Attention: This page is scheduled to be removed on June 30, 2014. Please refer to the Message Center in the Office 365 admin portal to stay informed about changes to your Office 365 service, including new features and actions you need to take to keep your service running smoothly.


This page documents known issues that have been identified by Microsoft Customer Support and Service as a direct result of customer experiences during the upgrade.

The issues documented here may be temporary and/or edge cases and/or minor notations about the upgrade experience.

 

1-Nov-13 High shared mailboxes usage may increase network traffic.

If you have a large number of shared mailbox resources (which can include shared calendars, delegated access, contact sharing, etc…), you may see an increase in the number of connections from Outlook to Exchange post Service Upgrade or post migration to Office 365. In this situation, you need to ensure that network infrastructure (including any proxies, firewalls and all routers) can handle the connections. The potential workaround for a proxy that cannot handle the session load is to bypass the proxy for connections to Office 365 for Outlook.

For more information, please see the Office 365 Deployment Guide.

 

12-Sep-13 Removing and reading Exchange licenses during upgrade may result in a user's mailbox becoming inaccessible temporarily.

While the service upgrade is in progress, please do not reassign licenses to existing users. In some cases, a user's mailbox can become inaccessible when Exchange licenses are removed and restored. If you encounter this issue, please be aware that the problem will be resolved when the service upgrade is completed.

 

12-Sept-13 Office 365 Exchange Online Kiosk users may be unable to delete or move emails while Service Upgrade is in progress

 While the Office 365 Service Upgrade is in progress, Kiosk users may receive the following error:

 “Access Denied.  The error report is listed below: Access Denied”

 

This issue may impact users when attempting to move messages between folders, or when attempting to delete messages in OWA.  These users may also be unable to add attachments to email messages, as the pop-up screen to add the attachment may not be displayed.

 

As a workaround, Kiosk users can access OWA through the direct outlook.com address and the organization tenant name.  For example, for a tenant name contoso.onmicrosoft.com, the URL would be “https://outlook.com/owa/contoso.onmicrosoft.com"

 

28-Aug-13 Depending on the implementation used on third-party mobile devices that connect to Office 365 via Exchange ActiveSync, users may experience intermittent connectivity and other problems during and after the service upgrade.

Microsoft Exchange ActiveSync enables devices to synchronize your Inbox, Calendar, and other items with Microsoft Exchange Server mailboxes. Some customers are experiencing issues during and after the service upgrade with some mobile devices, such as Android and iOS devices, that synchronize with Exchange by using Exchange ActiveSync. 

 

This article lists a set of known issues that Office 365 customers are experiencing accessing Office 365 via the Exchange ActiveSync software provided by third-party mobile device manufactures. Third-party mobile device manufacturers provide the Exchange ActiveSync software that is used on their products. Microsoft can assist in investigations of issues with mobile devices manufactured by third-party vendors, but cannot change or update the implementation of the EAS protocol on the device.

 

21-July-13 Outlook users experience Long delay in connecting to the Exchange server after you receive the service upgrade for Office 365

This issue occurs because you have access to other mailboxes that are automapped to your profile. Or, you have an online archive associated with your mailbox.

 

Update 27-Aug-13: This issue has been resolved for Outlook 2010.  Please reference KB 2862373

 

17-July-13 Cloud mailbox users may not receive internal Out of Office replies from on-premise mailbox users when Exchange Hybrid is deployed

 

Exchange Online Cloud Mailbox users may not receive internal Out of Office replies from on-premise mailbox users.  This does not impact other on-premise mailbox users.  Internal Out of Office replies sent from Cloud Mailboxes are not impacted by this issue.  Additional details are available here.

 

12-July-13 Upgrade is marked "complete" but FOPE hasn't been upgraded to EOP

In some rare cases, we may encounter an unexpected technical problem while upgrading your Forefront Online Protection for Exchange settings to Exchange Online Protection, and have to delay completion of this upgrade step.

For more information, please read the FOPE to EOP upgrade delays FAQ.

 

21-June-13 Outlook 2007 users cannot share their Calendar after Office 365 Service Upgrade

Outlook 2007 users may be unable to share their calendar with other Office 365 users after the Office 365 Service Upgrade has completed.  This issue may also impact Outlook 2007 users who onboard directly to Office 365

Users may experience the following symptoms:

  • When an Outlook 2007 user attempts to share their calendar, they may receive the following error message:
    • Error while preparing to send sharing message

 

  • When an Outlook 2007 user attempts to  check the permissions on their calendar, they may receive the following error message:
    • An error occurred when setting schedule permissions

Details are available in KB 2836889 - You can't share your calendar in Outlook 2007

Current guidance for customers: 

 

 

Workaround:

Outlook 2007 users can access their mailbox using OWA to send calendar sharing messages or to view / change their calendar permissions. 

 

Solution:

Upgrade impacted Outlook 2007 users to Outlook 2010 or later

 

 

21-June-13 Users selected for Early Upgrade that have no Cloud mailbox may not complete Early Upgrade

Users selected for Early Upgrade (Users and Global Administrators) that do not have a cloud mailbox may be unable to complete the Early Upgrade process

 

Current guidance for customers: 

When selecting users to participate in Office 365 Early Upgrade, make sure all Users and Administrators have an Exchange Online cloud mailbox.  If a user selected to participate in Office 365 Early Upgrade does not have a mailbox, the Early Upgrade process may stall

 

 

14-JUNE-13 Outlook folder names appear in a different language after upgrade

  • After a service upgrade or migration, a small number of Exchange Online users will notice that the names of their default Outlook and OWA folders (Inbox, Sent Items, etc.) appear in a different language.

  • Please review this wiki post for the latest information.

 

 

6-JUNE-13 Mailbox size exceeds quota after Office 365 Service Upgrade

PARTIALLY RESOLVED 29-AUG-13
We are increasing mailbox quota for all Office 365 users.

 

If you are scheduled for upgrade after 12-OCT-13 and have never postponed your service upgrade (or had it rescheduled by Microsoft), all users will automatically have their mailbox size increased to 50GB, provided you have not set a lower mailbox size quota.

 

If you were scheduled for upgrade prior to 12-OCT-13, or were scheduled for upgrade prior to that date and either postponed your upgrade or had your upgrade rescheduled by Microsoft, you may not have increased mailbox quotas until the November 2013 timeframe. If this is the case, you may experience the issue below during your service upgrade:

 

Mailboxes appear to increase in size when they are upgraded during the Office 365 Service Upgrade.  If this increase in mailbox size exceeds the mailbox quota, users may experience these symptoms:

      • Users are unable to send email using OWA or Outlook (all supported versions)
  • ActiveSync devices unable to connect, users prompted for credentials.

Details are available in the Release Notes for Exchange 2013 

Current guidance for customers: 

The mailbox size needs to be reduced so the quota limit is no longer exceeded.  Have impacted users’ access their mailbox using OWA or Outlook and remove mail items until the mailbox size is under the quota limit.  If mailbox items cannot be deleted, they can be moved to an Archive Mailbox (if available), or exported to a local mail archive (PST).
