Exchange Server 2003

Problem:
Users wanting to connect to the OWA (Outlook Web Access) Website have to enter https://mail.domain.com/exchange exactly! Quite annoying if you ask me.
Wouldn’t it be better if users could simply type in mail.domain.com ? (The browser will insert http:// on it’s own accord)

Solution:
Go to the wwwroot of the default website (usually C:\inetpub\wwwroot\) and create a new text-file called “OwaHTTPS.asp”. Put in the following:
<%
If Request.ServerVariables("HTTPS")  = "off" Then
Response.Redirect "https://" & Request.ServerVariables("HTTP_HOST") & "/Exchange"
End If
%>

Then, give the local IIS user (Default name= IUSR_) Read + Execute permissions on the file.

Now start Internet Information Services Manager and locate the Default Website. Right-Click, Properties. Go to the Documents tab. Click Add, and type in: OwaHTTPS.asp
Move this new document to the top of the list.
Click OK untill you’re out of the menus. When you get a prompt for the sub-sites, click “Select all” and OK.

Applies to:
ONLY Exchange Server 2003 with SP 2.

Problem:
With MS Exchange Server 2003, and NO service pack, the maximum database size is 18 GB. With the release of Service Pack 2 for Exch 2003, this value is now DEFAULT 18 GB, but can be increased up to 75 GB for Standard versions.

Solution:
Modify the registry settings:
1) Open REGEDIT.
2) Navigate to the following key:
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\
\Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00″
3) Create a new DWORD, with the name (remember caps! – no quotes):
“Database Size Limit in GB”
4) Give your new DWORD the value of the desired size, in GB. So for a 25 GB database, simply enter 25.
5) Restart the Microsoft Information Store from Services.

Thats it.

Microsoft Exchange Server 2003 (verified on 2003, might work on older Exchange servers)

Problem:
A user has deleted one or more public folders by accident, and they cannot seem to undelete them from their email-client, such as Outlook.

Note:
This also works for Contacts stored in Public Folders.

There are two possible solutions to this;

Solution 1: Outlook Web Access.
Go to the OWA website for your Exchange Server, such as:
“https://mailserver/Public/?cmd=showdeleted&btnClose=1″
Then select the folder(s) you want to restore in the main window, and then click the Restore button on the top. Sometimes this method will fail, in that case, move on to the second solution below…

Solution 2: PFDAVAdmin.
PFDAVAdmin is a free tool from Microsoft, get it from Microsoft, or here: PFDAVadmin.exe.
The tool is a self-extracting archive. Once you have it started, right-click Public Folders, select Show Deleted Subfolders. From here, you just select the folder(s) you want to recover, right-click and hit Recover Folder. Presto! Done!
