I needed to install .NET 4.7.1 to allow updating Exchange 2013 to CU 21.
This is the installer I downloaded and tried to install: https://www.microsoft.com/en-us/download/details.aspx?id=56116

When performing mailbox migrations using the New-MoveRequest, the movement is performed online while the user is using the mailbox without suffering outage until the end.

A user asked me the way to grant permissions to other users to access to some of his mailbox folders. And for certain folder only read-only permissions.
Let’s suppose “testuser1” wants to allow accessing some folders to “testuser2”.
Permission configuration (Outlook)

Last week I was testing the IMAP/SMTP connection of my Exchange 2013. Unexpectedly Outlook returned the following error:

Stop using Outlook to export and/or import PST for your mailboxes. By using the Powershell commands (New-MailboxExportRequest and New-MailboxImportRequest) I have saved much time. And they come with some useful options.
Here some simple and interesting examples:
Simple mailbox export
[PS] C:\> New-MailboxImportRequest -Mailbox "user1" -FilePath "\\MYSERVER\PST\user1.pst"
The path must be an UNC path, a shared folder. After executing the … Read more
When export a PST using the New-MailboxExportRequest command, a UNC path is a mandatory parameter to set the target folder where the PST file will be saved.
Probably, that folder will not have the correct to permissions to allow Exchange to write into it, so the command would return this error:
[PS] C:\> New-MailboxExportRequest "user1" -FilePath "\\MYSERVER\PST\user1.pst"
Unable to open

I created some room mailboxes in Exchange 2010 and gave book permissions to some users using EMC (Exchange Management Console).
Now, after migrating all my mailboxes to Exchange 2013, I need to change some permissions on the room mailboxes. But no way to perform the changes in the web console.
