I’m a big fan of many applications offering a Dark Mode and I’ve also switched my Office theme to Black.

This works well but the Reading Pane in Outlook remains white and creates a very bright contrast with the Black theme.

I read that there should be a Sun/Moon option somewhere to toggle the Reading Pane dark too but I can’t seem to find it anywhere.

How do I turn the Reading Pane dark as well with the Black Theme enabled in Outlook?

We need to perform an action in Outlook as an administrator. I logged on as the administrator of the computer, but I still can’t perform the action.

How can I start Outlook as an Administrator on Windows 10?

When searching in Outlook, I see a group of “Top Results” before showing all other emails relevant to my search query.

I find this confusing since some of these emails are quite old and are now shown at the top and no longer chronologically.

Is there any way to disable these Top Results?

I noticed that Outlook’s search feature is case insensitive and I’m looking for an option to change this.

The reason I ask is because I have several friends and relatives that have names or last names that are also common words.

For instance first names such as; Hope, Sky, May, Norm, or Guy. And maybe even more frequently for last names such as; Brown, Winter, Black, Baker, Cook, or Young.

So when I search for their names, I get a lot of emails returned which contain the word instead of the name. With a case sensitive search, I hope to be able to distinguish between the two.

Is there a way to perform case sensitive searches in Outlook?

I’ve imported the holidays into my Calendar but unfortunately, these days are not marked as Busy or Out of Office but as Free.

This means that when someone tries to schedule a meeting with me on a (regional) holiday, I’ll be shown as available.

Is there a way to change the availability for holidays from Free to Busy?

We’ve recently switched to Microsoft Teams and I’d really like to add a “Chat with me in Teams” link to my signature.

Is this possible?

My colleague granted me permission to her mailbox but when I try to add it to Outlook I get the following error;

Cannot display the folder. Microsoft Outlook cannot access the specified folder location. The operation failed. An object cannot be found.

When I try to expand the folder list, I get another error;

Cannot expand the folder.

She double-checked the permissions and even set it to “Owner” level but I still can’t access it from Outlook on my computer.

How can we make this work?

I’ve just updated to the latest Office 365 version and my To, From, Cc and Bcc fields look huge now in comparison to what it was before I updated.

Is there any way to revert them to their normal size again?

I have a very large mailbox and luckily my Exchange Online mailbox has a limit of 100GB so I have more than enough storage left for my mailbox.

However, the Outlook ost-file is apparently a lot more limited as I’m getting synching errors and my ost-file is “only” around 50GB in size.

I find it odd that they support 100GB mailboxes on Exchange while the recommended maximum ost-file size for Outlook is still 50GB.

How can I increase the limit for ost-files and make Outlook support larger mailboxes?

We all have these moments; You need to focus and don’t want to get distracted by anything for a longer period of time.

Alerts for incoming emails can be quite a distraction and those emails you thought only required a quick and short responds ended up becoming an essay or a back-and-forth conversation or just totally got you out of your rhythm.

Of course, you could close Outlook and all other applications that generate pop-up alerts or sounds, but did you know about Focus Assist already?
