Microsoft 365 Migration FAQs

This article provides answers to your frequently asked questions about the migration of your email and calendar to university governed storage in the cloud.

If you have a question about Microsoft 365 which isn't shown here, then please get in touch with us via IT Service Desk.

Can I use OWA to access a Shared Mailbox which is in the cloud if my account isn't?

Shared Mailboxes were migrated into university governed storage in the cloud before the staff mailbox migration. This means that you can no longer access Shared Mailboxes via Outlook Web Access (OWA).

To access your Shared Mailboxes you can download the Outlook App to your PC, laptop, tablet or mobile device. Set up your Outlook account and follow these instructions to add the shared mailboxes you need access to.

Mac users, you should use Remote Desktop to access Shared Mailboxes until your mail account is migrated to the cloud.

Contact IT Service Desk if you have any issues accessing Shared Mailboxes.

How do I "Send From" a Shared Mailbox which is in the cloud if my account isn't?

For Windows PCs: to add the Send From function now that your shared mailboxes have been moved into the Cloud you need to do the following in the Outlook app:

  • Open a new email.
  • Select Options.
  • Select From.
  • Select the drop-down arrow which will give you the option to select your mailbox or another email address.
  • Enter the other email address and you wish to Send From.

Note: You must have delegate access to send from the other email address. However, some people have reported getting a message which indicates they do not have permission to send from the mailbox, even though they do have access. To resolve this follow the steps below:

  • Open Outlook
  • Select File in the top left
  • Select Account Settings
  • Select Account Settings...
  • Double click your email address
  • Untick Use Cached Exchange Mode
  • Select Next
  • Select Done
  • Restart Outlook

Mac users, you should use Remote Desktop to access Shared Mailboxes until your mail account is migrated to the cloud.

What do I need to do before my account gets migrated to the cloud?

Migration experiences on devices such as mobile telephones, laptops or tablets may differ depending on the type of device and operating system, so please read  of the instructions below. Pre-Migration Action is necessary in certain scenarios, please carry out necessary preparations before your advised migration date.

Accessing university data from a Laptop, Tablet or Mobile telephone securely – Pre-Migration Action Required.

  1. Check your Multifactor Authentication (MFA) Preferences. We recommend that you set up Additional Security Verification to Receive notifications for verification via the Mobile App. This is provides the simplest method of MFA approval.
  2. Install the Outlook App, which is available from Google Play and the Apple App Store.
  3. Switch to using the Outlook app prior to migration to ensure a seamless transition. If you currently use another app on your phone to read emails or calendar, this will stop working once your account is migrated.

Please note that some auto-forward and out of office settings may not be transferring correctly during migration, therefore we recommend that you check these settings before and after migration to ensure they are set correctly.

You will no longer be able to access email or calendar data in your phone's designated apps i.e. the default Android and iOS email apps.

To access your work email through an application you must use the Microsoft Outlook App. Follow the instructions below to set up your device:

What will change in Outlook on my work PC?

The migration experience is designed for the University PC desktop access, therefore minimal changes are expected during your migration.

Following migration you will notice that searches for emails will return results based on emails that have been received within the last 3 months. This is due Cache Mode being enabled. Cache mode enables a better experience when using a Cloud based Exchange account which is what has been performed with this migration.

To search emails that are more than 3 months old there will be a link you can click at the bottom of the search results which will enable you to see results that are from prior to the last 3 months.

What will change with OWA?

Microsoft applications, including Outlook, will be available through the university's Microsoft 365 portal at login.gre.ac.uk.

Outlook Web Access (OWA) will not work once your account is migrated into the cloud. If you have saved OWA as a bookmark you should replace it with login.gre.ac.uk.

My account has been migrated and I see shared mailboxes that I shouldn't have access to?

Shared Mailboxes you had access to previously may reappear in your Outlook. This is because your access was not removed by the mailbox owner when your role or responsibilities changed.

Contact IT Service Desk to arrange removal of your access to these mailboxes.

My account has been migrated and can't access my email on my mobile device.

If for any reason you are unable to access email and your method of accessing it pre migration is not working you can access your email via login.gre.ac.uk

  • go to login.gre.ac.uk
  • enter your username@gre.ac.uk and password
  • authorise access via Multifactor Authentication (MFA) if required
  • click on the "Outlook" app to access your email

What is "Cache Mode" / Why can't I see older emails?

When you search for emails, the results you see at first are found from a copy of your mailbox which is temporarily held on your computer. This copy provides quick access to your data, is frequently updated and enables a better Outlook experience. The copy contains emails which have been received or accessed recently.

To search or view emails that hasn't been accessed recently, select the link Click here to view more on Microsoft Exchange and wait a few moments for the messages to download from the cloud server.

Does this affect any other software?

Migrating your email into the university governed storage in the cloud will integrate your email and calendar with our other Microsoft 365 applications and provide a more integrated digital experience. You'll benefit from enhanced functionality and a standardised experience, which you'll recognise when accessing Microsoft Support, including online training, videos and help.
