EXCHANGE   Exchange – Setting automatic completion time for Mailbox Move Request

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

EXCHANGE   Exchange – Mailbox folders permissions to other users

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
Exchange – Mailbox folders permissions to other users 1

Exchange – Mailbox folders permissions to other users 2

Then, configure the permission … Read more

EXCHANGE   Exchange – SMTP error: 550 5.7.1 Client does not have permissions to send as this sender


Last week I was testing the IMAP/SMTP connection of my Exchange 2013. Unexpectedly Outlook returned the following error:
Exchange - SMTP error 550 5.7.1 Client does not have permissions to send as this sender

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 – Exporting/importing mailboxes to a PST via Powershell

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

   Exchange – “Access to the path is denied” – New-MailboxExportRequest

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

EXCHANGE   Exchange 2013 – Assign permissions to book room resources

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

EXCHANGE   Exchange 2013 – Emails sent in TNEF winmail format

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…
Exchange 2013 TNEF Remote Domain 1

to a contact configured in the Active Directory, the Gmail web client showed this:
Exchange 2013 TNEF Remote Domain 3

The same recipient without existing in Active Directory receives the email correctly:
Exchange 2013 TNEF Remote Domain 2

My users notified that … Read more

EXCHANGE   Exchange 2013 – Solved the “Search results limited to 250” bug

As explained in a previous post (Exchange 2013 – Search results limited to 250), there is reported bug in Exchange 2013 that limits the search results to 250.

Microsoft released CU11 (Exchange 2013 – CU 11 released) that was supposed to fix (among others) this bug. Unfortunately, after updating and testing… no success.
