I have given myself full permission to a mailbox but if I try 'Send As' I get an undeliverable error. Can anyone help?

Sometimes the information store needs to be restarted before the actual permissions apply.  I have also ran into this issue with full access where in the EMC you also have to add yourself with send-as permissions in order for it to work.

I'm not an Exchange expert but I assume this will have to be done 'out-of-hours' to minimize disruption.

yes or wait approximatly 2 hours.  You could add yourself with send-as permissions to test.  Also try testing using OWA for that is tied directly to exchange

Giving yourself Full Mailbox Permissions from the EMC or EMS does not give you Send As Access. This worked in Exchange 2003 but is different in laterversions of Exchange. This is due to 2003 being integrated into AD. Exchange 2007/2010/2013 are separate now.

You can set the Send As permission on the users mailbox by right clicking the mailbox and clicking "Manage Send As Permission". From here you need to add your account, wait for replication and then you should be able to Send As that user.

Send As is an AD permission which is why in Exchange 2007/2010/2013 it does not work simply adding "Full Mailbox Permission".

You can also reference this in Activei Directory. Do the following...

- Open ADUC (make sure that advance features is enabled)
- Find the User
- Right click, Properties
- Select the Security Tab
- Click Advance button

You should see your name under the advance security with "Send As". If this is correct you have Send As permissions over this account.
