Hi, Im pulling out (whats left) of my hair...we have a issue where some emails are getting bounced The format of the e-mail address is incorrect. Check the address, look up the recipient in the Address Book, or contact the recipient directly to find out the correct address. <xxxxxxx.xxxxxxxx.xx.uk #5.1.3> I have deleted account, re created.. removed email address, change email address added a second email address.. all with same error. user can send fine. Also, any users that were created more than 3 weeks ago are fine. Nothing has changed on systrem (as far as i am aware). Any one got any suggestions? ( I can give mre details if needed) TIA

Just a addon .. these accounts have been created using CSVDE.. If I create manually, emails work fine...Ive looked at csv & it is fine... no extra spaces in email address...

Still need to figure out why they were broke. Pick one mailbox that's a problem and run this against it: (get-mailbox nameailaddresses | foreach { write-host "`"" -NoNewline -foregroundcolor yellow write-host $_.ProxyAddressString -NoNewline write-host "`"" -foregroundcolor yellow } It'll surround the entire proxy address with a quote (makes it easier to find leading/trailing spaces). Perhaps you have more then one primary address for an address type (e.g. two "SMTP:" instead of one "SMTP:" and another "smtp:"). Or maybe there's no primary proxy address for an address type (i.e none of them are in upper-case). If the data came from a CSV you should also check for more than one "@" in a SMTP address, or a trailing apostrophe at the end of a SMTP address. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
