"unable to send mail, multiple matches found" doc.Send

I have searched a bit and this seems to be a known problem. When we upgraded our Notes to from V7 to V8.5.2 whenever people use an action button in a db that sends mail, it prompts with the error “unable to send mail, multiple matches found”, cause it looks up the name in the Recent Contacts view of the local address book. Any workarounds for this?

Thx

Subject: append your domain

append your domino domain name to the end of each recipient address. this will bypass the address lookup at the client and will let the server do it. So if your domino domain (not your internet domain) is ACME your recipients might look like this:

John Doe/SALES/ACME@ACME (notes user)

Administrators@ACME (notes group)

john.doe@acmeco.com@ACME (internet address)

Subject: tx

thanks paul, will give it a go

Subject: would this work even if we only use the common name normally?

So if the common name is Joe Smith, then it would be Joe Smith@ACME. Would this work?

Subject: yes

what will happen is the e-mail will get deposited on the server then the lookup will be performed by the server. If duplicates are found (or any other error) the sender will get a delivery failure, instead of a pop-up error on the client when attempting to send the e-mail.
