I'm currently having a problem with attachments i'm inserting into e-mails using outlook 2010 on a MS 2010 Exchange server.

I start a new email, click 'attach files', browse out to a network share and select 4-5 attachments (under 255 characters) and one of the attachments will be left out randomly without any type of error.

Does anyone have any idea what may be happening here?  It seems like sometimes this works and other times it does not.  Is there a temporary location where these attachments get stored locally before actually attaching itself to the email (possibly causing it to get full and not able to handle it)?

Thank you.

Hi,

Does the issue happen to other users? The attachments missed when adding attachment in Outlook client instead of sending message by using Exchange server. I think the issue should be related to Outlook client in local machine.

Personal suggestion, we can try to add the attachment one by one to the message to check whether the issue persists. Also confirm whether the issue happens to specific attachment. If there is any third-party mail scanning program in local machine, please disable it to have a try.

Additionally, please change a computer to have a try.

Regards,
