The limit is based on total size, not number of rules, so one user might have 20 rules while another has Exchange and older were limited to just 32 KB worth of rules. Later versions of Exchange dropped the lower default setting and gave everyone the maximum KB. This includes Office Exchange and Outlook. Administrators can lower it. This increased storage space allows in the neighborhood of rules, or about 90 more than I want to manage in the Rules dialog.

Really old versions of Outlook stored client rules in the client and server-based rules used the limited storage space, allowing users to have many more rules.

This little trick no longer works as all rules, both client and server, are stored on the Exchange server and subject to the size limit. If you mailbox rules quota is less than KB, your Exchange administrator can increase the limit, up to the maximum of KB, using the following cmdlet in the Exchange management shell to raise the limit to KB. To check the current limit for a user, open Exchange Management Shell and run get-mailbox username select name,rulesquota.

If users still hit the rules limit, they need to review their rules to see if any can be combined or shortened. The use of search folders or custom views may be able to reduce the number of rules in use. See the tools listed below to overcome this limitation and for better rules handling.

Outlook rules help users organize their mailboxes. Thanks to them, sieving spam from important messages can be more automatic and users mailboxes can look less chaotic.

That is the bright side of Outlook rules. The less bright side is that users highly depend on them and every time there is an issue concerning the rules, admins find themselves to be in the eye of the storm.

Outlook rules give users the ability to control and organize their mailboxes content. At the same time, those rules generate problems with the messages.

Below are the most common problems Exchange Server admins come across:. John receives a message from Tony with the subject Important. The first one should move all messages from Tony to the Co-workers subfolder. The second rule is supposed to move emails with the subject Important to the Important e-mails subfolder. In this situation, the message from Tony will go to the Co-workers subfolder and the second rule will not be enforced due to the conflict.

But the real problem begins, when server-side and client-side rules mix. When the Outlook client is offline, server-side rules will be executed first, even if they have a lower priority. If the first rule is client-side and the second one is server-side, the message will be moved to different folders, depending on whether the client is running or not.

The ability to create such rules often leads to emails either being duplicated, going missing or going to a wrong recipient.This website uses cookies for web analytics and marketing purposes.
