How Do I Change Message Size Limits in SBS 2008/2011 Standard

Size limits for email messages are controlled in a variety of places in Exchange. Settings are placed globally at the transport level, on each individual send or receive connector, at each individual mailbox, and controlled at individual web applications such as EWS and OWA . Your business needs should determine if you need to change these settings and at which location(s). In order to accomplish this successfully, you must know that more restrictive settings override less restrictive settings as you flow up the chain from individual mailbox settings to SMTP connectors and finally to global transport settings.

How To Identify Bad Items In Public Folder Replication

there are various things that will prevent an item from replicating to an Exchange 2007 or Exchange 2010 public folder store – things like bad start/end dates on appointments, category names that contain certain characters, etc. However, once you’ve figured out that replication is failing because of one of these problems, it can still be tricky to identify which particular items are the ‘bad’ items. In this post, I want to share the approach we usually use to track these down. Now, you may be thinking, “Well, I can just compare the source and the destination to see which items didn’t make it over, and those are my bad items, right?” Not quite. When we replicate changes for a particular folder, we pack up as many changes as we can until we meet the Replication Message Size Limit configured on the public folder store. This applies to both the replication of new data and the backfill of existing data. As a result, when you observe a backfill response for a folder with a bunch of messages, you typically see a big list of items in the event: (more…)

If you have to enable SMTP relay in Exchange 2007 or newer, be smart about it

Relaying: The easy way, and the secure way The best way to allow unauthenticated relaying, or certainly the more secure and recommended one, is to create or use a Receive Connector dedicated for this purpose. I recommended this approach even on Exchange Server 2003/2000 — it’s not a good idea to use your Internet-exposed SMTP virtual server to allow anonymous relaying, even if restricted to specified IP addresses.
