I have a problem I am running Exchange 2013 recently upgraded to service pack one hoping to fix the problem no luck changed the ConnectionTimeouts on the recieve connectors no luck, diasabled certain commands chunking and BinaryMime no luck I can recieve
large attachements internally and send to external users but no user is able to recieve emails with attachments bigger than 1 MB all formats doc,xlsx,pdf etc and there is no NDR the attachment is either stripped or the email disappears into thin air literary.
I am about to lose my mind over this. This started a month ago howcan I test at what point between the sender and myself the emails are being filtered all other emails come through as long as the attachments are less than 1 MB.
