Exchange - admin can't access some users
- 
 I have the same set of access to two different users (at least what is shown in Manage Full Access Permission dialog box), yet I can attach to one of their accounts using Outlook, but not the other. The second one constantly prompts me for authentication credentials. Suggestions? I'm guessing there's a script command that will show me the permissions differences between these two accounts, but I don't know what it is - I will try my google-fu now...

 Let's check your permissions first. What Exchange groups are you in? 
 http://technet.microsoft.com/en-us/library/dd638132(v=exchg.150).aspxAfter checking your permissions, lets look at the permissions of the users. The best way to compare them is in powershell http://technet.microsoft.com/en-us/library/aa998218(v=exchg.150).aspx 
 (See Example 2)

 Did that help?

 Not yet. When I run Get-MailboxPermission -Identity mailbox@domain -User "me" I get 
  Which seems to indicate that I should have full access to that users mailbox, but I don't.

 Also, is the user's account locked possibly?

 Any luck?

 I actually have another idea. It sounds really stupid, but I have seen it 4-5 times in Exchange. Reset the user's password. I know it sounds crazy, but recently (and in the past) I had a user that kept getting prompted for credentials from Exchange. He could log in to Windows fine, but could not access mail. After spending a few hours troubleshooting, I finally decided to reset his password. He was able to access his mail after this. He set a new password and was not able to access mail again, but could continue to log in to Windows. I asked him to change his password completely to something totally different. He was then able to access mail again.

 How could this be AV or firewall related? From my desktop, my Outlook, I have around 30 profiles setup in the mail control panel applet. This allows me to switch to any of those users when I launch Outlook. I've granted myself the same permissions on all of those accounts, this is the only one I can't log into so far using my non domain admin account (I'm logged into my local workstation as a non admin user).

This allows me to switch to any of those users when I launch Outlook. Uh - silly question but why? What would be the reason to switch to one of 30 users? And why not just add them to your account? I don't see the rational.

 @g.jacobse I presume he doesn't want their mail in his inbox. I used to have multiple email profiles for a client who had PC's for daytime and nighttime users.

I see that as a personal preference thing. I have all my email accounts in one profile. The inboxes all stay separate anyway in Outlook 2013. Also, I want to have immediately availability of the mail in those accounts. I cannot have that if they are in different profiles. But if I wanted to just have things getting mail that was not something i needed to see all the time a separate profile is not a bad idea in and of itself.

 @JaredBusch LOL...I get ya, but I thought @Dashrender has access to other office users email accounts on his Outlook. 
- 
 I could do what JaredBusch is doing, but unlike him I rarely need to get into those mailboxes so having them all setup inside my profile cluttering things up is undesirable. I suppose I could simplify my life by creating a secondary profile and adding them all to that one, that's an idea I hadn't considered - but at the same time, when I'm working with users, having them see that I can see inside eveyone's email is kinda creepy, even though it's in our company policy that we can AND DO audit their email use from time to time. 
- 
 As for all of those other accounts my account has access to being in a single profile - maybe it's an Outlook 2013 thing, but they are all there now by default. I logged into a new computer, setup Outlook 2013 - bam all of those aforementioned accounts show up in the list down the left side. Perhaps I didn't see them on my desktop because I always have my folder list open and there's enough of them that they push the other users accounts off the bottom... Thought I would pass that along.
