Outlook Stripping File Extesnsions From Mail Attachments....

[DaveP]

...To External Recipients.

Messages we send to recipients outside the domain [recipients other than those on SchoolExchangeDomain.Local] so if I were to send an E-Mail to:

Staff1@SchoolExchangeDomain.Local from Me@SchoolExchangeDomain.Local with the attachment WordDocument.DOCX

it will be delivered intact [full text, attachment and extension]

However if I send an E-Mail to:

Staff2@GoogleMail.COM from Me@SchoolExchangeDomain.Local with the attachment WordDocument.DOCX

the message will be delivered and so will the attachment but the attachment will arrive as:

WordDocument

or even sometimes:

W1

Can anyone tell me what is causing this? [I do not manage the Exchange server so any information I gain here I will have to forward to the Exchange Manager: Hopefully he will be receptive]

Many thanks.

I though I would bump this thread as it is now becoming an issue with our Governors.

Anyone got anything to suggest?

Anything I might try could help.

Thanks.
