Im at the end of my wits with this issue. I have been troubleshooting this issue for 2 days now and now another user is experiencing this problem. So please any expert advice is appreciated.
Our company is going through a merger so we have:
users on oldserver1.domain -- os1.domain(using 2003 exchange server)
users on oldserver2.domain -- os2.domain(using 2007 exchange server)
users on newserver.domain - ns.domain (using 2010 exchange server)
Clients use XP, 7.
Client use a mixture of outlook Outlook XP - Outlook 2007
One user received an email generated by another server with a PDF attachment.
User(Outlook XP) attempts to forward email with attachment (CONFIRMED IN USER's SENT BOX) to User2.
User 2(outlook 2007) receives email but no attachment.
User sends email with attachment to user (using forward method) to User3 and User3 receives email and attachment (outlook 2007)
User 3 sends email with attachment to user 2 and user 2 receives email with attachment.
This morning user1 can send attachments to user 2 and user 2 receives.
Attachments forward from user3 to user 2 are not received now.
Message original format is Plain Text to User1 and is sent as Plain Text.
Confirmed attchments are missing in OWA (Webmail)
Removed all temporary internet files associated with Outlook.
Configured user on a new system and setup and still no attachments with email.
Send email in all 3 different types of formats (rich text, HTML, plain)
U2 is on new domain
U1,3 is on old domain
U1 -X-> U2 U1 ---> U3 U3 --->2
U1 ---> U2 U1 ---> U3 U3 -X->2
If I save the attachment to my desktop / or send a file as an attachment regularly U2 gets the email plus attachment.
If forwarding the emails with appropraite formats user does not get attachment.
Any help is greatly appreciated.
