I am currently having an issue with an account. 2 people share an Admin Account inbox, while having their own inbox, Although the Admin mailbox only works in Online mode or the folders will not update and emails will not come through.

This is not the problem though.

Before today both people were working fine for the last few months. Now User 1 (only user to send as Admin mailbox) can not send as the mailbox, while in online mode. In cached mode it works fine, however the folders do not work.

When in online mode, i can remove the address from the From: drop down and re-add, however this only works for that email. Sending another email reaches the same error "you do not have the permission to send as blah blah blah". This is a popup error.

Removing the address and re-adding works every time, however as you can imagine, this is not ideal for the user. In testing I have removed permissions for send as in EMC but removing the address from the from field and re-adding is still allowing it to send. It seems outlook/exchange is not recognizing the permissions. Does anyone have any ideas on what could be causing this?

Exchange version is 2011

Outlook version is 2013
