Exchange 2010 and SendAs problems

[darrenmcginnis]

Do you mean, in AD U&C, User Properties, Security, Advanced and "Include inheritable permissions from the Object's parent"?

It's unchecked

for mine

Checked for the Helpdesk user

ah, now we may be getting somewhere, is that for the test account to?

For the other mailbox that has the exact same issue, both the general user and the actual user has the inheritance box ticked

mmh, just yours is unticked right? If you check thr send-as permission via the EMC for helpdesk, does it clearly show the name or does it show guid?

They always show the name

The very 1st time you send the email via Outlook it works and any attempts after fail & it always works via OWA? just read the post again & want to make sure it clear? You also mention ABP, how are they configured? Any chance to have a look at this over a webex or something similar?

[darrenmcginnis]

ABP?

What's your day job? Lol

Yes that's right, in OWA I opened another users mailbox and sent it from there. I can't see any other option to send as a different user in OWA

address book policies. Day job, urrm, im learning exch, lol, iman exch admin -

[sukh]

from OWA, did you not choose the From Field to send as?
Outlook Web App (OWA) for Exchange 2010 has the From field option

Never saw that, just tried it and straight away it said "You don't have the permissions required to send messages from this mailbox."
I had to type the email address in as it wasn't a member of the Staff Address GAL

Yeah I had to seperate the Staff and Pupils into separate Address Lists so that the Staff couldn't see the Pupil email addresses and vice versa

For your email address policy, you defo have all 3 smtp domains defined?
And you are 100% sure the the default SMTP address is domain3 and that is what you're trying to out as. It seems like send-as is not working at all. Open another mailbox is different as we have seen it fails in owa too using thr from field.

[sukh]

can you run get-mailbox "helpdesk alias"| fl

100% sure the default domain is domain3 and I don't think the Helpdesk has domain1 on it, but I never use @domain1 for anything. It's just a receiving address.

Can try the powershell command tomorrow. Is the alias the alias in the properties?
