[EXCH] Event ID: 9646 User exceeded the maximum of 500 objects of type “objtFolder”.
Shared mailboxes setup in cache mode will download entire content of the mailbox and will register every folder in each cached mailbox toward the objtFolder type limit on the server that’s running Exchange Server. By default, objtFolder limit is set to 500 per-mailbox limit. Once the limit is exhausted, user will start experiencing the symptoms below:
Symptoms:
– Inbox does not update automatically.
– Folder status bar shows “This folder was last updated on …” instead of “All folders are up to date” message displayed.
– Viewing items in secondary mailbox, new folders and items may not appear or seem to be missing.
– Deleted items still appear in the secondary mailbox like shadow items.
– Degraded performance or random hangs.
Exchange Server (Application log) – Error shows:
Event ID: 9646
Type: Error
Source: MSExchangeIS
Description:
Mapi session “/o=First Organization/ou=Administrative Group/cn=Recipients/cn=user”
exceeded the maximum of 500 objects of type “objtFolder”.
Solution 1: Disable Automap and seperate OST for caching (Preferred method)
1. Remove mailbox permissions
Remove-MailboxPermission -Identity <Mailbox ID1> -User <Mailbox ID2> -AccessRights FullAccess
2. Readd shared mailbox permissions without Automatpping
Add-MailboxPermission -Iden
tity <Mailbox ID1> -User <Mailbox ID2>-AccessRights FullAccess -AutoMapping:$false
3. Readd Mailbox from Mail item in Control Panel.
4.Select your profile, and then click Properties.
5.Click E-mail Accounts.
6.On the E-mail tab of the Account Settings dialog box, click New.
7.In the Choose Service section of the Add New Account dialog box, click E-mail Account, and then click Next.
8. Fill in the e-mail with the shard mailbox
9.Click Finish, click Close, click Close, and then click OK.
10.Start Outlook.
Solution 2: Disable caching of all shared folders (placing shared mailbox in Online Mode)
1.On the File tab, click Account Settings in the Account Settings list.
2.In the Account Settings dialog box, click the E-mail tab and then double-click your Microsoft Exchange Server account.
3.In the Change Account dialog box, click More Settings.
4.In the Microsoft Exchange dialog box, click the Advanced tab.
5.Click to clear the Download shared folders check box.
6.Click OK two times.
7.Click Next, click Finish, and then click Close.
8.Restart Outlook.
Solution 3: Increase the objtFolder count using Registry Key
. Open Registry Editor and navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\MSExchangeIS
2. Right click ParametersSystem and create New -> Key
3. Enter MaxObjsPerMapiSession and confirm creation of the new sub-key
4. Right click newly created key, create new DWORD value called objtFolder and give it a decimal value bigger than default 500.
5. Create another DWORD value called objtFolderView and give it the same value.

[EX2010] Litigation Hold (Legal Hold)
Litigation Hold (Legal Hold)
Used to preserve mailbox and electronically stored information in anticipation of legal proceedings, investigations, and unspecified reasons. Organizations may be required to inform when a user is placed on litigation hold.
Specifications:
- Requires Discovery Management or Legal Hold Mgmt (RBAC) to place a mailbox in legal hold
- Option to enable or disable, no option in 2010 to set start and end dates
- Original copies are maintained when modified
- LitigationHoldDate and LitigationHoldOwner attribute is created when enabled
- Migration to O365: mailboxes on Litigation Hold are preserved after a mailbox is moved
Storage:
When a user deletes a folder other than in the Delete Items folder, the message is ‘moved’. When a user deletes from the Deleted Items folder or does a Shift+Delete (Permanent Deletion), the message disappears from the user’s view, is a ‘soft delete’ and moved to Purge sub-folder of the Recoverable Items folder (Recoverable Items folder is also known as the dumpster in previous versions of Exchange). Recoverable Items folder retains items configured on the mailbox database with a default of 14 days. If Litigation is not enabled, items are purged forever based on reaching the quota limit, or longer than the default or set period.
- Default Quota for Recoverable Items Folder, Warning: 20GB, Items: 30 GB
- MFA continues to process the mailbox
- Deleted items are moved retained in a hidden folder called, Recoverable Items (dumpster) with its own storage, and does not count toward the mailbox quota.
- Recoverable Items folder has 3 sub-folders:
- Deletions: Soft Deleted items are moved here, visible from Recoverable Deleted Items (Visible to users)
- Purges: Deleted items from the Recoverable Items are moved here. Deleted Items exceeding the delete item retention period configured on mailbox database or mailbox are also purged here by MFA. Litigation Hold prevents deletion of items from this folder when enabled. (Not visible to users)
- Versions: Original copies of mailbox items are copied here by process called copy on write, where in specific properties changes on the item will create a copy. (Not Visible to users)
Enable and Disabling Litigation Hold:

Set-Mailbox joe@contoso.com -LitigationHoldEnabled $true Set-Mailbox joe@contoso.com -LitigationHoldEnabled $false |

1 |
The Cluster service cannot be started. An attempt to read configuration data from the Windows registry failed with error '2'. Please use the Failover Cluster Management snap-in to ensure that this machine is a member of a cluster. If you intend to add this machine to an existing cluster use the Add Node Wizard. Alternatively, if this machine has been configured as a member of a cluster, it will be necessary to restore the missing configuration data that is necessary for the Cluster Service to identify that it is a member of a cluster. Perform a System State Restore of this machine in order to restore the configuration data. |
- Check the Status of Mailbox Servers by running Get-DatabaseAvaliabilityGroup | FL
- Inspect servers in stopped and started state
- If a mailbox is in a stopped state, you can attempt to stop the individual server by running: Stop-DatabaseAvaliabilityGroup -identity <cluster> -mailboxserver <mailbox server>
- Check the status of the Fail-over Cluster Service Manager
- Launch Fail-over Cluster Service Manager > Manage a Cluster > Enter <cluster>
- Expand the <cluster>, review Nodes
- If a node is stopped, attempt to ‘Start Cluster Service’
- If Cluster Service fails to start, run : Stop-DatabaseAvaliabilityGroup -identity <cluster> -mailboxserver <mailbox server> and perform a Set-DatabaseAvalibilityGroup -identity <cluster>
- If the mailbox server fails to be evicted, reboot the server; ensure mailbox databases are dismounted first or maintenance mode is effective.
- After the restarting, Perform a force cleanup of the cluster from the failed server.
- Log into the failed server, Run Cluster Node “ServerName” /forcecleanup from an elevated command prompt.
- Once the cleanup is successful, Attempt to re-add or remove the failed server back into the cluster. You can also try running Start-DatabaseAvailabilityGroup “DAG Name” –MailboxServer “FailedServer” or Stop-DatabaseAvailabilityGroup “DAG Name” –MailboxServer “FailedServer”
