Both Outlook (the native Application) as OWA (outlook web access) are email clients used for MS Exchange Email server. Both support filtering emails.
I wonder if there is any difference, and if so what is the difference in which both applications employ/use/provide email filter rules (e.g. a rule to treat all emails arriving in inbox with a certain criterium (e.g.
Subject email header contained certain words) in a specific way (e.g. to move it into a specific dedicated folder) )
The core difference I suspect - albeit being unable to verify on my own yet - is that the OWA filters are carried out on the server-side and are applied always, while the native application MS Office Outlook email filters are relevant only "locally".
Each rule you create will take up space in a hidden section of your mailbox. This section is limited to 64 KB. The actual amount of space a rule uses depends on several factors, such as how long the name is and how many conditions you've applied. When you reach the 64 KB limit, you'll be warned that you can't create any more rules. If that happens, you'll have to delete or simplify some of your existing rules before you can create more. Some ways you can reduce the space used by rules are:
Is this quote an indication about the difference between the rules in OWA and Outlook Client ? At least outlook client did not tell any limits (such as the 64KB for OWA)
