking for some FSLogix Ninjas here to shed some light on this. Microsoft has the following list that summarizes expected behavior based on the size of your Outlook data file. Anyone thing that the .OST files are too large? • Up to 5 GB: This file size should provide a good user experience on most hardware. • Between 5 GB and 10 GB: This file size is typically hardware-dependent. Therefore, if you have a fast hard disk and lots of RAM, your experience will be better. However, slower hard disk drives, such as drives that are typically found on portable computers or early-generation solid-state drives (SSDs), experience some application pauses when the drives respond. • More than 10 GB: When the

.ost

file reaches this size, short pauses begin to occur on most hardware.
