In June 2018 Microsoft released Cumulative Update 21 (build 15.00.1395.004) which is the last planned quarterly update for Exchange 2013 (https://blogs.technet.microsoft.com/rmilne/2018/06/19/exchange-2013-cu21-released/)
I was not sure about updating my Exchange 2013 directly from CU12 to CU21. It is supposed to be supported by Microsoft. Maybe I could install an intermediate CU before but, anyway, I decided to move on.… Read more
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.
Only when completing the movement there are some seconds during which the user mailbox is not online.
Thats the reason to use the parameter “SuspendWhenReadyToComplete“. It moves almost all the mailbox except the … Read more
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)
First of all, “testuser2” must have “Reviewer” (read-only) permissions on the mailbox root
Then, configure the permission … Read more
Last week I was testing the IMAP/SMTP connection of my Exchange 2013. Unexpectedly Outlook returned the following error:
The message does not appear completely but seems to be “550 5.7.1 Client does not have permissions to send as this sender”. Obviously the user does have the permissions (the user was the owner of the mailbox itself).
Thanks … Read more
Exchange 2013 can produce IMAP issues when trying to authenticate. This is a known bug in CU9 and CU10 but in my CU12 scenario also happens.
The IMAPSettings EnableGSSAPIAndNTLMAuth atribute must be set to False in order to solve the problem.
Yesterday, when one of my users asked me how to configure the email client using IMAP I realized … Read more
When I was migrating my Exchange platform from 2010, I ensured that the backups using Veritas NetBackup were also working in Exchange 2013, both against the active or passive node of the DAG, and also the granular backups
At a certain moment, the backups started to fail (thanks I am monitoring the transaction log disks free space using … Read more
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.
The only way to view and modify booking permissions is … Read more
Some users notified me that some external recipients could not open sent attachments.
After some tests I realized that the problem only appeared for external contacts.
When sending this email…
to a contact configured in the Active Directory, the Gmail web client showed this:

My users notified that … Read more
