When attempting to add an Archive Manager (AM) instance as storage in Recovery Manager for Exchange (RME) the previously used credentials are used. (4253606)

Consider the following scenario:

1. Launch Recovery Manager for Exchange (RME) console and attempt to add a storage from Quest Archive Manager (AM).
2. Logon using Windows authentication credentials for User A.
3. It will display the mailboxes assigned to User A in AM
4. Attempt to add another storage from Quest Archive Manager this time using the credentials for User B
5. Expected:  Return mailboxes assigned to User B in AM. Actual result: displays mailboxes User A can access in AM (i.e.same results as in step 3 above)
6. This can also be verified on the AM server by checking the log file AMIOWebService.wlog (it can be seen that the credentials for User A were used in the second attempt even if the credentials for user B were specified)
