I was wondering if someone could help me out, I'm currently getting reports from my clients that they can't send out e-mails with attachments over 5 MB. The send and receive connectors are currently set to 10 MB. This just started happening with in the last couple of days and I have not changed anything on exchange for a long time now. Any ideas?

1) Increase send connectors and restart "Exchange Transport Service." 2) While on Edge, start a synchronization to your Hub.

Did u check the organization limits?

Organization and Server limits are is set to 10MB limits. I have tried raising the limits and it hasn't made a difference.

When are they getting the error? sending outside of the org, or inside?

Hi, Did you use any SmartHost? If so, please check it on that server. Thanks Allen

Just verify message limits at below levels… if all are set then you may need to check ScanMail settings... Global Limit Send Connector – On Hub & Edge Transport Server Server Limit – for any Transport Rules. Exchange 2007 - Message Size Limits Managing Message Size LimitsDinesh
