Outlook 2010 send as permissions

Posted on 2013-11-15

I hope someone can help. I have assigned a user send as permissions for about 20 members of our office. I did this in the EMC by simply managing send as permissions as I have done for many users in the past. This time the user will try to send as a certain person and get an error saying they do not have the permissions necessary even though they do. This does not always occur but happens enough to be very frustrating. I double checked the permissions in AD users & Computers and all appears to be correct.
I had read that you can only have 10 mailboxes assigned to Outlook and noticed that the cache of "send as" names seems to stop at 10. We have tried deleting all names but this seems to have no affect. I do not know if the number of users I have allowed one user the right to send as is the issue. Any help would be appreciated.

I believe for them to take effect you have to restart the information store service

Create a Distribution group. Add all the memebrs to this distribution group. Now add this group in send as permission and check.

This idea made a lot of sense to me. I first took all the users and removed the send as permissions I had previously granted. i then created the distribution group and added all the users. I assigned the send as permission to the user and tested it. At first it seemed to work great but by the fifth test email I was receiving the same error. Any other ideas or mods I could make to this idea (I really liked this idea and regardless would probably keep this as at least a partial solution)

I was just wondering if anyone else had any ideas on this subject. The distribution group idea, while it sounds good did not fix the issue. Some emails will send just fine while others will not. I can send from one address and then try it a second time and it will say I do not have permission. There is no consistency to this issue. At any time an address will or will not send as from this distribution group. Any ideas will be appreciated.

Open AD in Exchange server. Locate the mailbox. go to security and add the group. Grant modify permission.
