Outlook 2010 With exchange 2010 “Cannot open your default e-mail folders.

Issue 1. Error: Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost)

Issue 2. Error: Cannot expand the folder. The set of folders cannot be opened. Your server administrator has limited the number you can open simultaneously. Try closing messages you have opened or removing attachements and images from unsent messages you are composing.

Causes?
– Encyption
– RPC/HTTPS?
– Mailbox Moves?
– Cache Mode (Try Online mode?)
– Max connection limit? Exceed Mapi Session (Explore Exchange Servers)
– Exchange Services? IS Store running,  RPC Client Access running.
– Mailbox Replication Service and Bad Items ( Corrupt Mailboxes?) – Due to frequent recreation of mailboxes? MFA?
– Check Self-Signed Certificate  (EX13)
-Outlook Version needs updating?
–MSO 2010 You currently have version 14.0.7187.5000. There are more recent versions of files available for Outlook 2010.

 

Troubleshooting Performed:

TBD:

Disconnecting the mailbox and then re-connecting it? Disconnecting should remove the exchange attributes on the user account in AD. Then Reconnecting the mailbox should fix any permissions and other issues.

Client Side:

  1. Restarted PC X
  2. Log off and restart Outlook X
  3. Run Outlook in SafeMode Outlook.exe /safe X
  4. Ensure Outlook is not in compatibility mode X
  5. User Profile was recreated, same issueX
  6. Checked access from OWA, works X
  7. Reset all profiles (includes local configurations and settings) Removed: HKEY_CURRENT_USERSoftwareMicrosoftWindows NT CurrentVersionWindows 
    Messaging SubsystemProfiles X
  8. Recreated mail profile > setup for RPC over HTTPS (fast network) X
  9.  Check LAN settings; ok 

Not tested yet.

1. Test user profile using another windows profile
2. Test loading another user profile using same windows profile
3.  Disconnect and reconnect mailbox
4.  Run a scanpst against the OST
5.  Run a mailbox repair

Exchange Side:
1. Ensure Exchange Services are running – IS Store, RPC-CA
2. Verify autodiscover is enabled and internal URL is configured

Logs:

Solutions that worked so far:

  1. EMC mailbox move from one database to another seems to resolve the issue

 

References:

You may need to move mailboxes in the following scenarios:

  • Transition   When you transition an existing Exchange 2007 or Exchange Server 2003 organization to Exchange 2010, you move mailboxes from the existing Exchange servers to an Exchange 2010 Mailbox server.

  • Realignment   You can move mailboxes for realignment purposes. For example, you may want to move a mailbox from one database to a database that has a larger mailbox size limit.

  • Investigating an issue   If you need to investigate an issue with a mailbox, you can move that mailbox to a different server. For example, you can move all mailboxes that have high activity to another server.

  • *** Corrupted mailboxes   If you encounter corrupted mailboxes, you can move the mailboxes to a different server or database. The corrupted messages won’t be moved.***
