Outlook Mobile Delegate Access for Exchange Online Mailboxes

Outlook Mobile now supports delegate access to Exchange Online mailboxes. By granting fuil access to a delegate, they can open and work with a mailbox, and send messages using the SendAS or SendOnBehalfOf permissions. The new feature underscores the advantage Outlook mobile enjoys over other mobile Office 365 email clients.

Updating OWA Signatures with PowerShell

OWA stores user signatures in mailboxes, which makes it a lot easier for Office 365 admins to update signatures centrally with just a few lines of PowerShell and some HTML magic. OK, maybe more than a few lines… but it’s a lot less complicated than it is to mess around with the system registry and points the way to how Microsoft might introduce cloud signatures for all Outlook clients.

Adding a Disclaimer to Calendar Meeting Requests

Exchange transport rules are a powerful way to apply different conditions to messages as they pass through the transport service. In this case, we add a disclaimer to calendar meeting requests with a pretty simple rule that works on the basis that it detects a special x-header in meeting requests and applies the disclaimer when the x-header exists.

Adding the Same Mailbox to Multiple Distribution Lists

A question asked what the best way is to add a mailbox to multiple distribution lists. The admin UIs do the job for a few lists, but PowerShell is the way to go when you have lots of lists to process. Two approaches are discussed here: one uses an array as the input, the other uses a CSV file.

New OWA Files View Makes Attachments More Accessible

OWA now includes Files in its “module switcher”). The new module allows fast access to attachments stored in any folder in an Exchange Online mailbox. It’s a neat feature that will please many people simply because it makes finding often-elusive attachments just that bit easier.

New OWA Becomes Default for Mobile Browsers

Not many Office 365 users choose OWA as their mobile client, but those who do will soon be forced to use the new OWA because Microsoft is removing the toggle to allow people to switch between the old and new versions in February, just like they did for workstation versions last July. The new OWA is a fine client, but its usefulness on mobile browsers is not as good as the functionality offered in Mobile Outlook, which continues to be our choice as the best mobile Office 365 email client.

Setting Custom Recipient Limits for Exchange Online Mailboxes

Exchange Online now supports a custom recipient limit for mailboxes of between 1 and 1000. The limit controls the maximum number of recipients a mailbox can add to a message. Think of the fun you could have by setting the recipient limit on manager mailboxes to something small, like 6….

Microsoft Retreats From 1TB Limit for Auto-Expanding Archives – For Now

In November, Microsoft set a 1TB limit for Exchange Online auto-expanding archive mailboxes. Now they’ve retreated and the latest service description says nothing about a limit. The two changes in the service featured little or no customer communications and a total lack of any supporting material, like administrative controls to help manage archive mailboxes approaching the limit. While a limit has gone for now, it will be back.
