Rooms Resources

Question

Hello,

I have multiple rooms in Exchange and recently I changed the email addresses of the rooms and kept the old email addresses as aliases.

The problem is when I want to book a meeting in Outlook, some rooms are dublicated (appeats 2 times) and some of them appears one time.

Any ideas to fix this, knowing that in the room finder the rooms appears one time but in location field appears 2 times

In attachement 2 photos shows what am trying to explain

Hi Walid,

Welcome to Microsoft Q&A community.

It sounds like the issue might be related to cached data in Outlook. Here are a few steps you can try to resolve the duplicate room entries:

Clear the Outlook Cache:

Close Outlook.

Navigate to C:\Users[YourUsername]\AppData\Local\Microsoft\Outlook.

Delete the .ost file associated with your profile (Outlook will recreate it when you restart).

Restart Outlook and let it re-sync.

Update the Global Address List (GAL):

Ensure that the GAL is updated to reflect the changes. This can sometimes take a while to propagate, so you might need to wait or manually update it.

Check for Duplicate Entries in Exchange:

Use PowerShell to check for duplicate room entries:

Get-Mailbox -RecipientTypeDetails RoomMailbox | Format-List Name,PrimarySmtpAddress,EmailAddresses

Ensure that there are no duplicate entries with the same email addresses.

Verify Room Mailbox Settings:

Make sure that the room mailboxes have the correct primary SMTP address and aliases set up.

You can use the following PowerShell command to check:

Get-Mailbox -Identity "RoomMailboxName" | Format-List Name,PrimarySmtpAddress,EmailAddresses

Re-sync Outlook:

Sometimes, simply re-syncing Outlook can resolve these issues. You can do this by:

Going to File > Account Settings > Account Settings.

Select your account and click Repair.

Check Outlook Web App (OWA):

Verify if the issue persists in OWA. If it doesn’t, the problem is likely with the Outlook client cache.
